Tubes

[Keiko]

So I'm about to get my feet wet with a tube buffer for my rig. A Yaqin CD2 that should be arriving by the end of the week. Something that Joe (hearingimpared) got me interested in when we were jawin' a few nights ago. Jesse (F1nut) has been helpful with some input also.

Anyway, I've been reading up and researching the past couple days and ran across this. It's a pretty interesting read and rounded out my understanding a little bit on how tubes work.

I'm beginning see a tube amp and a second mortgage in my future. Thanks alot Gus! :p

A little tube love in your system has been a good thing in my experience. Depending on your speakers and what you like as far as sound characteristics, the tube buffer might be all you need or want. I started with the pre-amp, and that was all good. Then went to a tube output CDP, rolled some tubes, and it was more good.

[Keiko]

It was a mere 100.00 investment for the Yaqin, shipped. I've been reading a lot of positive comments on various websites about these tube buffers. I'm still not really sure what to expect and I like the way my rig sounds now. I just want to hear what all the fuss is about though.

Would this work with my Adcom Amp/PreAmp?

[AudioGenics]

This processor can be connected in various configurations. It is to be installed between an audio source and a receiver (or an amplifer). The audio sources can be a solid state CD/DVD player, MP3 player, iPod, electric guitar, or computer audio output.

Would this work with my Adcom Amp/PreAmp?

Absolutely Larry. I'm going to run it between my pre-out/main in on my receiver so it affects all sources. But I'm sure I'll play with it in different configurations. That's just my nature. :o

[Keiko]

Not sure what Japan Victors posting Larry because I got that bozo on ignore.

Here's the link that I ordered mine from. I made a best offer of 100.00 and he gave it to me with the free shipping. Best deal out of all the ebay merchants that I researched in case you decide to try it. This guys seems square. I got a tracking number already and his communication with me has been great. I did pay with a credit card to cover my ass though.

Edit: Plenty of positive info on the Yaqin online. Do a search here on CP also. Here's a few good reviews from epinions.

Interesting, thanks for the links. Bookmarked. :)

[lightman1]

You won't be dissapointed< mike. That little HCT 100 I rewired is doing the trick for me. Brock sold me some RFT ECC85's for it and the sound is smooooooth without losing any punch in the mids.
Dig it?

I'm interested to know what you think of the Yaqin. I see them on E-bay all the time and came very, very close to pulling the trigger on the CD1 at one time. The CD2 uses some weird tube designation, however. Some say the CD1 actually sounds better.

I have been completely enthralled with the little Dared MP5 clone I use in my office rig. It's mind boggling how good 13wpc can sound. It's basically a tube buffered input stage with a single Mosfet chip-amp output stage. It really responds to tube rolling.

The more I listen to it driving my 5B's the more my jaw drops. I just bought a Dared Sl2000A (http://www.stereotimes.com/amp040306.shtml) tubed pre-amp to mess around with. Haven't had much time to listen to it. But the reviews are great.

Keep us posted.

[Keiko]

Yeah, I'm pretty psyched. Aesthetically, I like this one better and would of gotten it over the Yaqin had I known. Oh well...If I like what the Yaqin does I might flip it and get the Little Dot later on down the road. Apparently this can be used inline as well between a pre-out.

That's a nice piece H9. I know squat about tubes. The price of the Yaqin was attractive and I figure this is an inexpensive way to get my feet wet. Initially, I was looking at Grant Fidelity. It's just a re-badged CD2 for 150.00 and this guy operates out of Canada. I would have felt better dealing with someone out of N America, but 75.00 shipping to Hawaii was a deal breaker. It's free shipping CONUS and I wanted to keep this under 2 bills. Here's the link for GF for y'all to check out.

http://grantfidelity.com/site/B-283+Tube+Processor+Buffer

A couple of other inexpensive ones I discovered while researching were these by Indeed. Read some good stuff on em' and I sorta like the one with the acrylic plinth, but the power transformers are just to cheap for my tastes.

You won't be sorry with the tube buffer Gus. Although I think I'm having a little problem with mine. I have to increase the gain.

