Newbie Can't Decide Which Tube Amp


Just had a Bottlehead tech build me a BeePre preamp and an MM phono. My speakers are Sonus Faber Concertos Homage (rated at 87dB sensitivity) and my budget is $4K- give or take. I am not much of a bass person. Mostly classical, appreciate the Blues, Latin, and occasional classic rock. The tech is adamant that I look for a used EAR 534.

I appreciate your feedback in advance.

I've been enjoying a Bob Carver Crimson 275 for a couple of months now and I highly recommend it. American made with a 5 year warranty that includes the tubes and it sounds great. You can stick with the stock KT120's, vary the tube bias between 60 and 120 ma and roll the smaller tubes to get the sound signature you want. 
Those speakers need some oomph!

   Consider a minimum of 300 W rms.

 Carver 350 crimson tube monos.

 Those speakers are power hungry, and need some good power. 
@ckenr, with your noted "cramped quarters" and space constraints limited to depth vs. width, you might want to reply with your LxWxH limits.

This might help folks to help you to narrow down a list of possible tube amps(s) you can do given your circumstances. Remember, tube amps need a little space round them for ventilation too.
