Mitch ... the CD-6, like its bigger brother, the Ref CD-9, has quad chips in mono mode, or something like that. I believe the DAC 8 has a similar topology. Aside from the topology difference, the CD-6/9 can upsample and supposedly has a broader bandwidth. Most redbook CDP have a brick-wall 20K Hz filter.
While I appreciate the CD-6's added flexibility regarding its DAC and ability to decode different digital formats, I wonder if the quad mono chip (or whatever) topology relates to the playback sonics of the redbook CDP functionality. Stated differentlty, I wonder if the CD-6/9 sound better than the now discontinued Ref CD-8 in redbook CD mode??
If anyone has been there and done it, I would appreciate reading your reactions and comments. Thanks.