Joe, from all the reading I've done, it's been said that the Yaqin can compete with the MF and at less than half the price. I hope there's some truth to that. You can roll a few different tubes with it as well, although Jess advised me to hold off on that until I listen to it for awhile. Tubes are cheap enough for this and in abundance so I'm going with Jesse's advice. Another thing this one does that the MF doesn't is that you have visibility of the tubes. I'm really looking forward to seeing this glowing next to my rig and finally hearing a little bit of that tube factor. :cool:

[heiney9]

The tube glow is intoxicating. I would never buy a tube piece that I couldn't roll tubes in. IIRC, the MF doesn't allow user tube rolling.

These Chinese units are a good way to get your feet wet and as I've found out, some of them are junk and some are gems. The Dared is a gem and I hope you find the Yaqin to be a gem as well.

I did some research on these recently before buying the Dared pre-amp and am still a bit perplexed at the tube choice in these units. But, there is nothing like spending some quality time with the actual gear and formulating your own impressions.

Rock on and enjoy

Which units did you find to be junk heiney? Any particular models to avoid?

[heiney9]

Which units did you find to be junk heiney? Any particular models to avoid?

None that I have personal experience with but some of the oddball tubes they use in some of the oddball brands has me very leary of them really sounding that great.

Heard on some boards about poor design decisions on MA (Music Angel) brand. It seems to me based only on what I've read, stick with the traditional tube designations (ie, EL34, KT88, 6DJ8, 12AU7, 12AT7, ECC85, 6N1P, etc, etc).

I saw one MA unit that used a pair of F50 power tubes which looked like a deformed Coke bottle with wires sticking out of the top of the tube. Very Frankenstein looking.

Most of the Chinese gear seems to be well built using very traditional circuits sometimes they cut corners on the caps and resistors they use, etc. However some of the gear is crap......marketed to be flashy, etc.

The secret is the Chinese units are usually copies of well known designs and because they originate in China they cost a fraction to build and they can sell them cheaper.......but sometimes you don;t know what you're getting.

H9

[heiney9]

Dared
Ming Da
Bada
Raysonic and a couple others that escape me right now.....seem to be building pretty high quality gear for a fraction of more traditional American brands.

The Dared pieces have blown me away for their cost to performance ratio.

P.s. I am by no means a tube guru........still just a noob, but I've been reading lots of stuff in the past 6-9 months or so trying to get my learn on.

[concealer404]

The little kid in me is transfixed by the acrylic topped one.... I may have to grab one just to see what all the fuss is about.....

[Keiko]

I've heard of Bada and Raysonic. No experience with either of course. As far as this CD2, I read that the 6J1 tubes it uses aren't well regarded. But this unit was designed around them. I won't know until I get my ears on it and spend time listening. I've been reading on in the meantime though and users are recommending 6ak5w, 5654, ef95, and Mullard m8100 as good choices. The 8100 gets raves, but it's also difficult to find. I agree, it is a bit perplexing because with the above tube #'s certain manufacturers are supposed to be better than others, even though it's the same series of tube. I bookmarked this link to use later on as a reference. It's for the Little Dot, but it uses the same stock 6J1 as the Yaqin.

I agree concealer. It does have a certain cool factor to it. I just couldn't get over that cheapo power supply. It would probably be ideal with a laptop, but I wanted something a little more substantial for my rig. If I hadn't pulled the trigger on the Yaqin already, I would've went with the Little Dot MK II. This looks like a sweet piece of quality gear at a very nice price point.

I've looked into those Little Dot's as well. Stay away from the Little Dot 1 as it had some serious heat issues as in overheating. The LD III is the nicer one to get. The heat issues were addressed in the MKII but the MKIII and IV are really nice the MK V is SS.

[heiney9]

Also talk to NJPolker (I think) as the LD's have some synergy issues with amps when used as a pre-amp.

[TSheaZ28]

I recently bought The Yaqin CD2 for my cd player, and I was impressed. Sounds really good! It opened up the cd's a little more. I bought mine for a guy in Canada. The one issue I have with mine, is that the top metal is a little flimsy and it bows in the center. Other than that, I love the tubes!

