Pat Why Do You Do This?

Pat,

I recently read a very informative post from you and thought perhaps you'd changed somewhat. But now I read this post where you appear to be deliberately acting stupidly by asking "So, where is the "measure completely differently in every parameter"? Allow me to explain this for you.

mkuller's quoted Peter Aczel's statement of: "high input mpedance, low output impedance, flat frequency response, low distortion, low noise floor, and is not clipped." as being Peter Aczel's professed requirements of when it will be impossible for two amplifiers to sound different!

Then mkuller wanted to know how Peter's statement could possibly be true when it quite possible that "..the amplifiers use completely different circuits, different parts, at very different costs and measure compeltely differently in every parameter." Yet both still have Peter Aczel's requirements of "high input impedance, low output impedance, flat frequency response, low distortion, low noise floor, and are not clipped!

I agree with mkuller. It's a very fair question. It's quite possible for 2 completely different amps that measure differently to still both have "high input impedance, low output impedance, flat frequency response, low distortion, low noise floor, and not clipped! Or don't you agree with that either?

I also believe that an amp that has a different circuit's design, different types of parts used(electrolytic cap vs polypropylene cap) different quality of parts which would equal different costs and measures completely differently in every parameter is going to sound different than another amp even if both have "high input impedance, low output impedance, flat frequency response, low distortion, low noise floor, and not clipped!

You don't have to agree, but please don't act stupid and ask "So, where is the "measure completely differently in every parameter"? As if Peter's statement didn't allow for that possibility! Peter specifically said: It is impossible for two amplifiers to sound different at matched levels if each has high input impedance, low output impedance, flat frequency response, low distortion, low noise floor, and is not clipped he never said the amplifiers couldn't use completely different circuits, different parts, at very different costs and measure completely differently in every parameter!
