+1 Me too.
A tidy and correct translated homepage would be a good beginning also.
Additional a continuously supported held desk - not even visited with appeasing comments from time to time.
In times of trouble more important than anything else.
Last but not least an exact changelog of every update.
And of course short dated information if anything goes wrong with a new Update.
Until now they do have nothing of all that.

6.0.8 works fine - changes to just a couple of files compared with 6.0.7 - to the fw-list file (which seems to be a text and/or control file) and the psu-0401 file (power supply I guess).
In fact the fw-list file seems to partition the updates in some way - those for versions 01040101 and for versions 01050000. Only the latter has been updated with the psu-0401 which, I guess is for the 110/170/240/500, whereas I suspect the psu-0302 relates to the D-Premier and the dual-mono. I seem to remember that Devialet said that there was different power supply management in the new units compared to the old.
Anyway, sound remains fantastic and Air dropout free so far.
The new configurator now seems fully functional apart from the restricted save facility and the non-operating amend facility in My Maison Online.
The new configurator has more flexibility than the old provided you explore it and figure out how to supress inputs and rename inputs. A great bit of work from them.

there is one bug and one missing functionality, at least I cannot find it. The automatic dim option for the display is not available anymore, and if you set the display brightness to a lower value it still shows the full brightness. Only in standby it goes to the lower brightness. Have reported that to Devialet already...
Unfortunately, I have now been having the complete drop of the system problem. Twice already today after updating to 6.0.8. I have only listened for about 3.5 hours today. Strange thing is, the D-Premier still says its connected on the info screen. Anyone else having the same problem?
Yes, I also suffer from Sudden Devialet Death Syndrome, which occurs unpredictably after anywhere from two to six hours of trouble-free play, even though I have an unwavering signal strength of 31dBm. Annoying, but not maddening like the now fixed dropout problem. Closing down Air2.1 and restarting the D-Premier reactivates play. I guess the poor thing grows weary of its existence and needs a rebirth. To quote the Devialet site: "Audio Renaissance, the Devialet era!" Humbug.
Lol, well put.
Also have noticed it is pretty much non responsive to any iapp, phone or pad.
Do the info on the devialet screen (amplifier)says it should be ok ?
Been working fine here for the last days (16/44),i did the hole routine over again with the software download and air,no connection problems soever last days
wi fi signal 51 dBm /using imac/itunes/bit perfect disabled/eq disabled/Target buffer 3000/16bits/44
Had only some problems with transfer the config file to the SD card,but solved now

Yesterday I had a nice and long listening evening. Without any connection loss. I But what I could experience after some hours was a slight cracking here and then. Similar to older vinyl records.
....
Also I have audiophile friends that swear on WAV files in favour to FLAC or Apple Lossless files. Actually, I wasn't able to hear any difference with my HTPC configuration. For me that means, there HAS TO BE an influence by what ever... but not in terms of my configuration.
I have to repeat my central opinion: If somebody examines a difference you are not able to reproduce, this does not mean there is no difference!
No more drop-outs for me up until now, however I could not listen for longer than an 1-2 hours at a time...
My Router ( configured as repeater) is sitting right next to the Devialet, however the Mac needs a LAN cable to the router to allow reliable High-res streaming (confirming what was stated earlier).
@ marting, fully agree with what you said - I wouldn't question anybody's listening experience. Yet I also suspect not every "bit perfect" solution really works "bit perfect". Therefore statements from Devialet (or anybody else who knows) as to how well this machine works and behaves with different players on a technical level would be helpful...
Hi oelli, responding to an earlier post of yours: Thanks for the great explanation as to how Air2.1 works in the different OS environments.
I noticed that with Air2.1 set to "iTunes bit perfect", you can watch in the Mac Audio settings window how the sampling frequency of the D-Premier channel is automatically changed according to what is played in iTunes.
Interestingly, the bit-depth shown in thenAudio setting remains at "2 ch. 16 bit integer" (unless changed manually) even when playing a 24 bit file. Any idea what to make out of this?
It is not going to be commercially wise for Devialet to say "works best with "x" computer and "y" software, second best with "p" computer and "q" software" as this will soon be interpreted on this and other fora as "does not work optimally with ...".
A suggestion: Just take a look at what Devialet choose to use at shows, or in their own shop, or when doing dealer demonstrations; and if you want an architecture where sound quality and connectivity integrity are considered optimal, follow Devialet's lead.
If you open Audio MIDI setup in the Mac utilities folder, you will get a more accurate reading of what is being output to Devialet Air.
Interestingly, if you adjust volume while using Air2.1, you will see that the sliders in Audio MIDI move back and forth. I had always understood that ideally one wants those sliders always at maximum to achieve bit perfect output, leaving the volume control function to the receiving DAC.
If you play iTunes via wired connection into the Devialet, the sliders remain at maximum output, as is the case with the wired Audirvana external player. Audirvana's developer emphasizes that the Audio Midi output must be at maximum to achieve bit perfect play.
I am reporting all this more as a question than a knowledgeable assertion. I have no technical expertise beyond what I read and would appreciate being corrected or confirmed by someone in the know.
The essential question is: Does Air2 move bit perfect streams to the Devialet?

