Topping bested only by the Benchmark AHB II. I love my Benchmark, but bought a different variant of the Topping circuitry, 150 watts into 8 ohms, for my studio system, and it just kicks butt. Buying amplifiers by the pound is soon to be a thing of the past.
"Conclusions
It is abundantly clear that ton of great engineering has gone into the design of Topping PA5. It breaks all barriers as far as noise and distortion, not only in its own budget/desktop class, but way, way outside of that. If it had double the power, it would obsolete all of them and in a hurry! As it is, I would certainly use it in a desktop or secondary system. And even primary if you are not going to blast the volume with super inefficient speakers.
It is my absolute pleasure to recommend the Topping PA5. The dynamics of stereo amplifier market just changed folks!"
