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

I owned many Ayre products -Codex, QB 9 Twenty, as well as much of the Schiit line. I got very lucky and scored a Brinkmann Nyquist II used. 

The QB9 is plenty good, but the Brinkmann is just has that little bit of clear sparkle. I honestly didn't want to spend that much, but got tired of just making little jumps up in fidelity. Now I have my grail DAC.
