As noted above it’s most likely photoelectric effect related. High fields in those tubes with bright LEDs next to them dont go well together.

Yeah a quick google suggests that most pro audio processing tools utilise floating point processing. If that is the case, I'm curious are there really any areas along the processing chain where high bit depth is of any benefit? Providing of course you are of the opinion that the redbook...

  Actually this is something I've always been curious about audio editing software. If you are using a computer, isn't all of the computational processing done using floating point arithmetic? I mean where is the delineation between floating point and fixed point arithmetic along the processing...

It was obviously sarcasm.

Depends on the design, but yes if it's supplied then I would use it.

  I wasn't being serious. Perhaps I should have put a "I won't hold my breath" at the end. :)   That verbose wall of text from Cardas is just about long enough to dissuade most people of a scientific/engineering bent from wasting their time explaining it's nonsense. Quite good marketing really.

Well I'm waiting for any theory, logic or explanation of why cable burn in would happen. Has one been posted?

You can use a little contact cleaner or some solvent that will help slide the sleeve on then evaporate.

He seems to be quite clear of the iPhone's limitations, and is he incorrect about the measurements? From what I've seen on other reviews the current crop of iPhones, and indeed many of the previous ones are quite competent devices. I don't see anything that needs criticising.

If you really like the dt880 why not go for them and apply a little EQ. Job done

I'd  suggest you start here, Volume 2.   http://www.feynmanlectures.caltech.edu/   If it's too difficult try wikipedia.

  Thanks for the suggestions btw. I like stratocasters mod, so I think I'll give them a try. Will post results.

    My previous one was an e7 I think. Similar dac/amp, the display died on that one, along with one of the volume buttons. I'm living on a different continent to where I bought the e10, so I don't think I'll bother trying to return it. Cheers anyway.     Thanks for the suggestion, but...

Guys I need new earpads for my SR125s, they're turning to dust on me. Are there any comfy velour options/mods that are an easy fit? Also where is the best place to get the thickest and softest pleather/leather headband? Cheers

Yes the thing sounds fine, but the whole reason I bought it was to reduce noise. And here I am with a noisy volume knob. This it the second fiio product that has died prematurely on me, and will be the last product I buy from this company. Not impressed.
