Counterpoint SA 4s

I got a pair of SA 4 amps and am not sure if they are worth keeping or posting on here to sell just because they don't seem like an amp that is made to be used in a main system. I was hoping a possible owner could chime in and let me know their opinions or someone that has heard them used. I am not even sure what speakers to run with them as Electrostats are not possible in my soundstage

I used to be a dealer.The SA4 is an OTL design, so it weighs a lot less than a regular tube amp. Its a good sounding amp, but OTL's tend to give more problems so that's why you see so few of them. If you're really happy with the way they sound, keep them. If not, I would get rid of them.
