Actually, now that you mention it, a touch softer/supple with mine too. Probably cos I tangle it up sometimes.
M-13, you've got the Dx90 and the x5 right. I was waiting for ibasso to patch it up completely (usb dac to work on 64 bit systems for example), but will be getting one soon I reckon. Might get the x5 too.
Anyway, can you provide some sort of comparison between them, with the sig pro please?
If you have earlier in the thread, can you point me to it.
