Need recommendation for amplifier


One of my NuForce monoblock amplifiers seems to be irreparable.  I need to get a new amplifier.
 I’m looking in the one to two thousand dollar range, new or used.
Any recommendations for a decent amplifier in that price category?

Tektondesign is the company that builds and sells Tekton speakers so I assumed the owner is selling this along with some speaker cables.
Tim,

I had to leave the house for a few days but left the amp on.
When I came back, it was much better.
I guess I’ll give it the full 45 days before deciding.
Thanks for your interest in this endeavor.
