Best tube mono blocks under $15,000?


Currently running McIntosh C2300 preamp and am leaning towards running Mc275s in Mono configuration but I'm new to tubes is there anything sweeter or better out there for the money? Thanks for any input.

Sure,

Right now I have Magico V2's . My current amps are McIntosh Mc501 500 watt SS mono blocks. Cables are Cardas GR thru out. sources are VPI HR-X and Mac MCD500 cd/dac
As we speak ther are a pair of Mc 2301's just under your budget (14995). I would check em out, just popped up in the classifieds.
