Really fantastic sounding balanced DAC. It took a DAC that is more than 2x the price to best this (Mytek Brooklyn +). This DAC is one of the few products that allows for bit perfect selection (native vs upsampled). I have always felt, for well recorded tracks native bitrate sounds best. Lousy streaming stuff, upsample. With this DAC you have the option to easily switch. In terms of signature this has a very nice deep soundstage and balanced sound - it is not warm, or colored, but well balanced, neutral and smooth, though extended in the treble. I will miss it!
I have used this sparingly over the last few years. Smoke free home. Condition wise, I don't see any flaws but rating to be safe just in case.
If interested, for a small amount extra I can include a upgraded power cable, and fancy usb cable.
