A_rt, I too am curious, if you are so wise, informed and scientific, how is it that you have no clue to Proton gear I use? And why haven't I ever heard of the stuff you sell/manufacture?
LOL, HYPE, 90% of audio is hype, and the rest is truth, revealing, horrifying, absolute truth from a source via ones chosen speaker system and source player, amplifiers mean very little by way of "A GIVEN" sound. This is more so in dB output when a designer follows a given standard, more then this becomes over kill most times, and more often then not, outright unecessary.
But then you have never heard a Proton sing- have you?
But then you know more then my ears do dont you?
