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.

Several good suggestions made here. I did not realize there were so many good choices for under $2000.
Please let us know wat you decied to purchase.
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?
