The problem is also present on any analog input as everything is digitized to at least 96kHz by Devialet. And I believe AIR down samples to 48 kHz so that is why it works. Tired USB, SPDIF, Optical inputs - all the same.

The reason I am using RCA to XLR is to connect a 2nd Companion for a Center channel. But the issues are present even in simple configs with just a Master and one Companion.

Very frustrating intro to Devialet.

baddog, how long is your DH Labs cable I am using 10ft/3m cable. Wondering if length can be a problem. Tried reseting und upgrading firmware, doesn't work. Thanks.

My DH Labs cable is .7 meters in length (2.29 feet)

p.s. and just like Ian I am using the phono input with no issues.

That's an interesting point: the length of the cable might be important especially if it's not a good impedance match (although I saw you tried several - were they all that long?).

I tried AIR and it said 48kHz, so it worked.

I also asked Devialet. First it took them a week to conclude it cannot be impedance problem and it is likely that the cable is physically broken. So I got a bunch of other cables and tested everything to the same effect (all cables were 3m long). So they changed their mind and now say "we are facing an impedance problem : source is 75R, receiver is 110R, unless using a conversion transformer, impedances won't match and will prevent from proper operation at higher frequencies." I think its fair to say that Devialet doesn't expect RCA to XLR to work even though they advertise it as a viable option.

I used a RCA to XLR cable to connect my second D-Premier to my original one to produce a dual mono more or less as soon as the capability was added to the Configurator with v3 or v4 of the firmware. I continued to use it when I updated them to a pair of 250s and connected them as a 800, so for the best part of 4 years.
Never a problem, and back then many believed this connection gave the best SQ for a pair of amps, including me. I use the supplied link cable now with my O d'A and use some inputs on the companion.

Thank you for all your advice. If only Devialet's support was as responsive as this community.

I found a solution. Sweetwater 110Ohm cable works. It looks like at 3m cable length the setup is very sensitive to cable impedance.
