I've been reconfiguring my 2 systems and bought one of these as a fill-in and when I got it I was shocked. This tiny amp verges on high end sound, due to the two German Infineon MERUS MA12070 power amplifier chips, independently powering the two channels of the amplifier in a balanced circuit, tied to a medical grade power supply and ingenious design.
This is not like the many chip amp designs using re-purposed op-amps which are very clean but weak sounding. The Merus is a landmark chip, a true high performance dedicated power amp chip. It is full bodied, with excellent transparency and dynamics within its pretty generous power output.
Produces an honest 60-80 WPC, and has surprising bass power and dynamics into the 20s.
Guys, this is not a joke. Hearing is believing. I believe the Merus chip, properly used as in this amp, is a real innovation.
I was so impressed I bought another and used them in both my systems, driving both my 86 db $1500 Revel M105s and my 87 db 4 way $18,000 Avalons. These are hard to drive high resolution speakers and the sound is very satisfying.
This guy is dynamic, sweet, spacious and uncolored. Has a sub out and switchable equalization, both balanced and single ended inputs. It is so efficient it has no heat sinks and never even gets warm.
They sell for $200 new plus shipping, but they come out of China which takes a couple of months now. I get that no one in the states want to sell a real quality $200 amp, it seems.

Sonically, it easily outperforms any amp under $700 I've heard, and I've owned a lot of them.
The A20A matched to the Topping E50 dac/pre I'm selling makes a remarkable stack for your $400.
$190 shipped to US.
Thanks for having a look.
