Lumin U1 vs Lumin U1 mini + sbooster?

others who have tried the di20he + streamer (even something like pi) have found it to be better than dcs bridge

Was having an i2s input on their dac a prerequisite or does the di20he have the same goodness via its spdif output? I ask because my streamer already has an i2s output but my dac has rca coax, optical & usb inputs only.

I got good results with AES out of the DI20HE also. But I2s just took it further. Im also only using a basic 8k shielded amazon HDMI cable. Still waiting for a better wireworld chroma cable.
But you'll definitely feel most of the benefit with AES.

Thank you for the quick response. This is the first I'd heard of the DI20HE and your comment of pi and it to be reportedly comparable to the dcs bridge really got my attention. I've been considering the DCS nb or a u1 mini and now a di20he but it might just be a sideways move in my system as I'm pretty sure my streamer (sonore SSR) has a great built in LPS and sonore paid special attention to the spdif implementation with a separate board for it if I remember correctly. I'll ask the manufacturer if my DAC can be retrofitted with I2S, if so,  that might be the way to go for its simplicity. I've read much about I2S sounding the best, of which the SSR has that output.
