I'm still a bit sceptical they'd be able to compete though, what with not having the large power advantage given by bridged mode, plus advantages with electrical isolation. A nice compromise in future, if Devialet could shrink the components somewhat, would be a dual mono in a single box.

I was once invited to Lawrence Dickie's house for a long demo of his beautiful Gyia G2 speaker which we drove with my Devialet 250 and 2xD250 in dual mono. Surprisingly the single D250 came out best (big surprise to me but this time I was reassured by having a pro confirming my impressions): superior soundstage, transparency, bass. We double checked the DEV dual mono setup and it was correct. I had a similar experience in the past with my Wilson Sophia 2: the single 250 was in that case as good as the dual mono. I'd love to hear how big an upgrade the 250 pro is vs the 250 expert: I am staying with a single box!
Well this should be relatively easy for all dual mono owners to test! Just reconfigure and compare! That's the beauty of a forum like this.
Before I committed to the 500 I carefully evaluated all Devialet models at home with my (then) Sophia 3s. The Dual mono was the clear winner and a no brainer for me at the time. This was because I was running a full Linn Klimax system at the time and with the trade in I was pretty much neutral in terms of financial outlay.
I would say one thing however: the dual monos IMHO are very sensitive to the cable that you place between them. In particular many have supposedly experienced big gains with an RCA to AES connection, even Devialet were recommending this at one point for technical reasons (presence of a transformer at the AES input). Then there was talk of the Crystal SPDIF cable (that shipped with dual mono units) not being up to scratch although I never tested this myself. At the time (going back a couple of years) my dealer confessed that in dual mono demos he preferred to use a cheaper Transparent cable instead of the Crystal. My own experience comprised of going from the stock (unbadged) Transparent premium SPDIF to a Ref XL and being absolutely blown away by the gains to the point of not really understanding why and discussing this with Pedro at Absolute Sounds. If I recall correctly his claim was that the slave (oops sorry, companion) was very susceptible to jitter.
I believe in fact there were some issues going back a while ago with the synchronisation of dual mono units which were corrected by a firmware update, I think the release notes mentioned something about correcting jitter in the companion. I do remember at the time there was some discussion around this on the forum with some users being unhappy with the dual mono performance. I should add that I was never affected by this issue, or at least I never noticed this.

I think it is a serious error from Devialet not to provide a separate connector and cable to use between mono units. Some sort of "bus" connection that is immune to jitter/noise with error correction and necessary communication between units for proper operation.
Using SPDIF and even RCA for this is not the best.. If there is a big difference between link cables, then there is a risk that the two channels sound different. For me this is one of the reasons to stick with a stereo model. I know I might get better sound from a pair of amps, but in my setting the companion would be 2-3 meters from the master which means a long link cable. Not ideal at all.

Something like an Ethernet cable...
Unfortunately Guillaume, the O d'A configurator doesn't allow a mono configuration. Not that I'm interested in trying. My C1's seem to like the 1.3kWatt of power

Absolutely! Kii uses ethernet cable for this purpose. The signal is proprietary not ethernet.

By all accounts Ethernet seems to be working pretty well for the Rednet gear too.... Why have a proprietary system called AIR over Ethernet that's unparalleled but not use it to link your own hardware together? Oh....

I think that NickB has his amps widely split. Wonder what cable he uses between his amps....? Nick?
So, is everyone agreed that changing the connector cable only affects the sound of the Companion? Does anyone use the Cabledyne RCA to XLR to connect their amps? I need to rearrange my rack which will mean a 2m connecting cable and I'm wondering which way to jump. How much is the supplied Crystal cable worth? I can't see anything similar on the their website.
There have been a lot of discusions regarding the link cable how it works and what it transmitts to the Companion from the Master. I use the Cabledyne RCA-XLR cable between my Devialets.
Hi,
Has Oxfordaudio an assessment on the "250 pro" coming from a "split 1000"
?

Hi
Yes my D800 are about 3 metres apart on the wall behind my speakers. All my cables run under the floor so the connecting cable is about 4 metres long. As I am very happy to make my own cables I made a Klotz 5000 cable which works fine, then a friend found/bought some ex BBC 75 ohm coax cable and I have made up a cable with that, seems to sound pretty good to me.
Had a Mike Oldfield session yesterday - I know its not fashionable to like him but there is some complex stuff going on in there. After a couple of albums SWMBO asked why it sounded so detailed and that the percussion was unusually clean and clear so I suppose something is working quite well.
Also meant to post here that coming from a D400 to the D800 that it is a quantum leap in performance and seems to drive the Magico's fantastically well, can't wait for the 1000 PRO now should be even better.
Mind you all this should be taken with a pinch of salt as I am still listening with my faithful Raspberry Pi and HiFi Berry Digi+ as a Roon endpoint and loving it so my hearing is definitely suspect!!!
