Its a hard to read review, possibly due to translation limits. Looks like the author had a bad config setting, enabled SAM for the speakers which are not SAM certified and wrote about that experience. He thinks a single 220 didn't do it for him but 440 did. I dont think its negative. At the end it says this....
"the title Devialet Expert 440 Pro showed its claws and to put it bluntly "it did it". It is true that the final effect was difficult to classify, despite the obviously aspiring price, to the High-End, but we can safely say that it is a high-class Hi-Fi in a truly designer and lifestyle style."
