bridged pair of mc2250s with c-28 not even touched this dna2

Limitless power, much more musical through the midrange than most SS amplifiers....

No handles...this beast is almost 100 lbs and it's hard to move by yourself.

Let me start by saying that I've owned both the DNA-2 Deluxe and a separate DNA-2 Deluxe with the full blown Rev A offered by Steve McCormack. The differences are pretty significant. But with that said let me start with a review of the stock DNA-2 Deluxe. What a value! This truly a remarkable amplifier sounding much smoother & fuller than the CA-200, CA-201, CA-300 or CA-301, all of which I've personally owned. I also believe that this amp if more musical than either Levinson or Krell....are you beginning to get the impression that I really liked the stock DNA-2 Deluxe? Yup! The Pass X250 & X350 are a 'skosh' smoother in the upper midrange than the stock DNA-2 Deluxe, but when you listen to the DNA-2 Deluxe with the Rev A, then I can easily say that I've NEVER heard another SS amp that is smoother, period. The original msrp on the stock DNA-2 Deluxe was $5000, but can be found for $2,500 or so on the used market (depending on PCs, condition, etc.). The Rev A from Steve McCormack cost $2,500, period, and a used Rev A can be found for around $4,000-$4,500, again depending on condition, PCs, etc.). The bottom line is the Rev A is LIMITLESS in it ability to get the most out of hard to drive speakers. I still find it hard to believe that a SS amp can sound this musical through the midrange. Remember, I'm a tube head and have owned many, many high powered tube amplifiers. I will not say that the DNA-2 Deluxe or the Rev A unit is more musical than a high powered tube amp, it's not. But the draw backs of owning a tube amp (heat, maitenance, distortion & noise) are sometimes intolerable. I live in Texas and my Sonic Frontiers Power 3 monoblocks made me run my A/C continually in the summer. But the bottom line is the McCormack DNA-2 deluxe is an excellent amplifier, and the Rev A is simply the best high powered SS amp I've owned...and I've owned a ton....check my FB on AudiogoN under 'Scubadaddy123'. I'm currently using a BAT VK-5i tube preamp with the Rev A, and I think I've found the best of both tubes & SS. It is a wonderful combination and I highly recommend both pieces. Enjoy the music

I agree with all reviews below. I have owned the DNA2 LAE for 1 year. I upgraded from 2 Golden Tube SE40SEs. This amp has big #$@$%. My input is how to really make this amp sing. I first purchased a Polycrystal UHD amp stand ($325). This was much better than sitting on MDF board. When I replaced the 3 polycrystal cones with 1" diameter ball bearings with undersized silicone tubing placed on to the ball bearing (from Rosinante Dark Matter shelf supplied hardware), the transparancy,speed, and palletability took a major set forward. Use of the ball bearing feet directly couples the amp to the nonresonating Polycrystal UHD stand. All of the attributes listed in the IAR review are further enhanced by this tweak.

Huge soundstage (width & depth), clear imaging, fast, well-
defined dynamics. Tremendous value!

This is an upgrade from the Krell 300i integrated, running a pair of Revel Studios. I had been considering Mark Levinson or Krell power amps for much more money (7-10K for similar sized 2 channel power amps), but when this unit became available as a demo for $3,000 from my local dealer, I couldn't resist a home audition. The improvement from the Krell integrated was NOT subtle! The Studios sounded wonderful on the Krell, but the comparison with a power amp which provided the power they'd been thirsting for was amazing: the most noticeable change was the soundstage, which immediately gained 25-35% in both width and depth. The inner dynamics (as opposed to overall sound level) were improved dramatically, particularly on large symphonic music. With smaller, acoustic jazz recordings (particularly vocals), there is a new-found warmth with the McCormack, and better imaging of the instruments within the soundstage (when that information is available from the recording). On loud, percussive music (e.g. latin big bands, Dave Matthews Band, etc.), the Revels now sound more "relaxed" than they did with the Krell: it's hard to describe, but before you could tell that the 300i was not quite enough amp for the Revels, now they have access to the power (both quantity and quality) which they were missing before. Inner dynamics are more audible, there's more "air" around the individual horns within a big recording. I did extensive comparison of the Krell 300i vs. a Conrad-Johnson PV14 preamp (the Krell can be used as a pre-amp). I ended up choosing the C-J, but the differences here were relatively subtle, much smaller than the improvement of putting the McCormack DNA-2 into the system. I comment on that comparison on the C-J PV14 review, but for here suffice to say that the McCormack sounded great with both the Krell and the C-J, but definitely resolved the differences between them, which were largely what you would expect for an entry level Krell solid state pre-amp vs. a tube pre-amp.

