    Default Tube Buffers; Yaqin CD-1 & Musical Fidelity X-10v3

    ## The Setup ##################################################

    There has recently been a great deal of interest in tube gear here in Club Polk, and I'm experimenting with tube buffers placed between my Solid State NAD 1700 Preamp and Solid State NAD 2600A Power Amplifer.

    Both NAD components were professionally rebuilt (power/caps/etc.) by NAD specialists "In House Stereo Repair" in Setauket, NY in March of 2009. I know I could have gone another direction, but I bought them brand new in 1987, they have sentimental value. These components have served me well.

    First, my system is in my home office and I listen constantly (sometimes 60 and never fewer than 40 hours per week).

    My desk is dead center in the SDA sweetspot between pairs of sonicap/mortite/dynamat extreme/RDO-198 modded SDA-2B's and SDA SRS 2's with custom made 12 Gauge 9-Strand Silver Coated Copper Wire SDA Interconnect Cables. Room dimensions and acoustics are absolutely ideal and speakers are optimally placed.

    All Speaker Cables are 10' MIT Shotgun 2 and all Interconnects are 2 Meter MIT Shotgun 2 (with adjustable impedance matching boxes on input side). I also have 2 pairs of 1 Meter and 1 pair of 2 Meter BW Audio Silver Interconnects that I will experiment with if I feel the need to open up the highs, but don't anticipate using them.

    All components above have a minimum of 500 hours of break-in


    ## The Buffers ##################################################

    BUFFER A:
    I purchased a very well cared for Musical Fidelity X-10v3 Tube Buffer from Club member that I have been auditioning for about a week now. The improvement provided is simply wonderful. It is in completely stock condition and came with a decent quality wall wort power brick, but not the list price $400 MF X-PSU-V3. I've researched and ordered a "Little Pinkie v3i Power Supply" from its maker in Scotland that is acclaimed to be better than the MF PSU. I will use a 6' Signal Cable MagicPower Cable to power the Little Pinkie.

    Total Musical Fidelity system delivered price (Buffer/Upgraded Power Supply/Upgraded Power Cable) = $475USD

    BUFFER B:
    I received my brand new Yaqin CD-1 Tube Buffer in the mail today. I did not even take the stock 6N1 Chinese tube out of the box and instead inserted a recently acquired NOS JAN Phillips 6922 Green Label that is said to be an excellent match. I also did not take the 110V stock power cord out of the box and used a recently acquired Signal Cable MagicPower 6' Cable.

    After break in, and when I'm confident I know its sonic signature, I will solder in a couple of high quality capacitors said to improve its power supply a cost of no more than $50 USD.

    Total Yaqin system delivered price (Buffer/Phillips Tube/Upgraded Power Cable) = $200 USD (future caps will make it $250 and I also have plans to introduce a Telefunken 6922 Smooth Plate Diamond that will increase tube budget by $55 USD adder making the comparison grand total $305 USD)

    ## Initial Comments ##################################################

    I've been listening to the Yaqin for about 2 hours now. If I didn't know any better, I could review it with high marks before breaking it in!

    This thread will eventually become even more deeply evolved, but with the arrival of the Yaq, I wanted to get a start today. Analog and Digital source components will be described soon.

    Default Musical Fidelity X-10v3 Tube Buffer & Power

    ###############################################

    Musical Fidelity X-10v3:

    Simple, elegant, attractive.

    * Weight: Unit, net 2.5kg (5 lbs 8oz) un-boxed, Adapter, net 0.45kg (1 lb)
    Total packed 3.1kg (6lbs 13oz)

    ###############################################

    I purchased the "Little Pinkie v3i Power Supply Unit" ($218 USD delivered) instead of the Musical Fidelity X-PSU-V3 Upgraded Power Supply ($250+ USD if you can find one and is said to need a better ($125 USD used) DIN cable.

    (http://www.rock-grotto.co.uk/pinkiepsu.htm)
    Little Pinkie v3i PSU
    -- with Top quality DELTRON Pro 3 pin chassis mount DIN socket
    -- with BLACK Evolution Pro OFC cable terminated at either end with 3 Pin Neutrik metal bodied DIN plugs
    110 for the Little Pinkie + 20 Shipping to USA Shipping Address: = 130 (exchanged to $218.71 USD on 09/06/09)

    Producer Mike Grierson shared, "Unlike the MF X-PSU V3 the Little Pinkie has internal fusing, Class X2 EVOX across the line filtering and an MOV anti surge device which ensures the voltage to the transformer remains constant.... it's not just a "transformer in a box" like the X-PSU V3..... so cryogenic cables are really not required "

    This will save me the purchase price ($179 USD new, approx $125 USD used) of the Revelation Audio Labs Cryo-Silver Reference Power Cable said to be a "Must Have" to make the Musical Fidelity X-PSU-V3 sing.

