Playing mp3 files from numerous sources including downloads from Amazon, rips from .wav files and CDs, swapped grey market files, home studio generated files ALL play fine on the following:
WinAmp or WMP on XP PC
CDeX
n-Track
Tascam DAW
CDR mp3CD
DVR mp3DVD
Sony NWZ-e438f
The same files ALL play slow and off pitch on the following:
Sansa Fuze
Sansa Clip
It shouldn’t take a $12000 turntable to get reliable playback (and at that price, by the way, I wouldn’t take 1%, either.) When you spend your life loving and pursuing ‘the sound,’ you don’t accept sub-standard reproduction. If everyone accepts this type of fault, another nail in the coffin of art appreciation will be set. Think of it as selecting a color of paint or fabric for your living environment and finding that the manufacturer has decided that they can alter it to simplify their offerings to you.
My advice:
Don’t accept substitutions for the sound you expect. Demand accurate reproduction.
