Hi everyone, I'm looking to upgrade and need to sell my current setup. The concero was purchased a few months back from a fellow head-fi'er. Comes with original box and Apple remote. Remote does have a small dent on the right side, but performance is uneffected (see pics). This dac is used by several reviewers for it's transparency. Aune x7s was purchased from Massdrop back in April. It's the silver edition, and I have the original box and all cables. It's a great way to get into class-a amps and has a balanced out for all the power you'll need. (*amp is sold*) Looking for $400 for the DAC, obo.
