hi guys my friend decide to buy a secondhand krell kav250p/250a (pre/power) with 2500$. I recommended him McIntosh MA6500 (2500$) and NAD S300 (1600$) for their performance/value. His speaker will be B&W 803 and he will decide later for chosing cdplayer and cables. I want to know your idea about his choice (krell)? Do you recommend a better way for spending his money on amplifier?