    Musical Fidelity PSU specifications
    * Large toroidal transformer.
    * Excellent stable source of electrons for all X-Series.
    * 4 separate secondary windings. A completely separate power supply for each of up to 4 X-Series.
    * Excellent regulation. Better sound quality.
    * Power outputs Four, each 12 - 0 - 12Volts AC 20VA
    * Power requirement 100 / 115 / 230 Volts AC 50 / 60Hz (Factory pre-set)
    * Power consumption 100 Watts
    * Dimensions 180mm (7.1") wide
    * 88.2mm (3.5") high including feet
    * 208mm (8.2") deep
    * Weights Unit, net : 3.1 kg (6 lbs 13 oz)
    * Total packed : 3.65 kg (8 lbs 8 oz)
    * Accessories IEC mains lead (10 Amp type),
    * Four DIN - to - DIN type low-voltage leads

    Default Setting some ground rules

    First, let me start by writing that I've seen remarks posted here and there that assert placing a tub buffer in your signal path is "just adding another TONE CONTROL". The same comment has been posted about cables and interconnects. I strenuously object and am learning to depend upon my Tube Buffers, MIT Shotgun 2 Speaker Interface Cables and Interconnects and BW Audio Silver IC's for so much more.

    I've never found a tone control that can deepen and widen the soundstage, increase stereo separation, expose the focal pinpoint of voices and instruments, and just simply "immerse you in the music". There's more at work here than simple frequency attenuation.

    I'm more convinced that it's a "timing" issue, but I don't have the technical and mathematical background to prove the point that way, so all I can to is offer a subjective approach based upon a few decades of listening and experimenting.

    If you read on, you must understand that you are trusting MY ears to be your guide, and it is my sincere hope that this thread does not turn a pi**ing match.

    I hope this will help those who are seeking to improve their listening experience and aren't afraid to try something new.

    I am very interested in your review as well. I ordered a Grant Fidelity B283 tube bufer this past Friday. I think I 've heard or read before that Grant Fidelity products are actually made by Yaqin? Anyways, I'm really looking forward to trying this in my system as well. I've been wanting to introduce tubes into the system for a long time.

    I believe this is true based upon what I've read online. "slbenz" is found in several forums when searching google.com for any of the 3 brands of tube buffer (MF, Yaqin,GF) and seems to write intelligently about them.

    http://www.sound-thinking.org/index.php?showtopic=4002

    The forum above is also contributed to by "Grant Fidelity" who is Ian Grant, the owner of GF.

    I'm just 18 hours into the Yaqin's burn in right now and it's settling in nicely as I sit here listening to the RUSH; Chronicles 2 CD set.

    Dawg...Just a heads-up. The GF B283 is a Yaqin, it's just been re-badged. I'm sure your's will be shipped with the crappy Chinese 6J1 tubes. I've only rolled a couple with mine. Some Raytheon 6AK5W's and some Mullard M8100's. I had read the M8100 is one of the best sounding tubes for this buffer. I can highly recommend them, but they are a little difficult to find. The 6AK5, 5654 and CV4010 (NOS Sylvania Gold Brand, Raytheon, Mullard and Amperex) are good variants for this from what I've researched. Here's a link to an ebay seller where I got my Raytheons from. Not as good as the Mullard's, but a nice sounding tube nonetheless.

    Have fun! :)

    I just did a quick search on ebay. Here's some Mullard CV4010's that are available. About 43.00 total for two with shipping included.

    Keiko,

    Thanks for the great info and links. I'm definitely going to be doing some tube rolling and hopefully with those M8100s! Thanks again.

    Update-Actually I just did pull the trigger on those! According to the link, the price was for a matched pair! With shipping it came out to $44 USD for two sets of matched pairs. It looks like I'll have an extra set for later. Thanks again Keiko!

    Forget those in post #12. These are what you want and at a better price.

    http://cgi.ebay.com/CV4010-EF95-6AK5...3286.m63.l1177

    And for 53.00 & change you can get 8 of these.

    Default Vacuum Tube Burn In Time

    I'm running the Yaq 24/7 to get to the 100hr supposed "total unit" burn in threshold before commenting on sound quality, but that leaves me with several days of research time on my hands.

    Being absolutely new to tubes I realized I know nothing about tube burn in times and thought the next few days

    and found an article at . . . http://www.kk5dr.com/Tubes.html . . .

    where the author answers, " . ."how long should I allow the tube to burn-in, prior to operation?" On a tube that has an unknown amount of shelf time, 10-12 hrs would do well. For a tube that has been in your closest for known amount of time, I have developed a rule; 2 hrs per year of shelf-time. When you "rotate" your tubes, allow them 2 hrs of burn-in time prior to applying RF drive. With a new tube fresh from the factory, 6-8 hrs for large glass envelope tubes, 2-6 hrs for metal/ceramic tubes, burn-in time. A little patience, and conservative use, your tubes should see full life."