I am a tube fan, I will admit it right away. I owned an ARC VT-100 and currently own Sonic Frontier Power 3 which will put most tube and solid state amps to shame. I recently sold my Sonus Faber Extrema and bought a pair of Dynaudio Confidence 5 with Esotar drivers thru out. Not a good match to my SF Power 3, so I thought I would go solid state shopping for anything less than $5k. Dynaudio Confidence 5 is very revealing on top, more than the Extrema which is one of the king in resolution. I could not stand listening to anything I borrowed from stores until the McCormack DNA-2. Almost anything had that veilness that is so typical of solid state. What happen to technology advancement in the past 10 years? Levinson is a joke, thin and dark sounding. Classe is rough sounding. Krell is "artificial" sounding, but it could fool lots of people to think it's musical. Bryston is good for rocks, but not music. BAT is a mix bag. But McCormack is very pleasant without losing details and low end. It's a standard DNA-2, not even a Deluxe or LE. While I was happy I found a good sounding solid state amp, it blew up on me after owning it for three weeks. Not the fuse, so it had to go back to McCormack for repair which took over 6 weeks total. When I had to send my ARC back for checkup, it was prompt and packed well, not with the McCormack. If they could improve on customer support, they have the best product at a real world price.

Strengths for the LAE include: refined power, fast, intertransient silence, transparency, imaging, soundstaging, focus,... (I could go on) There appear to be no compromises with this amp.

I wish it were the size of a cigar box.

I have the DNA2 Limited Anniversary Edition (LAE). The IAR review found at the bottom of this web page states things quite accurately.

I'm amazed at how many amps actually veil, smooth, eliminate or distort musical information. The SimAudio Moon W-5 sounds very good as well and even adds a touch of sweetness.

The DNA2 LAE simply does everything better as it seems to just about have it all. My Aerial Acoustic 10T's really sing with this amp.

Out of the used box, it sounded very good. However, with some suggestions from my seller, things really opened up when I did the following:

1. Installed a Foundation Research LC2 line conditioner dedicated to the amp.
2. Moved all components off my dedicated 20 amp circuit except for the preamp and amp.
3. Installed PS Aduio's new wall port outlets.
4. Installed the mechanical isolating spike that came with the LAE at the back of the amp as the manual states.
5. Installed the spikes on my Aerial 10T's stands (finally).

My source and preamp are pretty good middle of the road stuff, but the DNA2 LAE is so transparent, I can hear sonic differences with every little tweak I make.

For the fun of it, I just ordered vibrapods for each component and a Foundation Research LC1 line conditioner dedicated to the Sony SACD player.

If you can find a DNA2 LAE, buy it.

Power, detail, lush midrange, dependable, warm

too much bass, upper mids are grainy

For the money, this amplifier is unbeatable. Lots of detail, lots of power and warmth -- a little like tube sound. Highly dependable. I matched it with an Audible Illusions Modulus 3A -- which is a little light in the bass. A very good match -- except that the grain of the 3A, coupled with the grain in the McCormack, made CDs overly brash. On LPs, the McCormack was almost perfect. Powerful enough to always sound relaxed. If source is not up to snuff, the McCormack will reveal the other components limitations.

I have had this wonderful amplifier for almost five years. I have no complaints.

Have never heard a better amp, period.

Please be aware that there are several different versions of this amp floating around, each with its own sonic characteristics. There is the basic DNA-2, the DNA-2 Deluxe and the DNA-2 LAE (Limited Anniversary Edition). The basic DNA-2 is no longer in production.

Each of these amplifiers can be upgraded to an even higher level of performance by Steve McCormack of SMcAudio at http://members.home.net/smcaudio/welcome.htm. Various levels of upgrade are available. The final result is determined by the upgrade chosen (C, B, or A), not the original version of the amp. Thus, the best way to proceed is probably to find one of these amps used and then send it to Steve for an upgrade. *Used* does not matter because key components will be replaced during the upgrade and the amp will be thoroughly tested and evaluated before leaving Steve’s shop.

It has been my privilege to own a McCormack DNA-2 Revision *A* for a year now. I wanted to live with this amp for a long time before writing a review in order to be intimately familiar with its performance and characteristics.

For those who are looking for the ultimate amplifier for your dream system, you can stop reading right here. This is it! But if you are like me, you like reading reviews. This puts me in a difficult spot because all of the accolades for amps were worn out twenty years ago (on amps that did not deserve it!)

I have been very interested in audio for about 35 years now and have worn out the carpeting in many high-end shops. Like many readers, I have always hoped to own that dream system, and like most readers, I can not afford to buy the wrong component. As a result, I have always done a ton of research before buying anything. Then after I buy it, I continue to do research to find out if I have made a mistake.

The bottom line here is that over the years, I have heard most of the high-end amps out there, at least all of those names you are familiar with. And in all of those years, in all of those shops, I have never heard any amp sound as good as this Revision *A*. I am not saying this just because I own one. If the amp had let me down, I would have replaced it and would have explained why. In this case, there is just nothing to replace it with!

