Virgo II owners: What amp to buy?


I currently run my Virgos with a Symphonic Line tube pre-amp and I'm looking to partner that piece with a new (or used) amp. I bought the Virgos based on a listening experience I had at a Stereophile show in Los Angeles. If I remember the Virgos were paired with a Rowland integrated. I've been trying to recreate that sound ever since (yes, I know I should have bought a Rowland integrated but unfortunately did not). I love my speakers but they can sound a bit bass shy at times and an amp that "rounds" the sound a bit and maybe adds a little warmth would be a good thing. That said I would hate to give up the soundstage and clarity the Virgo bring. Any thoughts?

Excuse my stating the obvious, but why not use a Symphonic Line 7? You have the pre from the same stable... (v.good pre, btw).
Must be some used 7's around!

Incidentally, I once used a 7 on a pair of Virgos to very good effect I might add:)
Think about my Coda-Continuum Unison 3 Ultra ss integrated, selling on 'Gon for a nice price. Smoothest ss I've heard in my home. Plenty of current delivery for bass. Lightly used in a now-dismantled "third" system.
In the past, I was quite pleased with the Pass X-150 and X-250 amplifiers. Very good soundstage and bass control. Of course, as you note, the Virgo II is a little light in the bass overall which can compounded when the Virgos are placed in an overly large room.
If the budget can stretch a bit, my experience suggests the Virgos work superbly with a (used) pair of CJ Premier 12 monoblocks.
