By the way the Gemstone is better than my ADA amp. Great clarity. It really opens things up. I had the emotiva with the gemstone. My meridian and ada are both sold. What was really dissapointing was when I had my friend come over for a listen(he has the best tested hearing of any of my friends) and he said that with the Emotiva in place it was the worst he heard so far from my theater room(oouch). A major downgrade. His reference point is the Meridian 861 with the Gemstone amp. I would agree with him but not that bad. Hell if you think about it the Meridian is way over priced. The sound out of it though is worth it(used prices, never new).
