Indeed, even if this was the best sounding headphone amplifier ever created, that volume knob would make me sad every time.

Is that an actual analog volume pot? Hope it's not one of those tiny deals and it's a relay.. what a massive design blunder.

The tiny volume control is one of the most basic errors I have ever seen in the user interface of an electronic device. I don't understand how a company like SMSL could have let this product come out with such a glaring error. Perhaps cost reduction has gone too far?

IMO you've captured the Chord look nicely. Was this very expensive to build?
