Ok well I made a decision. I ordered black lumin u1 mini, modded by dealer to accept dc power. Ordered Keces p8 to power it and finally DI20HE to be after the u1 in the chain. Will try all different combinations like u1 mini alone, di20he alone, also compare the u1 mini to my pi4b. Will sell whatever doesn't make much of a difference. Hopefully this all works out well. Plan is to go BNC from u1 mini to DI20HE and then i2s or AES into dac.
I really was interested in the soundaware but the lack of reviews made it tough to choose.
