I tried recently, to get at the difference between these amps. According to the Stereophile review, a Rev B amp is on par with the new design. According to Steve McCormack, who admittedly "danced" around my question, it might take a Rev A upgrade to get at the new design. It might be that Mr McCormack's interest (financially) in McCormack Audio, and in SMc Audio may cause problems with his recommendations of either one over the other. This is only speculation on my part. Mr McCormack was very, very helpful with my questions. He wrote two emails to me in extreme detail. However, I am no more sure of the differences now than I was before. Perhaps it really is not "better" but different.
McCormack amp upgrade / midbass warmth?
Hi I'm seeking some experiential advice from McCormack amp owners who have had their amps upgraded by SMC Audio. I was seriously considering upgrading my stock DNA-1, until I read the recent McCormack DNA-225 review in Stereophile. He mentions that the DNA Rev. A upgrade, although being a significant overall improvement, resulted in smoothing out the midbass warmth of the stock design. I suspect the "midbass smoothing" may result from revision of the DC servo circuit? This concerns me, because I prefer that midbass-warmth sound in my system (that's why I bought this amp). Of course I am going to consult with Steve McCormack in that regard. Would just the Rev. C, or maybe even the Rev. B upgrade also affect the midbass? I don't want to lose this warm sonic signature, it works nicely in my rig. I hope to hear from others who have done upgrades please? Thank you for sharing any opinions.
