Clayton Audio amps. I had Quad USA monitors and Gradient subs and was using a Conrad Johnson tube amp to drive the Quads and Clayton M-40's to drive the subs because of their superb control. Then one day, don't ask me why, I tried using the solid-state Claytons on the Quads. I sold the CJ's without ever hooking them back up. Now don't get me wrong - I love tube gear, especially Conrad Johnson, but this little solid state wonder was more musical in what is traditionally tube-only territory: Quads. I haven't heard M-70 monoblocks, probably even better.
