I upgraded recently and decided that it's time to let go of this little unit. I used this on my desktop set up.There's minor cosmetic imperfections along the unit and volume knob. I've tried to take pictures that highlight imperfections.Note: I'd recommend keeping this powered on at all times. When turned off and turned back on, it giltches for a bit where the volume suddenly jumps. If you so happen to have turned it off, just twist the volume back and forth and it sorts itself out. I'm not sure why it does that. I'd also recommend keeping it at max volume when using as a DAC so you won't lose in "bit performance" - basically, just adjust volume on your amp.Otherwise, if you keep it on at all times and don't off the volume, it performs with no problems. I think you may have to install the drivers to work this which can be found on ifi Audio's site.From a smoke-less and pet-less home. Ships from MN.Let me know if you have any questions!
