McCormack DNA-750

I have noticed that recently some pairs of these mono amps with 650 watts/channel/8 ohms have come up for sale. I had not heard of these before but they seem like a good value product at the prices listed. I also understand that these amps were designed by the Conrad Johnson folks, not Steve McCormack. Has anyone heard these? I have liked the C-J Premier 350 in the past and wonder if the DNAs are similar. Any information or experience you have with these would be appreciated. I am looking for a high power amp with a bit of a warm sound. I am considering a BAT 600se and a Premier 350 as well.

I agree with Mitch. Given there is no marketing, I was very concerned about resale value on these units. BTW, the Marantz Reference monos are great. They have lifted my Thiel 3.7s to a much higher level with better bass , dynamics and transparency. One of my better purchases aon Agon.

Are these fully balanced amps or, like the DNA-500, only a difference circuit on the input?

The DNA-500 and DNA-750 monoblocks are fully balanced, fully differential designs. The inputs are transformer-coupled which allows (among other things) the use of both balanced and unbalanced input drive.

Hi Steve. I understand that you and c-j staff codesigned these; is that correct?

How would you compare the sounds of the '750s v. the DNA-500?