Edit: Forgot to mention my CDP is a Harmon/Kardon FL8450. Was given to me by a friend of my fathers. Don't know how good of a CDP is really is.

[Keiko]

That's how I'd like to use it to heiney.

Thanks for the input TShea. Are you using the stock 6J1 tubes with it still? I searched and couldn't find a pic of the Yaqin's internal layout. I'm curious to know what's under the hood.

[187CAM]

Tubes.....YUM!

[TSheaZ28]

I broke in the unit using the stock tubes. I recently purchased a set of Mullard CV4010 that a member of AK suggested. The Mullards are pretty similiar to the stock tubes, maybe a little less bright.

Tubes seem pretty inexpensive for this. I read somewhere that the Mullard m8100 is one of the better tubes for this unit, but they appear to be elusive.

Everything else seems to be readily available and fairly cheap. The 6ak5w's are supposed to work well with it to. Here's some matched Raytheons for 10.00 a pair on ebay ripe for the pickin'.

I picked a pair of them today before they got too ripe! I just got the Grant version of the tube processor and was looking at them on Ebay. He has 8 pair left. The stock tubes are really bright so I am hoping that these will be warmer.

I also ordered 2 pair of Frank's analog 2 cables to put on it. I just hope they get here tomorrow.

[Keiko]

I'm going to let mine burn in before I roll some different tubes. I got a nice pair of MIT's waiting for her. :)

[Dagoods]

I do plan on letting the stock one's stay in for the recommended 100 hours for break in. Just wanted to have an extra set to go to when the time comes to try them. Tubes are so cheap it makes it easy to have extra's around to try.

I have the Project Tube Box SE II and 3 sets of tubes for it that I switch around depending on what music I am listening to. Part of the fun is trying new tubes and seeing how it changes the sound.

have had this for about a month now and getting ready to try some different tubes....have about 100 hours on it,sounded very nice after 50 hours,before that a bit like the "towel over the drivers sound",muffled,at least to me....friend who bought this for was also told it is best to let it burn in with the stock tubes and then try some different ones.............have enjoyed it so far..............nice bang for the buck...enjoy yours..........

I have a question for you if you don't mind. During break in does it require a signal being passed or is just having it powered on enough? I agree with the "towel" comment and can't wait until it as the hours on it.

Not sure what you mean Russ. I'll post the specs below. I'm still waiting for mine to come in from China.

Vacuum tubes: 6J1 x2
Input sensitivity: 0.55V
Frequency response: 5Hz～500KHz(-1dB)
Harmonic distortion: ≤0.15%(1KHz)
S/N: ≤60dB（A）
Weight: 1.9kg
Size: 250 x 185 x 210 mm
Power supply: 110V-120V,220V-240V 60/50Hz

Thanks for the heads-up Notasuv. I really have no idea what to expect at this point. This is a new venture for me.

[heiney9]

Mike, those internals you sent me look scary, but since it is point to point wiring and a small chassis I wouldn;t worry too much. Can't tell the quality of the parts........and that's the key.

Like I said the 6J1 is an oddball tube and I've found any of the stock Chinese tubes SUCK compared to equivalent NOS of other brands. You bought it right, use it, break it in, roll some other tubes in it and see what you think.

[Keiko]

Hopefully it's not as bad as it looks H9. LOL! That did look scary though.

Question for anyone that might know. I've been tracking this thing. Right now it's in Customs USSFOA. I think it's in San Francisco now. I've never ordered anything from China before, so my question is, will there be any additional Duty fees on this? I'm not sure either how long it takes for this kind of stuff to clear Customs. :confused:

Thanks

I just pulled the trigger on the cute acrylic topped one, should be here early this coming week. I'll post up thought when i get it. :)

Should not add more than a day or two and there should be no extra fees...have ordered a few items from
China on the bay before and never a problem, have always used sellers with good ratings and lots of feedback....

[Keiko]

Cool Suv. I didn't think it was an issue...I did exactly what you said. Used a seller with a good rating and lots of feedback. I covered my okole further and put it on my cc.

I would've bought this from Grant Fidelity out of Ontario, but 75.00 shipping for a 5LB amp is just outrages.

