Not many reviews though... Comparing this amp with today's new arrivals... the only think i can say who ever buys it, it will last another 20 years the minimum. I compare it wit Cambridge Audio 851W and it wins for dynamics, stereo separation, warmer sound, and most important more reliable by far.
Any reviews will be appreciated
