I've just received my Sonata HD DAC Cable II. Since there is no real manual, I was wondering why there are 3 FW Versions for the "old" cable (A, C and D), and only one version for the 2.0 Cable. Which setting is used in SONATA_HD-A-V2.0.zip ? Is it all 3 versions "combined", so best audio...

The volume up button of my DX90 seems to be broken. I can only turn down the volume. Any idea what i can do (other than a factory reset) to raise the volume again? There's no hidden touch sceen volume control, isn't it?

The only hiss i hear with my Heir 8.A is my own blood flowing.:)

Works like a charm on my Win10 x64 Laptop.

Is there no automatic EQ system for headphones yet that uses a microphone? This one (for speakers/room) works pretty perfect on my Yamaha Receiver: https://www.youtube.com/watch?v=MwMsv7-dnpc

  This looks like a good deal:   https://www.amazon.co.uk/Yamaha-HPH-MT220-Headphones/dp/B009F8WRXG/ref=sr_1_1?ie=UTF8&qid=1470076554&sr=8-1&keywords=yamaha+hph+mt220

I owned the HD 600 before and wasn't too happy with it. My personal favourite owned headphones list is as follows (sound quality from best to - not so good).   1. Yamaha HPH-MT220 2. Focal Spirit Pro 3. B&O H6 4. Heir 8.A CIEMs 5. Bowers & Wilkins P5 6. Sennheiser HD 600 7. Sennheiser HD...

If you accidentally formatted the internal storage of the DX90 on your PC (happened to me, too ;) ), you need to reflash the device using the iBasso Batch Tool. Download and Instructions...

From what I understand the gain doesn't affect the (non amped) line out, only the amped headphone out.

I had massive problems using it as a DAC on Windows 8 or 8.1. Simply wouldn't work or stop working after a couple of seconds. Since I upgraded my Laptop to Windows 10, the DX90 DAC functionality works like a charm.

Actually a new line of headphones:   http://www.focal.com/headphones/

Just wanted to thank the support team at iBasso for fixing my DX90 although it was out of warranty. I got it back today in perfectly working condition.That's what I call excellent customer service!

It's just always funny when someone here is talking about a headphone's "soundstage" who probably never had the pleasure of experiencing a decent pair of stereo speakers in a proper setup.

  I have the same problem as you, but with the headphone jack. Unless I push and hold the headphone plug in a certain direction, the left channel is off. Since my DX90's warranty has expired I decided to give it a go and try opening it. Here you can see the headphone and the line out jacks. I...
