I’d be inclined to report the issue to Devialet customer care, regardless.

If you have a doubt, why torture yourself.

Any update shouldn’t make it worse.

Not certain quite what you mean by "echo filling" - echo feeling? I don't hear an echo but I do hear what I would call a bit of "hollowness" to the sound. It's hard to say whether the miv you used for the recording (phone?) is contributing to that. I don't think there's a problem with your Golds but I do think you could have some problems with what you have them sitting on and in the room itself which could be contributing to what you're hearing.

There are a few things I can see in the video that could contribute to sound problems.

First, you've got your Golds sitting on small coffee tables which protrude around the speakers on all sides. That means that you're going to be getting reflections from the front part of the coffee tables which protrude in front of the  speakers. Moving the speakers forward on the table so there's less, or preferably no table area protruding in front of the speaker may help. Getting proper stands for the Golds would probably be a good idea in the longer term.

Second, there's the coffee tables in front of the sofa, one of which looks like it sits partially under the other. That could create a bit of an "echo chamber" between the top surface of the right hand table and the bottom surface of the left table. Removing one table and putting a cloth covering or blanket over the top surface of the remaining table may help.

Third, you've got the screen, which is itself a reflective surface, in a recess in the wall between the speakers with flat surfaces and a lot of probably reflective objects below the screen plus a soundbar. I assume you're not using the soundbar with the Golds. If you are, and you don't have a way of matching the arrival times from the soundbar and the Golds then that may be the cause of the problem. I would not use the soundbar in conjunction with the Golds. You can't do anything about the recess or about the screen given that you want to see the screen (some people cover screens with blankets when listening to music so that reflections from the screen don't cause a problem) but removing the objects in order to eliminate some of the reflecting surfaces may help. The recess under the shelf everything in the recess sits on may also be an issue.

Dealing with all of those potential issues is going to change your room a fair bit and I would not recommend doing anything permanent unless you were sure that it was going to help so here's a list of experiments you can try very easily to see if they make a difference, and what you can do on a more permanent basis if you find one or more of them helps. Try each of these things one at a time so you can see which work and which don't, and you may find that more than one helps in which case you can choose to do something about all of the things which work or only about some:

1- sit the Golds on something that doesn't protrude in front of the speaker's bases. You can try moving them forward on the tables you're currently using as a quick experiment but proper stands would be a good idea in the long term as they may be transmitting vibration to the table surfaces which may be resonating audibly. If you can't move the speakers forward on their tables then try putting a blanket over the table surfaces below them in order to reduce reflections.

2- If the soundbar is on then turn it off and just listen to the Golds in stereo. If that helps then consider removing the soundbar and just running with the Golds or, at the very least, using either the soundbar on its own or the Golds on their own depending on whether you're listening to music or watching video.


3- remove all of the small objects and bottles within the recess. If that helps, either don't put them back or only put back some of them. You can experiment to find out which ones make the most difference.


4- try sticking a few pillows in the space below the shelf in order to reduce/eliminate reflections within that space. If that works then try sticking a few carpet tiles on the underside of the shelf where they won't be seen. Sticking carpet tiles on the underside of tables is a trick used by some restaurants with hard reflective floors to reduce reverberation in the room so it may help in your situation. Alternatively you could even consider getting some acoustic foam bass traps and putting them there.

5- remove the lower height coffee table in front of the sofa. If that works then just keep a single table there.

6- cover the tables in front of the sofa with a blanket to see if that helps by reducing reflections from the table surface. If it does, then use something as a table cloth over the table.

7- use a blanket as a rug under the table/tables in front of the sofa to reduce reflections between the hard floor and the underside of the tables. If that works then get a rug to use over the floor there.

I can't guarantee that any of the above things will make a difference but it's easy to try them all one by one in order to find out. The odds are that it's something to do with your room acoustics that is causing what's bothering you and the things I've suggested are all things that address what could be either causing or contributing to your problem

There may be issues elsewhere in the room contributing to your problem as well but I can't tell without seeing images of the rest of the room. If some of the above suggestions help then I'd look further around your room and pay attention to hard reflective surfaces such as glass or steel and see about covering them. Pulling curtains or blinds over windows while you're listening may help. If a rug under the table/tables in front of the sofa helps and there's a large area of bare floor behind the sofa so not visible in the video, then a rug there may help. If you've got a kitchen area behind you then you could have reflective surfaces there such as refrigerators and wall mounted ovens and  the like which you won't be able to do anything about but anything you can do to reduce reverberant reflections in the room may well help.
