Stereonet Devialet Article

The fact that there is any sonic change is remarkable and makes one wonder why Devialet has not suggested doing this or even acknowledged that it as a viable option.  I will definitely give it a try sometime soon. 

@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.
