I have a pair of Primaluna Dialogue 6's that I use as monoblocks in my main system, and I use them to drive B&W 805 speakers. The Primaluna EVO 300 and EVO 400 are successors to my amps. I listen to mostly accoustic jazz, accoustic blues, and classical, but I listen to other things too.
I usually listen in ultralinear mode, but I sometimes switch over to triode when I listen listen to early jazz or blues because people would have used triodes when those songs were recorded. I do this whether I'm listening to the original shellac recording, or a reissue on vinyl, CD, or streaming.
I also use a Pathos Inpol Tube Hybrid integrate amp in my office system, and that is also in triode mode. I'm happy with the results from that amp as well. That amp goes for just under $12K, but I was lucky enough to get a used one for a little over $4K.
