I'm in Taiwan with a PCD with headphone. I didn't bring my CDs but the public library has good collection. SONY'S new MZ RH10 has USB and line in (analog, optical). I would think the cleanest signal in would be an optical digital signal from "black box" --sorry I don't know what black-box would be but imagine it is digital signal from a PC before the sound-card turns into analogue. Or the digital feed out of transport before it goes to a DSP. I don't have audio or computer audio equipment of that caliber in Taiwan. If my fall back is using the line out / headphone out from the Phillips PCD, I assume the HiMD will have whatever colorations the PCD adds or replicate the limitations. Are there any other ways to get a more faithful replication of the CD. Many thanks, Richard Moss Taichung 400 Taiwan ROC
