Rayhall, you must be alone in your opinion that the DNA-1 is superior to the DNA125. Both reviews in Stereophile by ST & KB of the newer amps agree that they are clearly superior to the older ones. Steve McCormack himself agrees, except for his Rev. A of the older ones, which he says may be just slightly superior to the new ones. All the reviews on Audioreview.com of the newer McCormacks praise them over the old. I own a DNA225 & will vouch that it is a superb amplifier, & I used to be a McCormack skeptic.
