I also heard the Aria Monoblocks at Johnny R Audio Connection. The system it was in was quite modestly priced, but it put many much more expensive systems I have heard to shame. Out of all the different systems Johnny R played for me, I was most mesmerized by that modest system. Of course, the expensive Proac speakers I heard with a very nice amplification system was quite special as well, but the Aria system really sticks in my mind.
