Is the EMM DAC6e or DCC2 /CDSD the best out there?

I have just posted a mini review outlining sonic differences on Esoteric X-01 when powered alternatively by Epiphany and Shunyata helix Python VX. See:

Is the EMM DAC6e or DCC2 /CDSD the best out there?
I think it would be hard for anyone to answer this question, not so much because audio is so subjective, but because there is just so much out there.
I'm trying to pick a handful of DACs to audition and now ARC comes along with a new CDP:
" the Reference CD7 breaks new ground with a gain stage taken directly from the REF3, incorporating the latest proprietary capacitor technology found only in Audio Research Reference components.

Using four 6H30 triodes, the audio stage features high voltage regulation using an additional three 6H30s, coupled to a massive power supply."

The Reference CD7 is indeed excellent but not in the same league as the Meitner stack. My advice to have the best of both is to get the ARC Ref 3 preamp and use with the Meitner stack. This is what I have in my system and I wouldn't trade it for anything. No need for vinyl

OneObGin, have you actually auditioned the ARC CD7?

I used to think it was amazing. Now I just think it is amazing until you listen to great vinyl. My vinyl front end is back & is better. I don't mind listening to Digital nowadays as I did before but the Emm combo is not as good as top notch vinyl. I guess there is room for improvement. Is it possible is the question. SACD is great though & very very close. CD is more distant.
