The build quality is excellent overall

It’s able to push 300 ohm headphones, not sure how much higher though, and provides great audio quality along with good amplification

And the feet sit flat and are good quality rubber that doesn't slip

All in all, I really love the build quality and wish it would work with my system, because my motherboard produces static which the DAC eliminated entirely (while the mic was unplugged)

ive had it for like a month and its great quality and boost but the switches to change between usb coax and optical is messed up

Sound quality is fantastic

I got this to decode optical audio from my TV as well as to power my Sennheiser HD600 and Etymotic 4 series headphones
