Get a DAC for CD63SE or a new CD?


I have upgraded my downstream electronics and would like to upgrade my primary digital source. Would it be better to upgrade my present CD or consider a new CD. No phono input and no plans to go HT. Thank you for your opinions and advice.

It seems that I'm the only one pointing at a complete new (or secondhand) player. As Dwright already mentioned, there are some problems concerning external DAC's, especially with adequate, but nothing special, digital outputs on your Marantz (I own a CD 63 KI, so I know what I'm talking about) and no possibility to lock the two internal clocks (player and DAC). If you like the sound of Marantz, go for something like the CD 17 or CD 17 KI, perhaps looking for secondhand players. Other alternatives include something like a Rotel RCD991, or the gorgeous looking NAD S 500.
Unless your CD player's transport is worn some, you still couldn't beat the DAC-1 with a player of similar price, even with problems of jitter. Have a look at their website: www.belcantodesign.com
You should get new CD player! I mean, used first rate CD players arent that expensive any more...i would have to suggest Linn Mimik or even better Linn Karik, for the money, you can not find better unit.
I want to thank all of you for your thoughtful input. My inclination right now is to go for a good CD, perhaps a dealer demo or good used one. 63SE's are not worth much in the marketplace, I'll just keep it as backup, or give it to my girl friend if her Onkyo craps out, which I also gave to her. Thanks again and be well. Sheldon
