Purchasing this power amp has delighted and astounded me, with it's performance. Wonderful power with a complete lack of distortion drives my PMC Twenty5/23 floorstanders with ease, I have not heard them sound so good. I prviously used Quad Artera Stereo and Cyrus Stereo 200, this surpasses them both. It is very transparent and highly resolving which was an issue with some music, so I switched my speaker cables to DNM Reson which is a revelation with this amplifier. Clarity, power, with a capability far beyond it's price.