[rubin]

I have a tube buffer and a tube pre.When used together (buffer on the cdp outputs) I don't like the sound.It seems they are fighting each other.The buffer used with my ss pre works better.Overall I prefer the tube pre over the ss pre/buffer combination.

[Keiko]

My Yaq arrived about an hour ago and I finished patching it in. I must say, first of all that I'm impressed with the quality of this little unit. It's kind of industrial in it's appearance and has a solid feel to it. Packaging from the factory is equally impressive. When I opened the box I discovered the unit was completely sandwiched or encapsulated in durable foam blocks all around.

Once I patched it inline between the pre/main of my Yammie I plugged it in and let it warm up around 5 minutes before playing a music source. Upon turning it on, the front of it, a plexiglass material, illuminates up with "Yaqin" in a cool blue light and the little tubes began to glow in a warm orange. Pretty neat, I'm thinkin' :D

So, how does it sound? Well, for the past half hour now I've been using my iPod as the source. (It's hotter than the Devil's di*k right now and I'm bein' lazy) It's subtle, but definitely brighter. Drum cymbals and vocals seem a tad more forward. No change as far as I can tell in the mid and low end. If there is, it's too subtle for my hearing.

I know I need to let this burn in for awhile before coming to anything conclusive. It's hardly been half an hour and I need to try it with other sources. These are just my initial impressions that I'm sharing with you guys. Once I get some more burn time on it and do some more listening, I'll report back. I do like it for it's aesthetics right now and those tubes are kinda hypnotic. :cool: Stay tuned, more to follow....

We like tubes around here; you will too.

Mike does it have a power switch or is it meant to be left powered up>?

[Keiko]

It has a power switch Joe. I'm wondering if I just leave it on after I shut down the rest of my gear if that will hasten break in time?

[hearingimpared]

That would be my suggestion as I leave my gear powered up 24 x 7. Although I would leave a source on in loop mode with your preamp on too during the break in period.

[Keiko]

Will do Joe. Too be honest, I'm pretty pleased with this purchase. I'm eager to hear how it sounds in the next week or so. By then I'll be looking to try some different tubes. This little amp does add it's own cool factor to my rig. It was relatively inexpensive and has given me something new to learn. That's what's fun about any hobby.

mrh, those pics are cool. Almost haunting in effect. :cool:

[Keiko]

Perhaps not so subtle as I thought guys. She's starting to open up a little now. The highs, although a bit forward are really sparkling clear now. I always liked the detail of my RTi's, but with this little buffer I believe they're sounding more refined. Mid range I believe is beginning to sound a little smoother too.

On acoustic pieces I'm hearing fingers moving along the frets in more detail. Just too confirm what I'm hearing, I bypassed the Yaqin and listened to the source without it. No doubts, there's an absolute, positive change in sound quality. I think it's safe to assume at this point that it's only going to get better. :D

Jesse, if you're reading this, I went against your advice and ordered 2 Raytheon 6ak5w.
10.00 bucks for a matched pair. That's not enough to break the bank yet. And not out of disrespect bro, but I'm confident now I got a keeper. It's going to be at least a week before they arrive and I'm just eager to try some different tubes. :o

I'm lovin' it!

[TSheaZ28]

You'll really be surprised with some other tubes. I really started loving mine with the Mullards. I recently bi-wired my Monitor 30's, and I think I have the setup that I have been looking for! Now I need to find some nice Cherry Stands!

[lightman1]

Welcome to the dark side, Mike.:D
You got me thinking about looking for another tube pre now. Just to see how it compares to the one I have no, which by the way has settled in nicely. Thanks H9.
I've eyeballed the Yaquins and was a little sketchy about price v. performance. Keep us posted and convince me.

That pre is almost as smokin' hot sexy as you, sugar-bitches.;)

[Keiko]

I have no complaints with the Yaqin so far Russ. If I hadn't bought it first, I probably would have went for one of the Little Dot's though. I didn't discover these until after I pulled the trigger. The MKIII and MKIV are as sexy as any pie I've seen. :)

[lightman1]

Yep. I've seen those. The MKIII looks like my next step. Seems a little more forgiving on the tube rolling.
As soon as someone buys my kidney, I might give that one a spin.
Thanks for refreshing my fading memeory with the links.

