I came across the following D120/D200 review and in this review, the author mentions the following which affects dual mono setups:
3. One Devialet seriously influences the sound of the other, when switched on and connected to the same power outlet. This one really shocked us. After we started listening to the 120 with the 200 also connected to the power in order for both to remain warmed up, I noticed during the first few tracks how the sound was too closed in between the speakers, and lacking dynamic expression. This wasn't how I remembered my sound. My first suspicion was that the 200 had to have something to do with this as this was the only change in the system. Immediately after I removed it, the sound became clearer, faster, more dynamic and more involving. Soundstage also grew in size considerably. Now, after I moved the 200 to the other side of the room and connected it to an outlet that is on a different mains group, its influence could no longer be heard. Now, it is definitely possible that the effect heard in point 2 exacerbated the effect of point 3, but we did this test twice, using both amps and reversed, and both times the sound improved immediately after removing the spare amp. What's more, the second time we tested this was after having listened to the 200 for more than an hour (well after the volume level was settled), then moving the 120 from the outlet at the other side of the room to the same extension block as the 120, and once again the sound collapsed right away. This is something to keep in mind for people deciding between the two models, as well as for people who connect two units for bridged operation.
Bullet #3 on page 2 under the "Three Observations" section of the review.
