DAC - DCS Bartok or the new Berkeley Alpha DAC 3

Looking for a dac trying to decide between DCS Bartok or the new Berkeley Alpha DAC 3.

I will not be able to hear them before I buy so I am looking for general thoughts.

They will be paired with MC462 and C22.  I have Revel 228BE speakers.

I am also looking for a streamer that can do multiroom with out roon.

Currently considering Bluesound node or Moon MIND2

Thanks
