You can find many more DACs in your price range new or used that will provide more value to you soundwise than a CDP. Check out the non-os DACs which typically can be found for $500 - $1000, new.
cdp vs. dac
Going with new system. As of now I know I will be using merlin tsm-mx for 5.1. Unsure of preamp I will be using, but will retain my cary cinema 5 amp. My question is should I buy a good quality cdp and go directly into my pre, say a $750 used cdp, or keep my sony cd/dvd and feed into a quality dac, similar price?
