McCormack DNA-750 good?

My understanding is that the DNA-750 is not a Steve McCormack design, but was designed by folks at C-J after Steve was no longer affiliated.
Google Jeffrey Behr over on AAsylum and you can see some great pictures showing how he upgraded his amps. He seemed to really like the results.
I know Steve has upgraded at least one pair and I see he has them listed on his SMc website as amps that he will upgrade.
As far as the sonic level that can be achieved, I have no idea.
However, his upgrades of vintage McCormack gear, DNA-0.5,1,2,125,225 and 500 are outstanding.
Maybe others can weigh in on how the 750s sound in their stock form.
Regarding reviews, just an observation that may have no bearing but, I believe reviewers often hear stuff before they decide to review it. It seems really good sounding products often receive a proportionally larger number of reviews.

Since you asked, I suggest you not rely on "everyone's eyes" when making your amplifier choice but rather rely on your ears. I suggest you listen closely to the 750s before you purchase a pair. I have no doubt they are powerful but they also do not have the universal reputation for musicality of the older McCormack amplifiers (e.g., DNA-0.5, 1, 2, 125 and 225 and 500). I would listen to any of those you can in order to gain perspective and to form an opinion.
