Hi all

I would just like to share my recent experience with you guys.
I'm a d200 owner and decided to go for a companion rather than the pro update.
All was good and I was very happy until the companion made me notice some issues with my Master (which was bought brand new)

The message I sent to support below

I recently bought a companion d200 to upgrade to a d400. 

This was the first time I have seen 2 units side by side in my house and I noticed that the finish of my original d200 has circular marks that can be seen in bright lighting. 
I asked my dealer about this and was told that this was a b grade finish. 
It's as if it has been buffed with the wrong grade and is very inconsistent. 
The companion unit has no marks whatsoever regardless of the lighting. 
I also noticed a whirring sound from my master unit which isn't present in the companion. 
The companion is second hand with none of these problems, but my master was bought brand new with a rough finish on it and a noise coming from the unit. 
I believe its from a ferrite element in the PSU but it is audible from my listening chair. 
What is the point of having excellent signal to noise ratio but the unit itself is making a loud noise that distracts me from the music. 
Also my listening chair is several metres away and I can hear it when nothing is playing or during quiet parts of the music. 
Please can you sort these issues out. 
For £5500 I expect none of these issues.

Below are images and video I attached to clearly show the issues

Thank you for your patience. 

We reviewed the case with our team, especially the one managing the production quality. 
Based one the video, we could not detect something abnormal, that would be solved by any kind of exchange or repair. 

This drove me mad.
How can anyone say that they cannot see a difference from this video?
I also took more pictures making it as clear as possible exactly where the damage is.

My message below
I've added pictures of the case and highlighted the exact places where you can clearly see machine marks. 
You have to admit that this is a very sloppy job, and a terrible finish. 
If it is hand finished it is very uneven with lines going all over the place. 
None of these issues are on my companion. 
In a darker room it isn't that visible, but in my new music room I plan on having the units side by side and the down lighting will make the 2 cases look completely different.

So my master has been with devialet for 2 weeks and they have concluded the following

Our team studied the device on two points:

- the casing state
- the ferrite noise

Neither of these presented any issue here. 
The casing is in our standards for the associated year of production, and we did not hear any ferrite noise. 
We still wanted the opinion of our original expert engineer to see if he, perhaps, hears a noise. 

Considering he is very busy at the moment, this will take some time to get a reply. 

I'd just like the opinion of you guys, am I being picky here?
The 2 cases look different and I can hear a loud whirring sound from my listening chair.
What would you guys do in this situation?
I also ask that people with 2 units check the finish of both to see if they match or if they have a similar issue to mine.

Thanks for reading
maybe the noise comes from your power line, maybe you can solve this problem with a filter. I could also hear a noise from both my 800 units which has completely disappeared after upgrading to a 1000pro. But this noise was only hearable from about 1m distance or so...

It's definitely from my master as i don't get the noise from my companion.
Either way, which filter would you recommend?
Thanks

There's been a lot of discussion on the forum about the power supply noise in the original Expert series (for example: here, here and here).  It seems to be a matter of luck whether or not a given unit makes the noise or not, and how loud it is.  A lot of people end up just living with it (as I did).  As far as I know, Devialet consider this completely normal (see this article on their support site) and you might have a struggle to get them to replace your unit just for that reason.  Maybe your dealer might be able to help if you've bought your master recently.
There were some issues with the PEM filters on the Expert range which usually resulted in a bit of a burning smell, but it's not inconceivable it could hum too. In fact it could potentially hum in normal operation too if there was noise in the mains, e.g. a DC component, but then the companion would surely do the same?  I'm sure a few people on the forum have had similar humming problems so hopefully someone can chime in (sorry, I missed thumb5's better response than mine above!).
I'm wondering if the master has the old PEM (Schurter filter) and the companion has a new or replacement one? Devialet are aware of problems like this anyway so to get such a curt response is disappointing, though not completely unexpected.

As for the case, I'm not aware of case finish being worse on older units. Mine is an early D170/D200 and it's perfect.

Interesting
I remember reading about someone else who had an issue with the PEM/ferrite hum/whirring and was able to get it replaced.
The problem for me is I didn't know that all units were different until I had my companion which was silent.
It's a big ask for me to live with it considering devialet can solve the problem and they have my unit at the moment and are saying there is no problem.
It's one thing if all units make a sound and they just said that to me, but they say they can't even hear anything.
I can hear it across the room!
Were you able to hear the recording of the sound I posted?
It seems like they are eager to take my money and claim to give a 5 year guarantee but if something actually goes wrong/isn't right, they aren't too eager to sort the issue out.

As for the finish of the cases, that has further enraged me knowing that your 170 has a perfect finish and goes against their reply of:
The casing is in our standards for the associated year of production
Does that mean their quality control over the years is getting worse as sales increase?

Can anyone else comment on the finish of their units?
My dealer also told me that it was a B grade finish.

I'm a little disgusted that I have to put so much time and energy into communicating with devialet about the same thing over and over, only for them to say there are no issues even though I have provided photographic/visual and aural evidence.

The first Devialet D200 I bought had the same issue of the circular marks. At first I thought the unit was scratched and that these were fine scratches. So I did call up the retailer to raise the issue and he re-assured me the unit was brand new. As it is a well respected retailer I left the issue at that. To be honest the polishing is finished off poorly and those circular mark should not be there. As for the power supply issue I cant comment as I never had the same issue.

You are definitely within your rights to complain about the poor customer service. Devialet should just change the case and replace the PSU. If you are not happy with Devialet just sell up and move to another company.

Thanks for commenting.
Did you manage to get your d200 replaced in the end?
I do a little knife making on the side so I know about working with metal and they have done a really sloppy job.
I've hand polished knives to give them a mirror finish and the finish on my unit is just terrible.
Really inconsistent with lines going everywhere.
I'm glad I'm not coming across as someone complaining about minute details.
I just don't understand why they are making such a big deal out of all of this.

I did not get the unit replaced. I just thought that all unit must have been finished similarly, so did not really bother with it. But I was not particular impressed. The finish on these units suffer from myriad of problems like this one:

Devialet makes fantastic sounding products. So I give them a pass on this, and just focus on the music. I have two D200's and both have swirl polishing marks on them. So I think it is more common to find that kind of finish on these units. You might not get far with a change of case, but they should change the PSU. I would not be surprised if your unit does not make any noise when you finally get it back.

I think it is terrible that this "luxury" brand won't take care of this issue.
Although its not ideal, at least your 2 units match and have the same finish. (even if its the rough one}
Mine will be side by side and the downlighting in the room will make them look completely different.
I didn't think too much about the finish at the time as i thought all units were like that, but after getting my companion I'm really unhappy.
Also my dealer even said it was a b grade finish.
The companion is perfect.
It drives me mad.
The psu in the companion is only audible with my head right next to it.
I hear nothing from my listening chair.
The master on the other hand definitely needs something changed.
It's distracting and can be heard at low volume.
Even if they can't make it as quiet as my companion, they should be able to make some kind of improvement.
Instead they just say that they can't hear anything.
Absolutely ridiculous.

Anyone else notice the circular marks on their units?
