Amps for Virgo : TUBE or SOLID?

I have owned Virgos for two years and run them with Pass Aleph 2's (single ended, Class A, 200w into 4 ohms). They are out of production but still available used. I have also heard the Virgos with Classe, Krell, VAC and Audio Research, among others and nothing comes close to the Pass Aleph Series amps with the Virgos. I don't know what Immedia (the importer) uses for amplification, but they used to use a Pass Aleph 5 (65w stereo) with Virgos themselves.

For sheer resolution, I am in complete agreement with Arahl. I don't think I've ever heard higher resolution than the pass labs/nordost/virgo combination. I sometimes preferred the 'aliveness' of the arc equipment, and sometimes the clarity of the pass labs. A problem with the pass labs/virgo combination is that it would expose every weakness of a recording. You could actually hear a singer picking up the mike or brushing their hair. Classic combination. My favorite solid state setup. Not everyone's cup of tea though. This amp/speaker combo was a little lightweight compared to pairing the virgos with the mccormack dna1 or the spectral 180.

Symphonic Line is the amp/pre you want. They sound great together. I do not know how easy is to get that brand in US.
