I also have the Chord DAC 64 and have been very pleased. I still believe its a bargain and made a big difference in what was already an excellent system. But I too wanted to experiment with another DAC. I purchased a second hand, mint dcs Elgar and Purcell and am glad I did. It's more refined and not as agressive as the Chord (especially when the buffer on the Chord is all the way up) Just my two cents. See if you can audition the dcs gear at home to see if it even makes any difference in your system. It might not be to your liking. In my system it's a thumbs up.
Looking for an outstanding DAC
I own a CHORD DAC64 connected to an Audiomecca MEPHISTO II-X transport. But I feel I could get more out of my transport. Looking for a 2nd hand DAC (Therefore EMM DCC2 is out for now). I also don't like tube electronics. I am hesitating between a DCS Purcell+ELGAR combo or a Weiss Medea DAC. Any recommandations? Thanks!
