In many rooms and depending on typical listening levels I suspect it is enough power, but there will be times in some settings, with some music, when it might make you wish you had the XA-60s. When it comes to the Pass line, I would by the amp with the fewest watts that are sifficient, I just think the lower the wattage the better the sound, IF, it is enough to drive your speakers. The XA30s are borderline and I can understand it being a difficult decision which, unfortuantely, you can only find the answer by trying them in your home with the music and volume levels you enjpoy.
