Replace CD player or add DAC?

The sourse is the most important part of you system. Depending on how much money you have to spend on a DAC look at MSB Tech the Gold linkIII is good at round $850 but for twice the money the Platium Dac is the way to go. Used it will range from $1800 to $2200 but you will have the makings of an unbelievable system.

Keep it all, buy a pothaudio.com non-OS dac for $175. Plenty left for tweaks, cables, music and sanity. Speakers next, good luck.

Thanks for the insightful insights.
I have all the cables and music (over 1500 cd's), so improving the enjoyment/musicality of my listening sessions is my elusive goal, you all are familar with that slippery slope eh?
I'm thinking the Cary 303/200 CD player for around $1700 - although I like the idea of tubes somewhere in the front end, I'll have to wait until I upgrade the preamp, and go with tube's in that. But before that, will prolly kick the speakers up a notch... I'm struggling to avoid this upgrade addiction, once you hear your system make magic, the devil on your shoulder says more.. MORE.. MORE!
So, it seems we're saying the Cary 303/200 would sound better than Marantz CD67SE with a Trivista dac in this humble rig.

Tubes in the front end have certainly sweetened my system. A Jolida CD player can be had for under a thousand, or more for the fancy upgrades. I have one of each and can hear some difference, though it is not too great. A Palette preamp also would clean up the sound, frequently for less than 900 on Audiogon. Lots of fun, don't break the bank.
