No-one having mentioned the Rhea yet, I thoght I'd chip in. The Rhea sounded excellent & seamless with Virgo's. There was no perceptible muddiness and on reasonable recordings the sound of the strings was very clear (i.e. many cellos).
With the Rhea, the Virgo sounded like a much larger & superior speaker with better micro-dynamics and good "volume" on voclas & strings alike.
The usual caveats: I listen & judge by classical; the electronics used in this combo were Symphonic LIne & CAT; the cables were bearlabs IC & valhalla. Cheers!
