Trigger cable is not required; this is useful when using a real companion. The only cable required is RCA_OUT - RCA_IN or RCA_OUT - AES / EBU.
File comparison:
- The MASTER file is not changed at all.
- The COMPANION file (second master in workaround) is completely changed. Basically, it is identical to the one from MASTER, but with a different audio channel (left/right) and another audio input.

@audio_engr - in doing this, did you change anything else? Were you only using the master previously as input? Using a trigger cable?
Did you change anything with the way the link cable is configured? Did you do a compare of the before/after config files to see what exactly changed? Just being curious while scratching my head as to the differences.
It is indeed a great pity that this sort of an issue ONLY affect the top two most expensive Experts in Devialet's lineup. It also affects 210-Pro but I am yet to see multiple users of 210-Pro as probably they end up buying the 220-Pro.
Coming back to your questions, I did not change 'a thing' in my setup except inserting 2 SD cards and allowing my 440-Pro to read the config files.
And yes, earlier, I was using only my Master since I have a single source which is streaming, hence the Ethernet input of the Master as my only input and No Trigger cable.
When I bought my Dual Mono in 2016 as D400 (Master & Companion), I initially started out with the stock RCA (sPDIF) - -> RCA (sPDIF) cable and few months later also tried the RCA (sPDIF) - -> AES/EBU XLR. I found that the RCA->AES to be much superior to my ears. Hence, I had Audioquest build me a RCA->AES cable that I currently still continue to use. In 2018, I had my D400 upgraded to 440-Pro CI and I continued to use them as a Master + Companion till 2 days back.
Upon configuring the SD cards as {Master-L + Master-R}, I listened to my setup and the next day, inserted my older {Master + Companion} cards and listened again. Immediately, the dense center fill lightened up and that vibrant energy very slightly receded backwards towards the Front-Wall. Once again, after 30 minutes, I reverted back to the {Master-L + Master-R} SD cards and immediately the sonics were more dense and bolder.
I am still listening to my "new config" setup and realise that I will stick to this and not the older {Master + Companion} setup.
Incidentally, I recall last year when I got an EMM Labs MA3 (Streamer+DAC+Preamp) with Bricasti M28 monoblock power amps for trial at home, the center fill was just like how it is now, i.e. with {Master-L + Master-R} config and I kept scratching my head as to why with other electronics, the presentation is different yet more realistic. I sincerely thank @daniel.avasilichioaei for showing the path to solve this crazy Devialet dilemma.
Thank you for the write up. I am tempted to try this too. Just to be sure, you didn’t change the way the speaker cables need to attached to the double mono setup either? I fear breaking my speakers if I do things wrong.
The workaround has nothing to do with speaker cables: you don't have to change anything here.
If you are already using dual-mono without a trigger, then the easiest and safest way to apply the workaround is as described in post #26 ([url=https://devialetchat.com/Thread-Stereonet-Devialet-Article?pid=106420][/url]https://devialetchat.com/Thread-Stereonet-Devialet-Article?pid=106420#pid106420):
- The MASTER file is the same.
- For COMPANION file, just edit the MASTER configuration and change audio channel (left / right) and audio input (and name, if you want).