[Keiko]

I'm seriously considering getting the MKIII down the road and using the Yaq strictly on my phono stage....Or maybe I should just go all out, steal both your kidneys dude and get a tube amp. :D

I was checking out the Dared's H9 pointed me too. He posted a link somewhere's. Those babies lQQk sweet!

I don't believe the Yaqin is shipped with Russian tubes, I believe they are Chinese variants. Correct me if I'm wrong Mike, but your Yaqin shipped with Chinese issue tubes, correct?

I do know the Shungang 6N1's shipped with the Dared MP5 are pretty crappy as are the Shungang 12AT7's shipped with the Dared Sl2000A I recently bought. I can assume the same for all Chinese based tube equipment. They all ship with stock Chinese derived tubes and pretty much all suck compared to NOS of proper brands, IMHO of course.

Yep. It comes stock with the Chinese 6J1 tubes. Too me they don't sound bad, but I haven't compared them to anything else yet. They seem to put more emphasis on the high freqs.

And yes, it was the Dared pics that gave me a woody. :D
That amp just looks too cool. More like a work of art. I really like the wood accents used in it's construction. Nice touch!

Once you roll some nicer (ie; more balanced tubes) you'll realize how poor the Chinese tubes are. I'm sure the Yaqin sounds nice, but wait until you get a quality NOS tube you like; you'll really light up!

The Dared looks even better in person. Neat little pre-amp, especially for the $$$. I do need to find the correct tube(s) however. It shipped with 60's RCA 6201's and they are really bad, IMO. I am now using some RFT 12AT7's and it's much, much better. Running this with the new gainclone amp I also just bought, in the office rig. Jury's still out as it's all to new to really comment at this point.

Just having fun experimenting and rolling tubes :D

I should have said that they were originally a Russian design/built tube.

That's the philosophy. ;)

Once I spend some more time with this and try some different tubes I'll report back. I just got me new, used Mofi CD of Rush-Moving Pictures delivered and gotta big, sh*t eatin' grin on now. :D

Cue up YYZ and turn it to 11. One of my favorite albums. Neill Peart is a drumming freak on that track.
Wish I was there with you, holding one of those pineapple drinks that have the umbrellas in them...GOOD TIMES would be had.;)

Just bought 2, but I think the shipping calculator upon checkout is fuxored.
It added it as 12.00 for two tubes. According to the description it should only be 6.00 bucks. :confused: I requested a total.

5 left as of right now if anyone else is interested. These are supposed to sound really nice with the Yaqin CD2.

[Dagoods]

Thanks for the link! Now their are 3 left and it told me the same thing. $12 for the shipping.

Click on 're-calculate total' in the payment screen. That should correct it. ebay's been making changes again and this may be a processing glitch.

[heiney9]

A question for the tube guru's.

Every time I power up the Dared the right tube flashes real bright for a second down by one of the pins at the base of the tube. The tube seems to operate fine. Any worries this is possibly a defective tube or it's on its way out? These are NOS RFT's probably from the late 60's early 70's with a bout 6 total hours on them. Anything to worry about?

Thanks

OK, I got the 6AK5W Raytheon's today and rolled em' for the 6J1 stock tubes. At first I thought these sounded really sterile, but not now. :D I would describe these as much more livelier and providing an illusion of a wider sound stage. Highs seem to roll off more accurate and vocals sound more balanced with instruments, not as forward best describes them. A much more refined sound than the 6J1.

It's going to be at least another week or two before the Mullard's get here. Which are supposed to be an even better tube. I'm really looking forward to these and will post more thoughts after I get the M8100's.

This little investment has been paying off so far and I'm having fun with it. If/when I decide to upgrade, (heiney) it's going to be the Dared SL-2000A. The Little Dot is nice, but the Dared is simply elegant. I want it! And I shall have it!!! :o

More later,

Mike, I'm not just saying this because I own it, but the Dared is a special piece among entry level tubed pre's. 2005 and later models had the Auricap coupling caps and this is one sweet sounding pre. Ordered some 6211 as well as well as some 5965 tubes to roll into her. The 60's RCA 6201's sound really sweet so far.

