Tube Amp with tone controls for Heresy IV's

Not just finding them but for 3K or <  that sounds good too. I don't know of any integrated valve amps.. Sansui maybe, if you can find a good one to rebuild..

I'd say it's going to be an older unit, if at all, for me anyways.
New, not gonna happen, used if it's older an probably rebuilt, for my taste.

Separates, no problem.. ANY older tube Mac pre any older Mac valve amp.. They will work.. Actually made for Klipsch, JBL, Jensen and Altec.
BUT you gotta have GOOD tone control.. Not just tone control.. I like Macs, loudness, bass contour AND tone control.. all of those features (C20) make a Mac very versatile.. Takes a lot of the "tube rolling" crap out of the mix too..

That good to know, and pretty reasonable too.. I just looked at that.. El34s. Not for bass duty, sorry... that would be a no go for me. 6L6, KT88, or 90s, IF I had to do bass duty too..

I run Cary V12R at 100 wpc and EL34. They work perfect for me 60 hz and up. BUT I use them at 300hz and up.. Just a perfect valve for mids and highs...BASS not so much.. 60 hz and up will work though..
