there are any number of accuphase and jeff rowland design group amps (new or used) at the $10k pricepoint that will better any of your current selection of alternatives. they may not mate well with you krell pre, but then what does? well worth hearing, nonetheless.
Best Solid State Amp For 10k Or Less
I'm auctioning off my Aragons to put towards the purchase of 'my last amp'. Wondering what people think. I have a Krell HTS as a preamp and Dynaudio 3.3's as mains. All I'm concerned with at this time is two channel sound...home theater can take a back seat for a while. My 'short' list is made up of Mark Levinson 335 or 336,Krell FPB300C or perhaps the FPB600c if I can find a deal,Classe 401, Plinius SA250. My musical tastes lean towards classic rock and jazz.What do you think?
