I hadn't planned on picking up a 2 channel amp until round Christmas. I had my heart set on a Mac MC402 or a MC252. They've always been my dream amp if ever there was one. Any..who I was out today & I just happened to stop in my local B&W/Rotel dealer. I've dealt with them before & they're really nice guys. I walk in the one showroom & spot the Rotel RB1090 (380x2) powering a gorgeous pair of B&W 802D's. They sounded superb!!! Tony even put some vinyl on for me which was wonderful. Anyway, I say Tony Rotel doesn't make the RB1090 anymore. I was correct... they have 5 left in stock & are going for $1600. Now I'm tempted, is it a good deal do you think. I know the RB1090 gets nothing but fabulous reviews. It's a savings of about $4k over my dream MC402 Mac amp. What a pickle I'm in. Suggestions needed!!!

In all honesty, I say start saving for your dream amp. Unless flipping gear and trying new flavors is half the fun of this hobby for you.

I agree with Jason for two reasons:
1.-If you buy it new no matter how good the deal is, if you decide to sell you'll probably not get close to what you paid.
2.-It won't sound as good in your rig, unless you buy a TT ;)

Ok Rotel and Mac are not in the same league except the 1090 can hang in there with the big boys. It's a fantastic amp and has enough power to drive just about anything well. Now depending on the preamp and speakers you own or will own, will decide if gooing with the Rotel is smarter then spending the extra cash on the Mac. I'm also a huge Mac fan and want nothing more then to own a beautiful 2 channel mac system with some Kick ass Dyn's or B&W's. Now on the flip side I have installed and went to listen to the 1090 many many times and left thinking" this is in it's own Rotel class".

As far as a good deal new??? Hell yeah. 1600.00, think about it for a minute. Used your looking close to that or as cheap as 1100.00. So for brand new I'm all about it.

Mac gear is the bomb for 2 channel and theater. Once you own it, there really isn't a reason to buy anything else. They drive everything and lose nothing.

Pear -- WTF???

It really depends on how much you want the Mac gear. Do you want it $4,000 as much as the Rotel? Not having heard either amp, will the Mac sound significantly better than the Rotel? I doubt it.

A bird in the hand, I say. Go for the Rotel and use the other $4k that you would have spent on the Mac on your dream speakers.

Also, I think there are two forms of "dream gear": the kind you can barely afford, and the kind that you would only consider buying them if you made a boatload of cash.

Take time to hear different amps in a room with Mac amps on the same system just different amps, to listen to the difference yourself. Go by what your ears tell you, not what the label says.

Good Luck but buy what you want don't waste money on penny anti upgrading,

There's a 252 on A-gon that you can probably grab for 3k. There's also a 402 for 3800. You could always go vintage and pick up a 7270 for $1200-1800. The only negative to the vintage amps is the lower dampening, which may or may not be a problem depending on the speakers you choose.

I must admit the vinyl sounded very seductive played thru the RB1090 & the B&W 802D's. B&W does make some mighty fine stuff. This "beast" has p;enty of power for anything you can throw at it.

For $1600 new the RB1090 won't lose much value on the used market. They hold their value very well. That's one of the points that just might sway me here. This way if I do decide on the Mac down the road, the sale of the RB1090 will really help me out.

But then again, maybe the RB1090 just might be a keeper for a looooooong time!!

10-13-2007, 07:19 PM
I've read up on this beast and have checked out some specs, damping factor >1000, high current beast. EFF the Mac for now. $1600 new, you bring it home throw it in your rig, if it can clear that James Taylor cut with the tympani shots that bottom out on every other amp you've had in your rig then you have the winner. Besides if the Mac is $4k more are you getting four times better sound or are you getting 4 times better eye candy. I don't know about you Phil but I can't hear through my eyes and I listen to music with my eyes closed . . . if it doesn't work out in your rig, you should be able to get what you paid for a one month old beast that has gotten rave reviews and looks pretty cool too!

Also think about what you can do with the extra $4K!~ If I didn't have in the pipeline what I have, I would be giving this beast a try in my rig hell for $1600 that is worth the cost for a second rig's amp. Don't forget the new price on the beast is $2K so you are already making out.

