Best monoblock amps for $2000 used

I have a pair of Quicksilver Mid Monos , paid $1050 used, like new only a year and a half old....   honestly if I paid $1895 new i would still feel like it was a tremendous value......   40 watts with stock EL34 which sound quiet good.   45 with KT88s , ive run them with both and really like the KT66 that are in them now.....   put it this way, if i ever replace them I will never sell them.  They are that good.   And if i do it will be with a pair of 120 monos

I concur with Dweller.  In that price range Klaus Bunge of Odyssey can likely build you Khartago amps. I would recommend an upgrade to extremes.  These amps for the money rival anything under $5k and I will tell you I have seen his bigger amps give $10k amps a run for their money.  There are certainly better amps but these solid state units are pretty darn good.  They are built in Indianapolis and based on a German design.  

A pair of wired M-125 monoblocks new would run you $800 above your budget but you'd be happy:

Is Rowland model 1 bridgeable, I don't remember? You can probably find two of them for about $2500 or so.
