Ian,

I am no electronics expert, but I dont think that will be the case at all and I think you may be over simplifying things. I think there is a lot more to sound quality than frequency analysis plots. There are probably a whole host of other measurements such as harmonic distortion, IMD, etc.  that should be measured too.

For example, remember the 1970s japanese mosfet amps that measured perfectly with no distortion, yet sounded awful? What about valve amps that measure terribly, yet sound wonderful? ISTM that we may well be measuring things that are not that significant when it comes to sound quality.

 

Graham,

sorry I dont measure up to your high standards. (There seems to be quite a few of us you have lumped into this category recently)
