I am really curious how the great amps of my time test out, like Krell, Mark Levinson etc. Were they really that great or were the magazine testers hearing the price tag? Or encouraging their ad revenue? I have owned very expensive AVP's in my time, I am disheartened to see a Denon receiver surpass some of the more exotic separate processors. How much of this hobby is based on label worship? Certainly speakers speak for themselves, we can directly hear the differences, but electronics?
