From Denafrips Pontus to Lumin

@paoz  I'm using USB, only because I was already heavily invested in it and have optimized around it over the years.

If you have a choice, I2S is excellent as well as being a much less 'pricey' path.

I use the Innuos Zen 3, as a streamer and hard drive to store my CD’s, into a Denafrips Iris DDC and then i2S from that into the Pontus. I love the Denafrips sound.

@paoz what are you using for control app? Would you use Lumin app via UPnP if you make the switch? 
Asking because while I preferred the Lumin app over many other UPnP/DLNA options, changing to Roon was a revelation UX-wise. If you are considering similar, that might affect your decision on the hardware. Cheers,