This amp has power to spare and is lightning fast. It can blast you with power of the trombone section of a marching band and thud your chest with a bass drum. The details of the piccolo and glockenspiel in the finale of The Stars and Stripes Forever are clearly audible amidst the cacophony. It can ferret out the nuances of Gil Shahams bow dancing to Pagannini creations or the subtlety of Sylvia McNair shaping her mouth to create specific sounds in complex passages of Messiah. Harpsichordists can be heard releasing the keys, a string can be heard breaking in an orchestra, and even the traffic outside the recording studio in an old MHS recording of the Vivaldi mandolin concertos. In the harmonica piece in Lincoln, it is even possible to hear the slide on the chromatic harmonica.

What a beautiful combination of power in reserve in combination with that smooth, sweet quality of the best tube amps. Detail, transparency, speed, depth, delicacy, grace, compatibility, reliability, they are all here.

If I could think of something else to say, I would say it! My congratulations to Steve McCormack and SMcAudio for the creation of this masterpiece.

To RH:

I would love it if you sent me an e-mail of the IAR Review.

Also, does McCormack have a web site? What is the cost of this amplifier.

Please let me know all the details.

I wish Audio Review hadn't changed the format of these reviews. You might want to post your e-mail address somewhere on the review site so that we can have better access to contacting you.

What to Buy…What to Avoid

Solid State Power Amps


Solid state design has matured to the point where you can choose from a wide range of
sonic capabilities and sonic personalities. Some amps are supremely transparent, articulate,
and fast, while others are veiled and defocused.
Some (Odyssey Design, Plinius) are musically natural, with a wonderfully neutral balance between the best of solid state sound and the best of tube sound. One (Audio Refinement) even goes over the fence, and sounds for all the world like a very capable tube amp. Some (Levinson 33H, Krell 300) try valiantly to smooth and soften the hard edge typical of solid state, attempting to sound musical, but instead they succeed only in being veiled and defocused. Others (ARC 100.2) go for maximum clarity, while letting in some solid state artifacts. And then there are those amps (Chord, Copland, Alchemist --- and to some degree Sutherland, Siemel) that have utterly failed to advance beyond the hopeless artifice of early solid state sound, with its obnoxious glare and glaze that covers and blocks so much of the music. On with the parade.

