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

The Weiss Dac 501 is excellent. So are all their products. The minute it was on was a wow. (The 501 is also a Roon endpoint.) That's how I knew.. or was the streamer or something else?

The Grimm MU2 (I have not heard yet) looks to be an excellent one box solution. 

For the kind of money needed to acquire upper DAC's and streamers for a fraction of the cost room treatment and vibration control would be more revealing. Then the DAC, streamer or sound would make yah quake.

Nobody looking at T+A?

Playback Designs MPD-8.

It simply plays music at the highest level of enjoyment.

I no longer think about anything but the music. It's the last DAC I plan on owning.

OP, you work for Infigo Audio. Bit disingenuous (but par for the course here I suppose) for you to ask your question and then answer with the brand you work for.

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.
