I have finally opted for the DCS Combo (Purcell+ELGAR). The results are outstanding and far outperformed the DAC64. I did not have the chance to listen to the Blu, but I am very happy with my Mephisto + DCS combo. Note that the digital cables play a critical role in this setup. I finally chose Tara Labs the One: perfect neutrality and all the details without an inch of agressivity. Thank you all for the input.
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!