If you want to sample all kinds of amps, then by all means buy the Rotel. I've sampled many amps, but have always been set on one dream amp. I would already own the dream amp if I hadn't purchased all the other amps in between, but if I hadn't purchased the lesser amps, then I would not know how sweet my dream amp actually is.

How much upgrading do you want to do? You waste less money if you buy your dream amp first. As a warning though, if you are like me, you will get upgraditis and want to test the sound elsewhere.

You have two choices.

Either be an aspiring amp whore like me, or settle down and live the dream.

No, I didn't Early. In fact I called another Rotel dealer out of curiousity to see if they had any RB1090's left. He told me they just sold the last one they had about a week ago.

He offered me a Classe' CA 210 (200x2) for $1900, a customer trade in. He said it would run circles around the Rotel. I don't buy that at all. Sometimes you have to wonder about sales guys. I haven't listened to it yet so I really don't know.

From what I've read & heard as it was driving a gorgeous pair of B&W 802D's, that Rotel is one hell of a "beast" amp. I'm sure the Classe' is one fine amp also but I'm not big on believing what the salesman is trying to tell me. I'm still kicking things around.

While those Mac blue meters are somewhat addictive, I've heard Mac amps I absolutely loved, and I've heard ones that I was not impressed with. The last time I really did a direct comparison was when the Phase Linear 400's came out, and I can't even remember which Mac amp was used for the comparison. I thought the Phase Linear 400 was better, and I took it home.

But again, $4000 extra for an awesome set of blue meters, I won't call you crazy for going for it. Lifes short, enjoy the big blue meters while you can :D

What Rotel amp did you have? The RB1090 is pretty much head & shoulders above the other Rotel amps. It is in a class all of it's own. Having control over the bass is one of it's many strong attributes.

Another fellow on a different forum posted the Classe CA210 specs. If they're correct then the sales man was trying to pull a fast one. Here's his findings: 8ohm/100w - 1%THD@1Khz and 4ohm/200w - 1%THD@1Khz. If they're correct then I don't see how it would run rings around the Rotel.

My concern is that a low powered amp (no matter how good) is not putting out enough juice for my speakers. My last amp (Van Alstine OmegaStar EX 220x2) is very highly rated as being a very good amp. It couldn't handle certain passages at a moderate to hi volumn (not even close to being ear piercing) without severe clipping. In my book I need power & high current to really make the AAD 2001 monitors sing.

Early - I'm going to inquire next week about a home trial, I'll keep you posted.

I found the specs on the Classe CA210 amp & the other fellow was not correct in his findings. Here's the correct specs: 8ohm load/200w - 4ohm load 400w. Now that's a lot better looking amp, I might just have to give a listen to. But I'm still worried about it being able to handle my speakers.

I can only tell you that the Classe amp that I had was the best sounding SS amp I've ever heard.

Zero never sold his H20, at least as of a few weeks ago. He uses it during his reviews that he does for Affordable Audio, the most recent review where it is mentioned is in this month's issue.

Venom

Don't know to much about this amp as it has never interested me much. They use the A modules which don't include the SMPS like the ASP modules do. They seem to go the route of massive overkill in the power supply, which works for some.

I personally wanted amps with the ASP module because I like simpler signal paths. With everything integrated there is a very short signal path and not much in the way of the sound. Not to mention the SMPS is extremely efficient and generates close to no heat, plus is very small so you can have 7lb monoblocks putting out 500wpc+. I do respect Zero's opinion alot though, his opinion led me to purchase my SIA Rothschilde A2s and my Monarchy SM-70.

As for the review, Srajan didn't seem to fall in love with these amps as he did with the Bel Cantos. Last I checked he used the Bel Canto S300 for his Gallos, and fellow Gallo owner John Potis uses the Bel Canto REF1000s.

Phil, it was a Rotel, it's damping factor was rated at < 1000, it wasn't that good. I've heard the RB1090 more than once, it may be the best they make, but I wasn't impressed. Don't get hung up on specs.

I think it would be very interesting to try the Rotel & the Classe side by side in your home. You can probably get a 30 day on both. The Classe amps are in a class of their own and if you find that one to be the better amp, you are really a couple of steps closer to your "dream" amp.