    I am most curious about "allow X HOURS of burn-in time prior to applying RF drive." and I would like to get some input from the group.

    I'm new and learning to Greg. I can tell you (IMO) that after at least one full day my tubes started to settle down a bit and sound better. After about 4-5 days the Siemens in my Dared really started to sparkle. When I rolled the CV4024's it was pretty much instantaneous, but over the course of a few days they sounded better also. I got in the habit of letting my preamps warm up at least half and hour before putting any signal through them.

    I hear what you are saying and agree bro, but the guy above says DO NOT APPLY SOURCE for X HOURS, meaning when you get a new tube, turn on the buffer, pre, amp, etc., but DO NOT TURN ON turntable, CD, FM/AM, etc. for many hours.

    He's basically say to "cook" the tube at "idle" with ZERO dynamic signal passing through it for best results.

    Ooops! I already pulled the trigger on the first link you posted. It's all good. I appreciate all of the good info and links! I probably never would have found these without your help. Is there anything special I need to know about swapping out the stock tubes for the Mullard M8100s besides proper burn in?

    Default Tube Damper on Yaqin

    It just arrived in the mail and I realize I forgot to add the $20 Herbie's Ultrasonic 9 in the budget in Post #1 for the Yaqin CD-1, so the delivered price as I am using it now with upgraded JAN Phillips 6922 Tube, Herbie's Tube Damper and Signal MagicPower Cable for comparison purposes is $220.

    I'm at 26 hours now and the sound has settled out very nicely. The highs that seemed a bit "raspy" and as if something was missing or "hollow"when I first powered it up yesterday now sound properly balanced.

    The Yaqins break-in is only half complete so I should refrain from commenting, but I have been smiling from ear to ear all day.

    Also, during the break-in period, I've been toying with the the Musical Fidelity also in the circuit (MF between CD player and preamp, Yaqin between preamp and amp)

    Oh Shinny! Here's the rub, my intent was to determine which buffer best fit my needs over the course of the next 4 to 6 weeks and sell off the other.

    The problem? The sound is BETTER with BOTH buffers in the circuit I can not detect a loss of signal, clarity, soundstage, decay, placement, etc. It just plain sounds better. (looks like I'm in the market for another 4 to 6' Signal Cable MagicPower cable)

    I will pull the MF out to remove dual the variable and then listen to my system with and without the Yaqin Sunday evening when the 100 hour break-in is complete to begin the Yaqin review period.

    I've been meaning to ask, what is a tube damper and what does it do? I know the obvious answer is it damps tubes, but I'm new to the tube world, so please explain what that means and what does it do for the sound. What is your personal experience with what the tube damper can add? Thanks in advance.

    Tube dampers are used to remove microphonic vibrations. These vibrations can be caused by components inside the gear like a transformer, or external to the gear like bass. Either way the vibrations can alter the sound and you use tube dampers to eliminate the problem.

    Personally I have found some gear to be more susceptible then others, for example my Modwright preamp was much more susceptible to micropohonics then other tubed gear I have tried. You could hear a light tap on the top of the unit being played back by the speakers. Tube dampers and dynamating the unit fixed the problem.

    While placement in the room is a huge contributor in most cases, some tubes are just physically more "microphonic" than others. Their specific construction, for whatever reason, simply allows sound waves striking the tube and/or tube device to resonate and affect the output signal.

    Thanks for the replies! I decided to google the Herbies Tube Dampers and found the site. After reading the reviews and looking at some of the other products, I ordered 2 tube dampers and a turntable mat from them. If I like what I hear, I may order one of their cd mats next. Thanks again for the good info. When I first started in the audio world, I had no idea that there were so many "tweeks" out there. It's definitely been a learning experience and I'm enjoying the journey!

    I too want to thank Gaara and Inspiredsports for answering that question. I remember my speakers reproducing some kind of weird sound, even after turning down the volume (with the subwoofer still on). I tapped on the amp and it produced some feedback, then after a friend of mine brought back my amp with a different pair of tubes the feedback was gone. However there were red rings around the tubes and I never knew what they were, I assume those are dampers as well?

    Can't wait for the review, since $ will go to a pre my logical choice would be a DAC as opposed to a new source. Keep it coming!

    It ends up being a very steep and slippery slope. Once you start there is no way back, but if you enjoy audio, it's not really a bad thing at all :)

    Which Herbie's mat did you choose?

    Probably what you see in this thread in post # 13: https://www.polkaudio.com/forums/sho...d.php?p=933206

    Not sure about this type, but the Herbie's like to be dead center with the same amount of showing on top as on the bottom.

    My Yaqin CD-1 is at now just at 100 hours of use so the fun will begin soon.

    Hmm, kind of like that but they're thinner. Although if they [I]are[/] the same tubes even though I recall he switched some out, then they really worked. There's 2 rings each on the outside pair and one ring each on the smaller ones in the middle.
