Which model? I have not heard much from them so far...
I am currently using a Clip Zip for portable usage and a Fiio D03K or UD100 for desktop usage. Would really love to just have an all-in-one solution too! (Since the Clip Zip is starting to give me strange problems)
I don't think I can find a J3 for sale here anymore...
Actually, they pop up on the classifieds every now and then.See? (Although I'm not sure if they're sold or not). (Click to show)
The J3 doesn't have a USB DAC function though. For an all-in-one solution, off the top of my head I can think of the FiiO X3, DX50 or DX90 when iBasso enables the USB DAC capability. I don't like AK products so I won't be recommending them.
In that case yup as it's been discontinued some time ago. I recommend the DX50 over the X3 as the sound UPgrade (not sidegrade imho) is worth it for the waiting time.
Confirmed by iBasso apparently. Don't remember which post exactly but I definitely remember seeing it on their website.
I have DX50 and HD600 paired together atm, best results with high gain. To be quite honest it sounds really decent.
Really brings out HD600 treble detail, bass is solid. Not bad at all.
If you're using high gain, I don't think you'd need an amp (although improvements can be probably be had)