BTW Jesse I didn't know that a high damping factor could cause woofer control problems. I always thought that the higher an amps damping factor the better it could control speakers. I remember a damping factor of over 100 was good but below 20 was very poor. Could I have been high on acid during that class too?

I believe that is correct. However, it seems one can have too high a damping factor and that 200 is more than enough.

I toyed with the idea for a while...until I realized that they sell for $4k used on Agon. Anthony Gallo has pots of money to spend on his Refs but I sure don't, I can't ever see myself spending more then 2k for a amp. What are you doing for a amp now, did I read correctly you purchased a Trio?

I agree, it is nice to have a goal in site but that is too much for my budget as well. I did see one for $2300, but was not ready at the time. I am still using the Krell and the Butler back and forth. I picked up the Trio because I heard great things about it and wanted to see want Ice can do. Especially that it can run all day cold, like my Butler. I may end up using it for my surrounds (Dues) you are familiar with, I am sure it will keep those in line, if not my 3.1's.

The trio is a good little amp, I kinda regret selling mine. It has the Ice "sound" but isn't the best implementation of it, but of course that goes without saying as it is one of the cheaper icepower amps.

Nope the Earthquake has been in my basment for a couple months now, I did a comparison between it and the EVS 500Ms (using the highest powered IcePower module) and I much preferred the EVS. Great little amps, 2x the output of the cinenova yet 1/10 the weight and around 1/5 the size...and they run cold even after hours of heavy use.

Ok - back on track here! From my original post I mentioned my "Dream amp" as a MAC MC402. Well things have changed a bit. I still drool when I think about it but I've also been looking at other quality amps.

Here's my list so far: not in any particular order.

Classe' CA201
Bat VK-500 w/ Batpak
PASS Labs X250
Rotel RB1090
ML #29

I'd like to hear your thoughts on the above mentioned amps, especially if you have 1st hand listening experiences with one. It's just so hard to find them at a dealer to get your ears on.

Thanks to Jesse for steering me in the right direction & to Ted for his feedback on the BAT (sounds like he really likes it).

Add the McIntosh 501 mono's to that list. These may be one of the more versatile amplifiers in McIntosh's line-up when it comes to matching a wide variety of loudspeakers. Pretty good sound to boot.

Just to touch on a few topics mentioned earlier in the thread;

- There is this myth that circulates around audio circles where damping factor is a direct reflection of an amplifiers ability to control a driver. This spec alone does not make for an accurate gauge. I’ve heard 1.5w single ended SET amplifiers control large woofers (within its power limits) better than mighty 300wpc, 1600 damping factor beasts (at the same volume). It all boils down to circuit design and execution.

- The Dynaudio Focus / Nuforce 9.02 is a good one. Separately and on different gear, I’ve heard them both sound like crud. This is nothing unusual. It’s all about finding goods that compliment one another.

- I exchanged a PM with a polkie a few days ago in regards to class D products. I will stick my neck out a bit and add verbatim. The truth is, there is a lot of profit in class D. First, the modules themselves are inexpensive to purchase, especially when bought in bulk. Because class D transistors run so cool – there is no need for the manufacturer to invest in heavy and costly heat-sinks. Since most of these topologies can work on modest switching power supplies, the manufacturer can once again save cash by avoiding large and costly active power supplies. When you factor in the money saved on shipping, and well – you’ve got quite an ideal situation going on. Some are just riding the wave and laughing all the way to the bank.

Of course, sometimes there’s more to a high price than what meets the eye. Jeff Rowland’s costs are much higher. They are a larger company that employee well trained staff, running state of the art labs, using custom chip sets that are housed in a very expensive chassis. Companies like NuForce may not put a great amount of expensive parts into their amps, but they have millions of dollars sunk into developing the technology itself. NuForce is their own topology. They are also one of the few new companies today that offer a high end surround sound processor at 1k. That is a rare accomplishment folks.

I like the H2O Signature 150 for two reasons. A) Its value, and B) It’s one of only two class D amplifiers that I consider ‘musical’ in the more traditional sense that suggests the ability to produce an emotionally engaging sound. Please note that I have not recommended the 250, or any other H2O products. Having heard them, to these ears, the 150 just sounds better. It’s sweeter, warmer, more refined, and is a significantly better value than the other pieces.

