Tubes or stick with S/S

I've never seen a tube driven sub, so an all tube pre/amp system (as I have) with one or two (or a swarm) of solid state amp driven subs seems fairly normal, and using 2 RELs with the mains left alone works for me. The tube amp I use is a 12wpc or so single ended thing, and the subs total 250 watts...sounds sublime.

Low wattage SET or other SE amps on those Cornwalls if you really want to hear what those speakers are capable of... Nuff said! 

In my last few systems I've had sucess using a tube pre-amp with a SS amp.You get the bottom authority of SS, with the sonic signiture of a tube.The braun, with the warmth, without the need of expensive power tubes.

Happy listening.

You get the same (if well designed) just by going Class-A solid state.
This is why I suggested to mfdamon OP to look at the new 25w Class-A Schiit Aegir which would have no trouble with his 102db Klipsch Cornwall III’s
