I still remember how difficult it was for me to transition from mass-market to high-end audio. The former, for all its flaws, gave me things to do: switches to flip, buttons to push, knobs to turn, meters to watch. I was in controland if my attention happened to stray from the music or the liner notes, I still had something to keep me busy. By contrast, the first perfectionist-quality amplifier I boughtan Amber Series 70was an oblong box with an on/off switch. Where's the fun in that?
