Hi. There is some debate about the pass xa30.5 driving speakers to a high levels. I have used this amp since its launch and prior to this a X350 power amp which claims some 350 watts output power. What i can say is that both provided lots of power at usable levels. Certainly more than enough volume. Im talking about volumes that are comfortable but loud, not ear damaging loudness thats no use in normal domestic settings. However I do recall the 350 having a touch more slam but not quite the extreme clarity of the newer but weaker model.
