New or Old CD Player?

Of all the things in audio that are improving at a fast rate now, it's probably the DACs.  Your older CD players will have an older DAC chipset in them, so in my opinion, I'd go for "new" in finding a new CD player.

Sound advise

It sounds as if the CD player you bought was the one you had wanted to get all along??? judging from your original question. Good luck! ARC is a great HiFi company.

I auditioned a Marantz SA-10 SACD player this past week.
I am mainly interested in it for the fact it has Toslink and RCA digital inputs.
The Marantz SA-10 does the decoding in DSD, even for CD data.
I am not a big or even mild SACD user.
The main joy if the device is playing back CDs on another machine, and using the Marantz as a DAC.
Redbook never sounded so good.
I AM buying one. Just to play CDs through it from other machines!

I am just mentioning this to say do not overlook SACD machines in the quest for a great Redbook CD player.

2psyop, I was open to suggestion, and still am. The CD8 made sense for the reasons I detailed earlier. But I still have not heard the unit, and that's what matters. If, for some reason, I don't like the CD8, I will sell it and again be in the market for a CD player. Besides, I think its been an interesting discussion thus far.
