Any US manufacturer of a 845 SET amplifier

@danager thx those STL amps with OTL design look fun and intersting. That Dr D guy on YT is quite giddy about Alans creations it seems.

@mesch looks like you are set, literally, no pun intended LOL. I think id like that Transcend amp you have more than my prior Inspire Hot Rod.Will look it up.

@atmasphere Ypur kind response helps me, alot. Thank Ypu for your time explaining and writing that up. It is similar with "bandwidth" discussion I had with Luke Manley at VTL. Maybe I should appreciate what i have right now even more. 

Back to listening. Happy Holidays to all of you.

@danager I have a lower model STL hybrid that uses KT150 tubes, and I agree with your assessment, I'm using mine with apogee duetta 2 speakers and the bass is great. The hybrid amp doesn't have the power of my Krell amp, but the bass is more detailed and the midrange is better. 

@decooney My Transcend is an earlier model which I bought used. His later version has similar circuit topology with higher grade parts. Aric can build/modify to ones desire. A fine person and easy to work with. You will enjoy your conversation with him.

Thanks @mesch, I’ll be keeping an eye out for a 2nd smaller form factor stereo tube amp I can rotate in while leaving my pimary QS Mono 120s in place, saving these.

Contemplating with some reservations about selling off a good chunk of my vintage NOS tubes and my Pass/Forte’ Class A SS amp and preamp system I had Jon Soderberg upgrade for me. He’s 10m from me. Can’t seem to get myself to list it all.

This would help fund a nice EL34 amp I could rotate in so I can save the QS monos for a long time - they are extra amazing with the specific mundorf coupling cap, nichicon power cap, tube upgrades. Amp2 forthcoming. Will take a closer look.

One of the best on market: Alexus audio 845 monoblocks 2x845(parallel) class A 55w at 8 ohm. each
