According to Steve McCormack's website:
Q: What is the actual power rating of the DNA-1 amplifier? I have seen references to
150W per channel, 185W, and even 200W – were there different versions with different
power ratings?
A: All DNA-1 amps have the same power capability. I had originally rated the design at
150 Watts per channel (into 8 Ohms) simply to be conservative. After 2 years or so, the
decision was made to change the rating to 185 Watts to more accurately reflect the real
power at clipping. Given that there are small unit-to-unit variations, some DNA-1s will
deliver 200 Watts per channel.
