This is what I believe, or at least think, what most likely happened. My Devialet was being fed directly by the roon music server and I enabled this Within the software. Then I connected the music server to a dCS Network Bridge which was connected to the Devialet through a digital XLR. It was a mistake to enable both of them. During switching, there was a lag time phase in which both inputs fed the speaker. That means double the power and twice the current. I heard a clicking noise from both speakers and the left one died on me (The tweeter in the mid range driver but unfortunately the whole unit has to be replaced). What some experts have told me that maybe the right one sustained some damage as well but did not malfunction immediately. Over time, and I listen at moderately high volumes, It eventually malfunctioned as well. It is their opinion that after having replaced both units the speakers would be fine. Hopefully that is the case but this problem has ended up costing me $4200 in total. Just about everybody has told me that this is an astronomical tag for a mid range/Tweeter driver. I have to admit that I was less than enamored by the response by Vienna Acoustics. I then sent an email to Eton in Germany that make the driver to see if I can get it at a lower price but have not heard from them yet. One thing is for sure: I am now going to save up for a new speaker; in the event the speakers fail again I’m going to get a new pair. It is a great bargain at $27,000 and one of the finest because on the market: kudos audio triton 808. Buying A high-end speaker is like buying a luxury automobile. You just don’t pay for the car, you also pay for the support and service later. After speaking to the owner at Kudos audio I was satisfied that they have a much better approach than Vienna Acoustics
