sweetest sounding ss integrated

I would also throw in the Pathos Logos or Classic MK II, although for large scale you may want to get two classic's (something not uncommonly done).

In my opinion the sim gear isn't as euphonic as it is revealing and transparent.

Plinius 9200 is pretty warm sounding. I had one for a little and thought it was a pretty nice unit, especially since it's a complete package, so long as you're not a phono stage freak.

The BAT can sound very lovely, depending on the setup. The supertube version sounded euphonic when I heard it (with Verity speakers) but the SS version wasn't for me.

Old Rowland gear, like the Concentra, get's referred to as warm, but not nec. my experience with all rowland gear.

I have the Pass INT-150 now and it's quite organic, but don't think it's coming up used yet, and don't know about for that price. Still, worth checking out, if you are around a pass dealer.

I would think one of the Unico hybrids or a Pathos Logos would be a goo direction, especially given the listening preferences.

I would second the YBA Passion recommendation. If you're listening to lots of orchestral stuff, you may want something with bigger power reserves, but it's a very engaging amp.

I personally think the Blue Circle stuff is overpriced, considering its build quality..
