I am a big fan of Nelson Pass, but his Class A amps put out LESS as the speaker impedance drops. Check the specs on your speakers and see if the impedance drops, especially in the low frequency region. Any drops below 6 ohms or so will work against the Pass amp. Too Bad! You might check out the Strake Sound AD4.320. A great amp (check Google for a review by "Home Theater something or other") and it's on sale at 40% off for Black Friday. I just ordered one. Over 200 wpc available for Stereo into 2 ohms!
