Delta Sigma DACs

I’m afraid you’re stuck with Redbook layer. Your Cambridge CXU can output digital only as S/Pdif and this format won’t work for SACD.

I don't think that's correct; where did you read that?  The Cambridge site says it plays, among other things, SACD and HDCD formats: https://www.cambridgeaudio.com/usa/en/products/cx/cxu

If it was only capable of S/Pdif, how could it play SACD disks?

Then why do R2R DACs sound better than Delta Sigma?

Then why do R2R DACs sound better than Delta Sigma?

In fairness, better or worse sounding is somewhat subjective and at the discretion of the ear of the listener.

That said, and based on the relatively few delta-sigma and multibit DACs I’ve heard, I prefer multibit as it is more authentic and not as digital sounding to my ears.

Cheeg, Yes, it can play SACD but it cannot output it other than analog.

R2R's don't sound better than delta sigma's. Maybe the MSB, but I never had that in house. I have not found an R2R yet that can beat my delta sigma.