I highly recommend this pre and it really responds to tube rolling!

I saw one on ebay over the weekend for 359.00 brand spankin' new! The seller was also including a USB DAC with it as a package deal. If I had the coin I would've bought it. I'm going to sacrifice on other purchases for next couple 2-3 months and look into snagging one. I might flip the Yaq then, but I think it would work well on my phono stage with the Technics. I got my mind set on the Dared and think it would just look so damn sexy on the shelf above my rack....Heh! I'm having tube fantasies now. :D

[Keiko]

My mistake. 459.00. Still a pretty decent deal and I'd prefer to buy new.

Yeah, I've seen those for awhile. I'm 99% certain the seller is Pacific Valve right here in Illinois.

There are a couple nice units on Audiogon. Always ask which model it is and try to get the unit with the Auricaps. If it has the wooden remote that's the latest model w/all the upgraded parts. There were some units (like mine) that came with the old "keychain" type remote that had Auricaps as well, but not all of them with the "keychain" remote have the upgraded caps and resistors. Still a very nice pre-amp as well, it just needs to be reflected in the selling price.

Good luck

[Keiko]

Thanks for the heads up Brock. Before I pull the trigger on anything I'll spot with you first.

[heiney9]

Also FYI, I'm getting some extra pairs of all the various 12AT7 type tubes that fit in the Dared so if/when you do get one I can give you a good deal on some great tubes for it. So many people are selling 4 and 6 lots of tubes.

Just keep it in mind.

[Keiko]

Will do. I just need a couple months to come up with the funds for this. Thanks Brock!

Shhhhhhhhhhh......don't tell the world! We don't want all the tubes to be bought up! :p

[lightman1]

My neighbor has an old RCA console TV. I'll crack it open and swipe the tubes.
Sounds like Mike has a tube woody.

[Keiko]

Rolled my first tubes today for the Dared. A fatty Sylvania ST 5V4G rectifier and a pair of Mullard NOS CV4024 12AT7's. :D

To say I was immediately floored by the difference between these and the stock Chinese tubes is an understatement. I have some NOS Siemens and Sylvania 5Y3 on their way and can't wait to try them as well. I wish I had gotten into this years ago. Tubes are fargin shweeeet! :)

http://www.freeimagehosting.net/uploads/1f07d040f1.jpg (http://www.freeimagehosting.net/)

Here's a pic of the new 5V4G Sylvania rectifier in the SL-2000A now. I would describe it as "voluptuous." :cool:

[heiney9]

Told YA!!!!!!!

Congrats...............the Dared is certainly a "sleeper". So you did get the 5Y3 to work. I put one in and got an acrid burning smell. I'll try it again, except your's in a bit newer than my Dared...........but that's houldn;t really matter as they are all the same except for some key resistors and caps that are upgraded to better ones.

H9

P.s. The mailman just left me a 5V4GT Coke bottle 1950's RCA rectifier.....Woo Hoo!!!

[Keiko]

Haven't got the new 5Y3 yet heiney. Should be here by tomorrow or Monday. The Siemens will probably be later in the week since they're coming in from Europe. The 5V4G pictured above is what's in it now. Along with a pair of Mullard, CV4024 12AT7 tubes.

It's almost like I have a whole new rig. That's how much of a difference this has made. Looking forward to trying some different flavors in tubes. I'm really pleased with this investment.

The Mullard M8100s I ordered awhile back for the Yaqin came in earlier this week too. Very nice sounding tubes.

[heiney9]

Get yer self a pair of 1950's GE 5 ***** (star) 6201's. You can tell the early ones because they have black plates and a 3 mica spacers, the third is up top for added ruggedness and very low noise.

HOLY CRAP talk about a huge, deep, wide, high sound stage. The biggest I've heard so far. I'm also using my 1954 CBS black plats d-getter 5V4GT (coke bottle) rectifier.

