I'd like to get to the bottom of the science behind this if there is any. If I'm following this correctly, the CD surface treatments improve CDP replay perceived sound quality. However, a rip from a treated disk sounds identical to one from an untreated disk?
In which case, the following possibility spring to mind: The surface treatment makes no difference to the bits received, however a CDP has to work harder to track an untreated disk and so servo noise causes jitter or other artifacts which affect the real-time output of the CDP. However, a rip is never going to suffer like this in the first place since there is no real-time activity as such, we are just moving bits around from one storage media to another. Jitter, noise etc will only appear later when the rip is "played" - by which time the disk and its laser reader have already left the building. Since there is no reliable way of comparing the audio playback quality of the CD in a CDP versus a ripped file via a media player...not sure where that leaves us. For me this is part of the equation that renders CDP redundant, since they are inherently more flawed as a digital TRANSPORT mech than a hard drive. Bits are bits until they hit the DAC - then the fun begins. -- Phil Leigh You want to see the signal path BEFORE it gets onto a CD/vinyl...it ain't what you'd call minimal...SB3+Stontronics PSU - Altmann JISCO/UPCI - TACT RCS 2.2X with Good Vibrations S/W - MF X-DAC V3/X-PSU/X-10 buffer (Audiocomm full mods)- Linn 5103 - Linn Aktiv 5.1 system (6x LK140's, ESPEK/TRIKAN/KATAN/SEIZMIK 10.5), Townsend Supertweeters, Kimber & Chord cables ------------------------------------------------------------------------ Phil Leigh's Profile: http://forums.slimdevices.com/member.php?userid=85 View this thread: http://forums.slimdevices.com/showthread.php?t=44567 _______________________________________________ audiophiles mailing list [email protected] http://lists.slimdevices.com/lists/listinfo/audiophiles
