I really love my NL-12; it may very well be my amp for life, I believe. No heat, extraordinary bass, very natural voices, unabrasive but detailed midrange, non-tizzy highs, nice depth. It just gets out of the way. As good as Lamms I have heard with my same speakers (Kharma 3.2s) with superior, tighter, more absorbing bass.
I used to have a Pass X350 (for 3 years); the Pass had nice mids/highs, but strange forced, foggy, upper bass. Lower bass was deep & detailed, though, but heat was a big prolem. They have a 30% off sale at Edge for a couple of weeks.