Hello, I also have found this oddity that the bit width is not modified in Audio MIDI Settings.
Internally Mac OS X handles all audio data as 32 bit and so the sound driver (AIR 2) gets always 32 bit float (which can be convertet lossles from 16 or 24 bit integer and back) regardless of this setting in Audio MIDI.
So possibly the devialet sound driver (AIR 2) does not use this setting.
But this is all speculation.
Yes I see that a lot of things get mixed up here because of limited or wrong technical background:
This sliders in Audio MIDI Settings are linked to the volume control and balance of the Sound interface (digital or analog out of mac or sound interface connected to mac).
If you go out from the mac with a wired digital interface to the devialet you do not want the interface to reduce the volume which results in reduction of bits. Therfore this is true for this kind of connection. You want to get all data into the devialet and the devialet make the volume control.
But if you are using AIR 2 which acts as sound card driver, then the Devialet is the sound interface and then this sliders will be linked with the volume control of the devialet and so everything is fine when they change.
But you should not change the volume slider in iTunes, keep this always at maximum because this affects how loud the sound of iTunes is mixed to the general sound in your mac.
Thanks, oelli, for your helpful reply.
I take it, then, that you confirm that Devialet Air does not compromise bit perfect play?

Standy Mode Sleep Mode and Configurator
My D Premier is not always going in sleep mode after running on Air... This is only happening in Air Mode and not with the other outputs. I am still using the configuration from the old firmware. Could it be the reason ?
I tried to upload the old config file in the new configurator but everything needs to be redone manually...
Thanks for your help

Is your Devialet symbol on your computer grey - does it turn grey after you stop your iTunes or whatever? If you have other live inputs, even silent, it will remain black and so your D-Premier will not sleep.
Your old configurator should not be the reason.
Thanks IanG-UK, that has been also a question for me. Actually I am currently fighting with the new 6.x configurator. And as philoouu already stated, the old 5.7 configruation file unfortunately cannot be imported. Now my question is, what does Balance & Tone Control in the General Settings mean?
I do not want to use such things like bass and treble regulation... or is this something different? I do not understand this control, as this is new to configure. Am I wrong?
Thanks in advance for any explanation and help.
Hi Marting and Philoouu
Thanks. If your Devialet symbol does go grey but the Devialet unit does not sleep post Air, but does sleep post other inputs, then I do not have an answer. The Devialet unit must think the Air connection is still live. You could try a new configurator but I doubt that will solve it. Both old and new configurators are set to default sleep after 30 minutes (I think) which you can vary or override all together. (See General Settings, General, Power Saving.) Just try the standard solution of turning everything off (computer, router, Devialet) and unplugging and then reconnecting - this might reset something.
The new configurator does work, but not perfectly. I use dual mono which means the new configurator is further compromised because you cannot save two configurations on to "My Maison Online". Whether single or dual, saving or importing, the My Maison Online is not effective.
You therefore have to save the configuration files on to your computer then export them to a clean SD card. Be sure to set up new subfolders because all the config files have to be named dp_cfg.txt - be sure that when you save them that that is the name of the file. I had some files emerge as dp_cfg.txt.html (don't know why) and obviously these would not work.
On constructing the configurator, I suggest you go straight to the Advanced Configurator screen - I think this is easier to use than the "simple" mode. In General Settings, just ignore the balance and tone controls since they default as entirely bypassed if you do not adjust them. You can also exclude them from normal selection from the remote, again by using the General Settings.
If you do select them and use them, they adjust bass around a 100hz pivot frequency and treble around a 2000hz pivot frequency. Both these pivot points are adjustable. If you select them and don't use them they are effectively bypassed. I don't know the shape of the bass/treble adjustment - they might be conventional or might be like the Quad "tilt" controls - Devialet do not say.
I hope that helps. The new configurator is not wholly intuitive but I can assure you it works, and is more flexible than the old one. You can supress inputs, rename inputs and configure the remote in more ways than before. I just have Air, XLR, Line1 and Optical1 selected, using names of my choice; and I set the two remote buttons (other than source) as mute and treble/bass/balance. Good luck.
