Gregm, are you aware that the Pass XA30.5 is not a 30 watt amp? It switches to A/B operation at 30 watts and per Stereophile measurements doesn't clip until it hits 130 watts into 8 ohms and 195 watts into 4 ohms.
Here is what Pass says about it on their web page:
XA30.5 30 Watt Class A Stereo
A spectacular stereo amp with speakers above 87 dB / watt / meter sensitivity. Performance and satisfaction well beyond what its specifications would indicate.
