Pass XA30.5 enough power for Wilson Sophia 2?

My speakers are Focal Electra 1037BE. They are more efficient than Sophia at 93dB/W/m. I often turn up the music to +90dB in 15 x 20 room without any problem. The needle that indicates bias current rarely moves past 12 o'clock position.

Good one 61!

I have a Pass Labs XA30.5 currently driving a pair of B&W 802Ds and it drives them OK. I could use a little more power but the 802Ds have a very steep impedance curve. However the midrange and highs are glorious and the bass is very deep and tight. It just not play as loud I would like at times. It can get a little loose on some passages. The Wilsons are much easier to drive than the 802Ds and the impedance curve is not near as steep. The XA 30.5 is the finest amp I have owned sonically speaking. I am barrowing the 802Ds until get my my Apogee Divas redone by Rich Murry at True Soundworks. I will be selling the XA30.5 and purchasing a set of Pass Labs XA100.5 monoblocks within the next month or two.

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.
