This dac continues to impress me. This morning I did the first upgrade, replacing the cheap electrolytic output caps with Northcreek Zen 3uF metallized polypropylene. Fortunately the case consists of separate metal panels for the front, back, sides, top, and bottom, so it's easy to take it apart and work on the circuit board without having to unsolder any connections. The parts on this board, like most digital components, are small, so it was good that I used caps with stranded leads. I was able to cut all but three or four of the individual wires that form each lead, and even then it was hard to get them through the tiny holes in the board.
I wish I could say I hear an improvement, but it's so hard to tell that I will just rely on my faith that a quality metal poly cap sounds better than a 50 cent electrolytic.
