Thanks for the response guys.
It's actually quite scary how the cable disintegrates almost naturally. It's my third beyer T5p it's happened to. Putting it in context; the most experienced headphone manufacturer out there and this is their (joint) highest priced product. Oversight or what.
Still in contact with polar audio, beyers registered dealer in the UK - want to know the exact cable they'll replace it with.
I Was thinking though to send this headphone...
''I tell you, dacs and players have dome a long ways in just the past couple of years.''
Agree completely. Have for the past week or so been listening to the hrt microstreamer and the audioquest dragonfly II (which I've got now), and they both perform a level at least above the audinst / O2 ODAC
So just got the DX90 and I'm really impressed. Like the amazon reviewer said, it does sound good with these T5p's.
I updated the firmware pretty much straight away and this is how I did it:
1) Downloaded and unzipped the firmware off Ibasso's site (in their downloads section).
Thread starter provided the link in the first post: http://www.ibasso.com/download/DX90FirmwareV2.0.5.zip
2) Followed simple instructions in the Readme file in the firmware...
