Best monoblock amps for $2000 used


Thinking about going the monoblock amp way. I would like to purchase a used pair
with a budget of $2000. Any suggestions. My preamp will be a Jolida fusion.

The SST Ampzilla 2000 mono blocks as well as the Son of Ampzilla 2000 are a different animal from the Ampzilla and Son of Ampzilla from the 70's.  
There is a new Son of Ampzilla II out now also and it is yet a different amplifier.... 
My recommendation was the Ampzilla 2000 Mono .Blocks

There are a ton of reviews out there, here is 1

How about the Teddy Pardo MB100 monoblocks? Some say they sound better than Naim NAP 135.
