Frankly, a Sony 300 disk changer is probably a better transport than your old 1986 CD player. I have a 300 disk changed I have used as a jukebox for commercial recordings plugged into $3k+ DAC and it sounds great. Not as good as my great Audio Alchemy transport, but it is beter than some older CD players I have had in the past.
2nd question-Mid-Fi DVD/CDP Carousel + Good DAC = ????
For convenience and disk storage limitations , I'm considering replacing my old dbx CDP with a 300-disk carousel DVD/CDP with coax output (Pioneer or Sony) plus a good DAC. Will I give up any significant (keyword) sound quality over a single disk CDP? Will the DAC affect DVD sound?
