There is a view that the CDS range of CDPs have an analog presentation and the CDX range a digital type presentation. Leaving aside the power supply question, the core question is really which presentation is more to your taste - analog or digital?
Not sure it is that easy - I know I had it explained to me countless times, but I can't classify musical presentation as analogue or digital. I can only say which I prefer in terms of getting me closer to the music. Of the CDPs I've heard long enough to form an opinion my rating would be (with the last being the best)
Yamaha CDR-HD1300 as a player (fantastic recorder)
Assuming that my list is accurate, I couldn't say I preferred a digital to analogue sound or vice versa
. I just know that as I move down this list my perception is that my CDs get me closer to the music. The only caveat is that I can't really say the Saturn is better the CD5X - they are different, but I like both equally. The only CDP in the list that I think is dreadful is the first one - all of the others give good results - understatement - the last three give fantastic results.
Other people's rankings of the same units might well be nothing like mine - so the only way is to audition and let your ears decide.
My guess is that the Rega Saturn is the most analogue sounding CDP on my list, but it is not the one I'd take if I could choose any. The TEAC VRDS-10 is probably the most digital sounding CDP on my list, but it is not the one I'd take if I could choose any.
Digital - sounds quite unlike Rega TT
Analogue - sounds similar to Rega TT
My classification skills are sadly lacking I'm afraid.
BTW the first CDP on my list reminded me of the sound from an old TT I used to own and was glad to see the back of.