Life is good so far!! :D;)

[heiney9]

Yep, I read that. I'd mostly agree with his assessment. Especially his statement(s) about each instrument having it's own "spotlight". Pretty amazing tube as far a wide open stage, perhaps a bit bass shy in my system. Don't agree it's only good for techno/club music.

[heiney9]

I am having a local get together tomorrow mainly to hear the Emotiva cdp that LessIsNeverMore has in his possession. Doug is bringing his Gary Dodd modified Rogue 66 tube pre. I wanna see how the Dared stacks up against it.

H9

[Keiko]

If I ever start listening to techno, I want you guys to kick the sh*t outa me. :p :D

When I rolled the CV4024s I immediately noticed a wider, deeper sound stage. Also a very nice improvement in mid-bass. Ricardo said when he tried the Mullard's they sounded lifeless in his Dared. Although he pointed out they could have just been bad tubes. I find the ones I have far from lifeless. Can't wait to hear what the Siemens have to offer since he said his Dared sounded best with these. I think having these fine interconnects attribute to the good sound I have also.

Edit: I'm interested in what your impressions are Brock so post your thoughts please.

I will say Luminator is a great reviewer but the GE's aren't anywhere near as mediocre as he makes them out to be. Perhaps against the best of the best 12AT7 or variant they fall short. But I really like them, no tube so far has done everything single thing "right" in my eyes. They all have their strenghts and weakness. If you run across a pair for <$40-45 don;t hesitate.

[heiney9]

I have a single Mullard with the Heath brand stamped on it. It's an older Mullard with the 4 seam top and D-getter. It's NOS probably from the early 60's, used in Marantz and Fisher tuners. A guy on e-bay has an exact match as far as date/plant codes (it's also has the Heath brand stenciled on it). With shipping he wants $45 for a single tube. I'm tempeted but that seems a bit high. I might pull the tigger to try them together. I got my single from a friend of mine who bought a "lot" of tubes and this was in there. He can;t use it.

[Keiko]

I got my pair here Brock. They ship fast and I doubt you'd be disappointed if you decide to try them.

I think this is the single, most important thing I've learned on CP. Every component has it's own flavor and it's all subjective to the listener. If everything sounded the same it would take all the fun, experimenting & enjoyment out of this wonderful hobby. Rock steady bro. :cool:

That would be a real feat mrh considering my gear and speakers being used. For a pair of bookshelf RTi's and NS10 Monitors it ain't half bad though. :o

[royalty]

SO lets say I was thinking about purchasing a yaqin. Would you say that would be a good idea Keiko? Would I actually hear a great deal of difference with it? And does it provide a warmer sounding system?

[Keiko]

Well, I started out with the Yaqin. It impressed me enough that I took it a step further. In just 2 weeks of having it, I pulled the trigger on a Dared SL-2000A.

http://www.dared.us/SL-2000A.htm

As far as hearing a great deal of difference, I think that depends on your ears royalty. What I notice most is better mid-bass in my system and more sparkle on high freqs. Before, I think my rig lacked a bit in the mid range. Of course this is after I rolled the stock tubes for some NOS. I have more coming in, so I'm still learning & experimenting. If you think you'd like to try, here's the link I got my Yaq from. Take a look at the Little Dots too. I've read some good things on them as well. Specifically the MK II (2) and MK IV (4). 145.00 and 299.00 on these pieces. Quality looks outstanding at their price point.

http://shop.ebay.com/davidzhezhe/m.html?_nkw=&_armrs=1&_from=&_ipg=

I made an offer of 100.00 for the Yaqin and he excepted. Honest seller, good communication and I had it in less than a week with free shipping/tracking from Shanghai. I have some Mullard M8100 tubes in it now and it sounds very nice. I rolled some Raytheon 6AK5W tubes with it also and had good results. NOS tubes for the Yaqin and Little Dot are fairly inexpensive and easy to find. If you get one of these and decide it's not for you, I'm sure you could flip them easily.

Cheers,

Mike

[CVSO915]

I have a Yaqin tube buffer hooked up to my totally restored Marantz 2245 reciever and Dynaco A-25's. It wasn't bad and then I rolled tubes to a pair of NOS Siemens and now it is great. I love this thing!
