If anyone requests Audioquest to terminate a Digital Link cable for Devialet Dual-Mono, Audioquest follows this concept and wires the cable accordingly. Hence, no adapters are necessary.
Audioquest earlier had a problem with their Digital cables that have 72V DBS not passing 24/176.4 and 24/192 from Master to Slave but they worked around it and found the fix.

Can someone briefly explain “ground lifting”? When I googled it, the video that came up, the guy was actually cutting pin1 on the xlr. Is that what you guys are doing? Cutting the pin off your high end cables?

I don't want to modify my cables, so I'm just using an adapter like this one:

Alternatively, on the Slave, disconnect wire from Pin 1 (GND) of XLR plug.

Astonishing effect on sound after desoldering Pin 1 at RCA-XLR adaptor for (D400 slave).
I thought of moving to the SPDIF way for slave connection (being able to use the trigger cable), but galvanic isolation is more complicated then (extra device).
Guess, i will also buy a special cable instead of SPDIF+adaptor.
In meantime i've established means of galvanic isolation for Ethernet-, USB- and slave inputs to great effect.

Haha! I needed to hear this from someone who hadn't tried it earlier.
I/we (some of us here) have been enjoying this for years now!

Well, the sound character changed remarkably, stage is very different, even more pressure in bass.
But it has been a rather short listening session only and i have to wait if i really like all the changes as a whole...
What i'm wondering about:
i cannot remember any hints from reviewers on AES cable modifications (unfortunately i could not (re)find Devialet's instruction for adapting, but i believe they connected Pin 1).
Professional testers attested dual mono significant improvements in sound quality compared to a single unit - why did none of them try the mod?
Or does a super expensive cable with full connections achieve the same results? (i believe - no)
It's such an easy/cheap mod ... possibly saving thousands of dollars.

In meantime i found the sound to be not even unfamiliar but also worse to my taste.
It felt like a huge bowl around each speaker, concentrating to depth only. I also missed the crisp and punchy sound character of the system.
Things became more strange when listening with headphones (pre out of slave connected to headphone amp).
Finally i decided to reconnect Pin 1 for testing and now things are right again in my hearing.
To be honest, i have no idea what happened first w/o Pin 1 connected - i was deeply impressed in the beginning.
I ordered a new streamer which will allow to do w/o Devialet pre out and thus try to settle pure SPDIF connection from master to slave.

If the AES input is being used on the master amp, it is correct to assume that the recommended connection type would be RCA on the master to XLR on the slave?
