I've owned a Pass Labs XA30.5 the last couple of years.I like it mainly because it got me off the amp merry go round and had great synergy with both my vintage KEF 107s and more recent Spatial Audio M3s. The only other amp that came close to the 30.5 for me was the Rowland Model 2 (another lower powered amp).
I tend to lean towards higher quality watts than quantity and the 30.5 offers plenty of quality.
