Bought one when I intended to use software DRC in a revamped speaker rig, then a second one for a potential balanced headphone rig. Going with hardware DRC and unbalanced headphone amp, so both need to go.

This one is $165 via PayPal, shipped USPS Priority Medium Box within the US. I received this one in a larger, completely undamaged box as a lightly used unit from a dealer, so I believe that the SMSL box had been damaged previously. The unit works perfectly, though! There is one very, very tiny nick in the faceplate above the H-Res Audio emblem that I didn't even realize was there until I set it in front of the window to take the picture.
