Best high current SS Mono amps


I am searching for the best SS amp for 4 ohm electrostat speakers. I would consider tube monos, but I just can not take any buzzing or humming those tube amps have from time to time. I have a very quiet room and often play at low volumes.

Please help me out with your thoughts. I have spent a lot of time on the archives and I just can't tell what to buy. I would like to spend no more than 11,000 used on some balanced monoblocks with high current.

If there is a dead quiet tube amp that fits the bill, please mention it.

Used Krell FBP350MC's or 450mcx will drive your speakers beautifully with ease. Can be found on audiogon well within your budget.
Would suggest that you audition the Parasound JC-1's. The only downside is that they require a very extended break-in. I have also owned the Wolcotts with all NOS tubes including hand picked Mullard EL34's and can tell you that in comparison to the JC-1's they were soft at the top, not nearly as controlled at the bottom and lacking in slam, slow, not nearly as quiet and lacking in low level detail. Having said that, they were very musical and trouble free and imaged very nicely.
