Wait, seriously?  I mean, did no one find the following a bit telling:

It happens consistently (and repeatably) at the same point in the song... and it happens in both the left and right channels (c'mon, spontaneous failure of the same nature in both drivers?)... and frequency sweeps don't highlight the issue at all.  It all kinda points to there being some kind of fault elsewhere in the signal path right?

 

Just sayin' - probably not a messed up driver.

I doubt its the driver... if it were, you'd hear distortions or "artifacts" in other recordings or in other parts of the same recording.

A lot of driver issues come and go, and can change their sonic charcter with volume levels.  So if the anomaly exists at all volume levels, and increases amplitude with volume (as though its in the recording), odds are its not the headphone driver.

Dropbox that track for us to listen, to see if it's a bad file.

could the crackling just be the volume at that level?

Yeah, I agree with that, and that's why I wanted to point at the track itself as being botched - but if Logic isn't showing nasty peaks over those samples, then what else is there to point at? If it were the player/decoder the issue would "move", if it were the amplifier/DAC the issue would be more random, if it were the driver the issue would be more random, etc. Let's see what the dropbox'd track shows though.

*EDIT*

Fantastic - nothing opens M4A garbage. GRRR I HATE NON-STANDARDIZED THINGS.

No but seriously, I can't help you because I can't access the file. VLC playback has very slight distortion around 5:35, but nothing disgusting - file is probably just bad.

Thats just how it was recorded.  Pages guitar on that track has been that way for nearly half a century.  Its such an appealing tune in so may ways though that its "flaws" are often over-looked.  Its those little subtle under-tones that give the tune its character, charm and is partially what makes it unique.  I haven't heard that tune in nearly 25 years...LOL

ah right, that'd make sense...

just like the quack in some of gibsons les pauls' guitars... i guess its a personal trait never really thought of it that way, pretty neat.

Yup crackles here too, but it also does on my ZoSo CD and on the Mothership CD, like kramer says it's in the recording.

I just never noticed it before... Now I suppose that's all I'll hear in the future when that track gets played... biggrin.gif

Well iTunes will open it... tongue_smile.gif

Fubar2000 plays it as well, native support for ALAC for quite a while.