Class 1a
McCormack DNA-2 LAE

This power amp does everything a solid state amp is supposed to do, and does it all better than any other solid state amp. Its sonic performance across the board is a significant step above the class 1b amps below, and in a whole different league than the big name high end amps in class 2.
The DNA-2 LAE (Limited Anniversary Edition) is much more transparent than other solid state amps, effortlessly revealing layers of musical nuance that most solid state amps, effortlessly revealing layers of musical nuance that most other solid state amps don't state amp. Indeed, its rise and fall time is so fast on music's transient treble details that each fast nuance is executed more individually, with better intertransient silence, than other solid state amps---yet at the same time each fast nuance sounds more delicate through the DNA-2 LAE, because it does not sluggishly linger at the peak or get clogged up there, as other solid state amps do to varying degrees.
Some amps try for musicality and delicacy by softening and defocusing the music, smudging and veiling everything (cf. The Levinson 33H and Krell FPB below). The DNA-2 LAE doesn't need any such trickery; it can go for full articulation and sharp focus focus, yet still sound accurately musical and delicate, because it is so capably fast and transparent.
The DNA-2 LAE is so capable that it handles the entire spectrum, and all of music's demanding complexities, with the remarkable sense of relaxed ease that is a hallmark of a truly great audio component, as we discussed above in our Fred Astaire analogy. And this amp's sense of relaxed ease does not diminish when the music gets loud and/or complex. It's 300 watts per channel are accompanied by high current capability, so it plays music's dynamics with seemingly limitless reserves. Most other amps start straining or getting congested at higher volume levels, but this one stays clean, clear, unflustered.
Its sense of relaxed ease, even when playing loud and complex music, give it an aura of dynamic authority that inspires confidence in the listener, and actually makes for more relaxed listening. There are some other macho amp that can play loud , but none also has the articulate transparency, speed, and delicacy that the DNA2 LAE does. It is a rare feat for any power amp combine such powerful authority with such delicacy and nuance at the same time. Among solid state power amps, none accomplishes this feat as masterfully as the DNA-2 LAE. If you want even greater power reserves, each DNA-2 can be bridged to become a monoblock.
The DNA-2 LAE's powerful authority reaches to the other spectral extreme as well, plumbing the lowest depths of bass. Many solid state amps actually sound too constipate in the bass, refusing to let the bass bloom in a naturally rich and relaxed way (for example, they make the strings on a plucked double bass sound too tight); this might be related to these amp's inability to sink return currents from the woofer's reactive nature. Conversely, a few other solid state amps, and many tube amps, are too loose, soggy, and woolly in the bass; they can't put out the large current required to adequately control a woofer, and/or they have internal problems with bass transient response.
The DNA-2 LAE gives you the best of both bass worlds, and provides the best bass we have heard since the Citation 16. Like the big Krell amps, the DNA-2 LAE grabs a woofer and decisively controls it, providing superb bass definition. But, unlike amps with constipated bass, the DNA-2 LAE lets the bass open up in a rich, relaxed way.
You'll hear this amp's superb pass on music, where it counts. But we also put it to an interesting atypical test. On the original Bose CD pressing of Chesky's Women of Song, there's a horrific bass transient in the song Brick House (perhaps someone knocked the mike stand for the right channel). On the scope, this bass transient can be seen to occupy several cycles. The DNA-2 LAE was the only power amp that accurately reproduced these cycles of the huge, very deep bass transient, and actually made the woofer track each of the cycles of this transient. In contrast, other amps just emitted an indefinite burp when this bass transient came along.
Stereo imaging is superb in all aspects, with better width, depth, ambiance, localization, and 3D air around each instrument than we have heard from any other solid state amp. We could go on and on about this amp's stereo imaging, but in truth we expected this superiority. If an amp is truly more transparent and more accurate, it will reproduce subtle imaging cues more transparently and more accurately, so its stereo imaging should be better in all key aspects. Indeed, the DNA-2 LAE's superiority in all these aspects of stereo imaging is further indirect proof that we are correct in judging this amp to be more transparent and more accurate than other solid state amps.
The DNA-2 LAE covers the entire spectrum with seamless integration and excellent neutrality, not favoring any part of the spectrum, nor changing character for some parts of the spectrum. Virtually all other solid state power amps change quality in the upper midrange and lower treble, becoming too hard there, and/or they also change quality in the mid and upper trebles, becoming soft and smeared or dull and rolled off there. The DNA-2 LAE sounds consistent for all the music.
The tonal quality of the DNA-2 LAE does not include liquidity or softness, as do some of the class 1b and class 1c amps below. It is not excessively or artificially hard (as are many solid state amps below), but it is still clearly a solid state amp. It shines a very strong light of revealing accuracy on your recordings, without apologies. It does not need to make apologies, since it is so fast, so delicate, so relaxed. But some listeners might still find its illumination too revealing, too intense. If you find this to be the case for your taste, we might suggest that you try taming the illumination with suitable cables that are not themselves hard or bright, and by taking care that your speakers are likewise sweet rather than hard (for example, try pairing this amp with the Vandersteen Model 5 instead of a Thiel speaker system). Incidentally, when the amp is new, its bright light of illumination also sounds a little electric in quality, getting close to the solid state hardness one hears from most lesser solid state amps; but this electric quality gets tamed as the amp breaks in with use (thus, you should judge this amp, and correct other system links, only after a few weeks of playing music).
The McCormack DNA-2 LAE is priced at $6995. This is comparable to or less than the big name high end competition, which the DNA-2 LAE far outperforms, across the board, in all sonic aspects. With this amp, McCormack has firmly established itself as a true high end company, not just a maker of value oriented upper middle class amplification. This amp is a big and very pleasant surprise from this company, and full credit should go to Dave Reich, the design engineer who created the DNA-2 power amps.
We compared the DNA-2 LAE directly to the McCormack DNA-0.5 Deluxe Edition, an earlier design created by Steve McCormack and Jerry Boncer while working a Mod Squad and McCormack. The DNA-2 LAE stands head and shoulders above the DNA-0.5 Deluxe Edition, by a huge margin, and in every sonic aspect you can think of. It's worth mentioning that Stereophiles's talented staff of 21 reviewers found that the sound of this DNA-0.5 placed a competitive second place to the mighty $35,000 Krell Audio Standard. So it makes logical sense that the far superior DNA-2 LAE could significantly surpass the Krell FPB, as we found.
McCormack also makes two lesser versions of the DNA-2, with the same power rating but with lesser versions of premium parts at critical locations. We directly compared the LAE DNA-2 with the entry level standard DNA-2 (priced at $4395). The standard version is very good, but not in the same league as the LAE. It sounds more closed in, less transparent, fast and extended, and artificially harder with some clogging as is typical of solid state sound. We would rank the standard version in class 2, alongside the ARC 100.2 (which has similar hardness problems). So we strongly recommend the LAE (Limited Anniversary Edition) if you can afford it. The standard DNA-2 would still be a great choice for the bass end of a bi-amped system. We have not had the opportunity to hear the intermediate Deluxe Edition version of the DNA-2 (priced a $5,000).
If you want a solid state power amp, the DNA-2 LAE is simply the best sounding one you can buy, at any price.
