I added a ton of pictures, so as you can see both are in excellent condition. HD600 works beautifully, it just doesn't get enough use. I'm selling the D6 because it's a bit of overkill for my HF5's. It's a really good combination, and because the D6 is portable, you can use it anywhere in your house. The HiFlight Topkit of opamps and buffers is also included.
(I fixed it)The only problem with the D6 occurred while I was taking the top plate off to take pictures. I was putting the screws back in and one snapped. It's stuck in there pretty well. You can still change opamps via the front plate though, and extra screws are included so if you want to get it out at your own risk, go ahead. (I fixed it) It came to me via this posting. It's still in perfect condition except for the screw. Also includes AC adapter for charging and leather case.
I would be willing to trade the whole thing, make me some offers. I'm looking for a smaller, slimmer amp/dac, and some closed headphones.
$230 for just the HD600's and case. $230$215$200 for the D6/Topkit.
iBasso D6 still available! WILL TRADE FOR YULONG U100 OR SIMILAR.
