With Companion or Without Companion?

[sam1000]

It was my understanding that a "companion" unit is a slimmed down version of the full product meaning that it is missing some hardware, like networking capabilities, etc. It is also my understanding that Devialet no longer sells companion units and if someone wanted to make a single unit a dual-mono unit they would have to purchase another full product (matching unit).

According to Devialet's website, the Expert 210 Pro Dual "combines two Expert 140 Pro units", likewise for the 440 and 1000 each "combines two Expert 220 Pro units" and "combines two Expert 250 Pro units" respectfully.  Does this mean that the second unit in the 210, 440, 1000 kits is a full product or a traditionally slimmed down "companion" product mentioned above?

I have tested this with a recent purchase of 440 from another member. I paired the remote with each unit and played music via streaming. So, only thing missing is a remote control.
