Thanks for the input SH.

Active bi-amp? As in separating low-end signal at preamp or integrated tube amp (if it has a “sub out”) and feeding it to “in” of active sub’s amp (SS) with IC cable? Then the other signals go thru tubes and to the main speakers which has tweeter and mid-woofer?

“best of both worlds”, meaning the smoothness of tube for upper range with speed of solid state for lower range? I’m surprised not to hear more people talking about using this set up…

Thanks again.
