Unpacked amp, downloaded USB driver and connected amp to my PC via the DAC. Sounded pretty good - changed the USB cable and it sounded even better. Powers my 3 sets of speakers easily. Deep bass and excellent separation on each track even the lowest bit rate MP3s
bass-oriented sound, flat, not dynamic, lifeless sound. tested in studio on many cheap and expensive speakers and everybody was suprised how bad it sounded. it sounds like music listened to with earplugs. you can increase volume but details are gone.
