http://www.avguide.com/article/news-pass-labs-introduces-class-integrated-amplifier?src=PlaybackI want this amp. BAD. Nelson's son Colin told me XA30.5 would be enough for the Ushers, but I didn't believe him. Now I know he is right. It makes 60W+ into 4 ohms pure class A, and 110W AB. Built in preamp and remote, oh yeah. Only dissipates 200W, cooler than my tubes.
