Best monoblock amps for $2000 used

I bought three used Marantz MA500 monoblocks 125 watts for like $300 each and they work excellent.

One of my favorite mono block pairs at any price is the SST Ampzilla 2000.  I have seen these a few times for $2500 a pair. 

I am using an Odyssey Stratos Extreme with the Jolida Fusion Pre and it is a very good combo IMO. Very meat on the bones almost tubey midrange but fast and great bass. I would think 2 k will get you into some used nice used Odyssey monoblocks. 

tinlub, I owned a "Son of Ampzilla" back in the seventies. Great amp as
I remember. Thanks for the memories.

mofojo, I have the Jolida fusion pre, but haven't used it yet. I will look into
the Odyssey product you mentioned. I'm currently using a Jolida fusion
801 integrated amp. Any comment on the comparison of the Odyssey
vs the 801?

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
