Devialet USB input

[Antoine]

EDIT:  and another thought.....   I recall Guillaume rated the Melco N1Z a lot higher than I did.  However, I did think some aspects of the Melco's mid-range performance was absolutely outstanding, it was just the bass accuracy I had a bit of an issue with.  However, maybe when Guillaume tried the N1Z in his system, with decent mains isolation kit, the 'leakage loop' issue was fully mitigated, so Guillaume would never have heard the bass issue I did?  (more wild speculation that kind of fits the theory!)

You'd think on kit costing what the N1Z does, that bearing in mind their intended use, these things would be covered in the design of the kit rather than relying on external configuration?

Intona was the first to succesfully implement real USB galvanic isolation for high speed USB (480Mbit/s). The technology didn't exist yet when the Regen was designed and probably the same is true for the Melco's as well. IIRC Uptone is working (or has said they once were) on a new Regen that has galvanic isolation built in. Fortunately we're seeing more and more products employing the galvanic isolation for USB so in time it'll probably become a standard like it has for AES/EBU and S/PDIF. I'm curious if Devialet will implement it on their new streamer board, but i'm pessimistic to be honest.