Focusing on value a bit; The Signature 150 gives you A LOT of amplifier for the money. For $2000 USD, you get a high current stereo amp that is built right here in the United States, dishes out 100wpc with a whopping 1kw of power on tap (four transformers used), a total of 400,000 microfarads of capacitance (200,000 per channel), weighs in at a solid 55 lbs (solid aluminum chassis), plus you get the normal economic plusses that include cool operation and great efficiency (90%). The bottom line is that there are no other class D amps that give you all of this at such a low price point. In fact, there are very few traditional amps that can boast the same claims.

Of course, all the bulk in the world doesn’t mean a thing of the amp can’t deliver the musical goods. To these ears, and on the right speakers, it can. If you want something that is warm and lush, you might want to look elsewhere. But if you want something that is sweet, yet still very dynamic and transparent – this should make the short list. Those worried about a complex circuit should put their fears to ease – she doesn’t sound like a big brute.

- As a follow up, I love Srajans work. While I do not always agree with his assessments, they are nonetheless informative and enjoyable to read. For the record, I encountered identical results with the 250 signatures as he had in the review.

Well – I think this post was long enough…

Pearsall,

Add the McIntosh 501 mono's to that list. These may be one of the more versatile amplifiers in McIntosh's line-up when it comes to matching a wide variety of loudspeakers. Pretty good sound to boot.

Without a doubt they are superb, well over my budget but droolig doesn't cost you a dime!! :D

The trio is a good little amp, I kinda regret selling mine. It has the Ice "sound" but isn't the best implementation of it, but of course that goes without saying as it is one of the cheaper icepower amps.May I ask how it is implemented differently?Is it using a linear power supply instead of a switching supply?

.....they run cold even after hours of heavy use.It's incredible how cool these things run.I have an ICE ASP250 driving subs and just recently built an amp with a pair of the HYPEX UcD 180 modules.Both just slightly warm even when driven hard.

Phil,
You may want to add the Mccormack DNA-500 amp to your list. I have no experience with this amp but in all my research everywhere, this is called one of the best sub $10K amps around. They are $7K new but show up sometimes for under $4k used, in the same ballpark as your Mac. Just a heads up. There is one on the Gon now:

Just to make things a bit more complicated for you.....he he...add to the list this one:

Belles 350a reference (with the slow start unless you want to blow up something).

Maybe implementation wasn't the best word choice, perhaps example was better.

If you look at the Trio compared to other Icepower amps it is pretty bare bones. It uses the lowest powered icemodule without the SMPS, I believe it is a 200A. Nothing special is done to this module, it seems that it is stock with a power supply added.

Some brands choose to mod the modules, such as EVS and Red Dragon Audio. Others have custom implementations made to their specs like Jeff Rowland. Others still will focus on overbuilt power supplies like the H20 models. Some just focus on good wiring, good chassis, and a good power supply like PS Audio and Bel Canto.

If you compare it to other PS Audio IcePower amps for example it is according to Paul McGowan, lacking "a much nicer chassis, the Gain Cells, better performing ICE modules" that the GCA line has.

Thats why I said it wasn't the best implementation, it is pretty much stock icepower.

Doesn't take long does it Joe. A new thread talking about IcePower might not be a bad idea, huh fellows!!! :D

As for the review, Srajan didn't seem to fall in love with these amps as he did with the Bel Cantos. Last I checked he used the Bel Canto S300 for his Gallos, and fellow Gallo owner John Potis uses the Bel Canto REF1000s.
Do not believe everything you read.
Srjan is not God.
Much going on 'behind the scenes' in reviews you may not be aware of.
Suggestion ?
Cultivate a group of audiophiles who not only can hear, but hear like you ?
I think you may find them a tad more objective.
YMMV

It never ceases to amaze me

that you in your arrogance

and sickening pompousness

think that you are God!

Who let you back

on this forum?

You come off as nothing more

than a child looking for attention.

You and your

alter ego ABX

have now

been banished

to the

ignore list.

I'll second that.Was looking for one a year ago but none popped up.Steve also does some great upgrades to his amps if you feel a need.
