McCormack DNA 500

Is the McCormack DNA 500 really as great as reported?
Anyone with enough experience to comment?
There would be a big difference between the DNA 225 and the DNA 500.
You shouldn't use the former to compare to another as a basis to conclude on the 500.

And Steve McCormack has mods he is now just doing on the DNA 500 that he did on my 300 watt DNA-2 Rev. A.

Try that on for size and then let's hear some comparisons.
The 500 is excellent as many have pointed out. I do think there is some good advice above to listen to several and buy what is best for your system and ears. I auditioned many, including the DNA500, but ended up with the Cary CAD500MB0 , their new SS 500W Mono's. The McCormack was a very very close second, and in fact the main reason I went Cary was they were so close and my pre and cdp are both Cary. I always laugh when someone says anything is the "best" and leave off "to me" because it's not really possible for it to be universal....FWIW

The new DNA 500 mods you spoke about:

Soft Recovery Diode Bridge
Cabron-Siltech Wire Matrix
Black Gate Bypass Caps

Is that correct?

From my experience, it is EVERY BIT as good as reported. I have owned Hafler DH-500, Hafler 9500 and 9505 (run stereo and bridged), Nakamichi PA 7, and Sunfire 300. Long story short, I currently have Legacy Focus SE speakers, a Pass Labs XP-30 preamp, and 3 years ago purchased 2 McIntosh MC 601 mono block amplifiers new. Since the purchase of the MC 601’s I have been quite disappointed in their bass response. The bridged Hafler 9500/9505 had more weight in the bass region. The Sunfire, Nakamichi, and McIntosh all fall short of the Haflers in the bass department. The McIntosh MC601’s are great in the mids and highs, much better and clearer than all of the previously mentioned amplifiers. I recently purchased a used Mccormack DNA 500 based on the reviews and the fact that all of the reviews mentioned the weighty bass. I purchased it to use only as a bass amplifier for the woofers. I have had it hooked up for about 4 months now running it full range to the Legacy Focus SE’s just to see what it is capable of. So far, I have not even put the McIntosh MC 601’s back in the system on the mids and highs as planned. The DNA 500 is superb. It seems to do everything right from the bass, the mids all the way up to the highs. It is every bit the equal of the MC 601s in the mids and highs – even a small notch less bright (advantage for the Legacy Focus SE’s). IT STOMPS the MC 601s in the bass department. It tops any amplifier I have ever had in my system in the bass department. The term “Velvet hammer” fits perfectly. It is not too much bass, just bass you never realized you were missing with other amplifiers. This helps acoustical music tremendously. An acoustic guitar sounds so much better and real when an amp has the reserves to produce proper bass. I will soon put the MC 601’s back in just on the mids and highs just for comparison. But, so far I have been so happy with the DNA 500 running full range, I haven’t messed with putting them back into the system yet.

I’ve tried many amps with my Maggie’s. Dna 2 made the difference. No need for trying anything else.
