Changed from Yamaha AS500, running on Klipsch RP160M.
That little beast can drive those speakers. I'm using it as living room apm, not desktop, but still I barely turn it up to 20-30% and it is loud enough. Compared to Yamaha amp, it is cleaner, more analytical - tighter bass and wider/further sound stage (with Yamaha the singer was between speakers right before the wall, with Topping - it is between speakers, but farther behind the wall).
It is really tiny, love it.
P.s. The rated watts are still unclear, even with the manual.
