Mark Levinson 331 or McCormack .5 Rev. A

They will not work with the zplugs. You can send your nordost cables back to the factory for re-terminating.

Hey John: To answer your questions about the 3" clearance for ventilation, no problem. I have my 331 on the bottom shelf of a Salamander cabinet. I have the sides on the cabinet. I have about 3" and have not had any problems. The amp runs cool. As for the 331, it is a great amp. However, I have to agree with Charlie. What is up front makes a great difference. But, just as important is the fact that I don't anybody that hears the same. What may sound good to me may not sound good to you. Therefore, you need to make the judgement yourself, with your equipment and cables. By the way, just to let you know my 331 is listed for sale, however, it appears that I have been under priced by other 331's lately....that is what makes this a great site, power of competition. Good luck on your decision. PJ

Paj and Charlie, Wanted to let you both know that I am running my Wadia 850 directly to my McCormack .5 via Nordost SPM (single-ended). Thanks agian for your input...John

I just bought the DNA-1 Delux w/rev A and switchable balanced inputs. It is great sounding. Good soundstage, clean with detail, and excellent bass. It's not quit the match of a tube amp on soundstage, but close. I'm using it with my Vandersteen 3aSigs and Audio Physic Virgo's. It sounds GREAT with both of them. The vandersteens were especially improved. I have liked the sound of every DNA amp I have heard. I have not heard the 331. There was a discussion of its sound in stereophile a few months back. It was the issue where they reviewed the 334. They compared it and did an update to a 331.5 revision. Stereophile currently has a DNA1/A that they in the process of reviewing. They mention it every once in a while.
