Bel Canto gear sounds wonderful, esp the latest models. I love my REF 1000 mk2 (now M) paired with a Pass Labs XP10 pre. Wonderful combination for warm, open, wide soundstage, excellent detail, dynamics and PRAT, very deep tuneful bass. I hear very good things about the REF 500M too. I can't comment about W4S gear. Tell us about your other components...
