I ordered this DAC together with the Topping P50 linear power supply. I have also a Toppin D90 (AKM chip) DAC in my living room and bought this for a smaller room.
Compared to my D90 it has a more analytical 'cooler' sound. I like the D90 a tad more, but that is a matter of personal talste. Also the D90 was much more expensive. This is still a very good DAC for the price though. Therefore I give it 4 stars.
