Devialet USB input

[Hifi_swlon]

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 ....

It did at the point of the microRendu design though.
That said having now looked inside the rendu and the Intona, it's obvious who are leagues ahead in circuit design so maybe it's far from trivial for anyone outside that specific field - the Intona board looks pretty complex.

I'm too much of a layman but I can't quite see why the same technology used on an Ethernet connector can't be used on USB? The Intona seems so complex by comparison.
