    Since the output power is low, class A operation is practical for headphone amps. Unless it's for something that uses MP3 comressed files as a source, in which case it's going to make the sound worse.

    MP3 is a lossy compression algorithm. MP3 files played back through really good audio amps are obvoiusly missing sonic components. It's not really significant with rock, but try a violin solo sometime.

    It also depends on the bit rate, i've been impressed by the quality of some mp3's. as far as the original question headwize.com has some links for headphone amps.
