I find it hard to believe that a 2700 retail amp can compete with a hot-rod amp that has had 1500 in upgrade parts alone. I talked to steve's technician, and he said I would have higher performance from a hot-rod dna amp. His argument being that the quality of parts found in the Rev A gold would only be seen in 7-8000 amps. I have to agree with him. I'm sure the markup is 30-40% at the retail level. I have not heard the dna225, but I did own the RevAGold and I think it's one of the best solid state amps I've ever heard. Tremendous bass with excellent soundstaging. Good imaging, very neutral with very little solid state grain. I thought it was very enjoyable to listen to. For a big speaker like the vandersteen 3a's, this is a top wonderful choice.
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.
