What the Best Dac have you heard or owned. How could you tell it was that good.

@metaldetektor I was in the room with them. 11-6 and 11-4 Sunday. Sounded great. A sterophile guy came in and loved it. I was the bald head guy.  However I stepped out a couple of times 

Ayre QX 5 twenty. Followed by Bricasti M3. Both excellent, sound, company, support.

Denafrips Terminator II. Upgraded from their Venus II. Also using Iris DDC for USB.

I know it is good since it resolves details I haven't been able to distinguish before. Particularly in low regions. I can clear hear bass player taking several different notes in fast succession rather than just one pick or several smeared one over another. 

@calvinj  I finally gotten around to this thread. I have enjoyed the many post that have focused on your original question, which to me did not seem structured to a price point. 

The best DAC that i have heard is the one I currently have in my system, an Audio Mirror Tubadour III. It provides a smooth, detailed, harmonically rich presentation at a price point commensurate to my system.
