Interesting, i would like to have that opportunity , i often wonder if i can truly hear the difference between 2 amps. I am getting a new amp with a SPS vs the one i have with Torroidial so i will see if i can tell any differnce though i highly doubt it. I can see 2 recievers sounding different but amps i am not sure . It stands to reason that they possibly could given different circuit designs and part quality. I mean a capacitor or inductor changes the sound of a speaker when configured in a crossover only stands to reason those same components play a role in a amplifier? Keep us posted as it breaks in ? not sure how that works either. I am a mechanic and breaking in an engine with mechanical parts make sense but electronics idk . If electronics break in then the computer in a car would change how it controls an engine as the computer ages which it most certainly does not. Ah technology so many questions so few answers.
