Audionote Soro SE, or cheaper single-ended?

Thanks very much for the info, Howard! I'll do a lengthy write-up of the show if there's anything I hear that really interests me. This is a bit more mainstream than the stereophile shows usually are. Whole lotta home theater and crappy solid state. But there's also some stuff there that I've always wanted to hear, like Lamm, Wilson Benesch, Harbeth, etc.

off topic a bit - Any suggestions on what tubes will warm up the AN Oto se?

I have an Oto SE, and in my opinion it is a pretty warm sounding amp out of the box. Mullard EL84s will sound warmer than the stock tubes, but IMHO there is also a loss of the pleasant clarity and timbre or grain to the music.

I have tried new tubes in almost every position, and the amount of change they bring to the sound varies from a lot (EL84s) to almost none (6922s in the phono stage). I have had good luck with CBS Hytrons and (surprisingly) with Baldwin 6BQ5s; which are still quite a bargain. The latter are hard to find matched, but they are cheap so buy many and match 'em up yourself.

Can oto se, push 86DB Scansonic mb2.5, I don't want to shake the floors and neighbors windows?

I Want tube amp which doesn't make big hole in pocket when rolling the tubes, and also I want to last for ages...

frankly I doubt it, the impedance says 4 ohm so not tube friendly in that department either

just my guess
