I’m selling this unit for a friend and I have the unit in hand. It has a swirly superficial mark/rub on the top near the rear and the front right corner edge paint seems to have rubbed off a bit (see pictures). Otherwise the amp looks great and performs wonderfully.
It’s the quietest headphone amp I have ever heard and there is absolutely no grain at all. Vocals sound very inviting and the extension/resolution is out of this world. You will not be disappointed. 6Moons did a dual write-up and both reviewers loved the amp enough to give it an award.
