That's obviously very sensible advice but one challenge is that it's not always possible to predict in advance what specific configs might be required e.g cartridge changes, speaker changes etc

Obviously Devialet's online configurator won't let you do that but at least you can go back to a config that you liked until you are forced forward with a hardware change or major config change.

It would also be much better if Devialet didn't block manual config file edits.

Being as they are pretty basic text files and reasonably clearly laid out,  most people could survive (with community help perhaps) for many years simply through editing the files.  That way, the unit would be functional for years to come whatever happened.  As it is, I sense this firmware/configuration thing could be a real stumbling block in the future.

Yes, the check makes sense in some ways, but in general the only types of users that tamper with such things are advanced users - who would really benefit from being able to edit the files themselves, or even see the arrival of third party desktop editors.  Would probably mean more intuitive software with less bugs too.

If people start messing up with these parameters, and that causes a damage in the amplifier, who would be responsible ?

I have a D-Premier and i am very happy with the new update. I used 7.1.1 for a long time and went directly to 8.0 but it was horrible so i had to go back to 7.1.3 which was quite ok.

I agree, in fact I could have written exactly the same comments as you about the various versions of the FW

The only downside of the latest SQ improvements to the firmware seems to be that the amps are now even more revealing of the quality of the source  and recording quality. So I will finally have to sort out my source and perhaps try some 'tweaks'.

I think its not a disadvantage, i noticed SQ improvements on all songs i listen to, even with mp3 256

Yeah - its not in any way a disadvantage, it just means that I have to be less lazy and finally sort my system out properly.  The thing is that Devialet sounds so good with no tweaks that its possible to avoid much of the work that many other systems require to make them sound good e.g. Naim...

The crossover filter settings are not applied when pre-out is on. This means a full range signal is always outputted to the main speakers whether pre-out is on or off. I though the bass sounded a bit fat so I tested with a 20Hz test tone (I do this every firmware upgrade) and the woofers on my mains were moving too much, clear indicator of the issue.

Since there is no workaround I know of I have to go back to 8.0, report this to Devialet and will probably have to wait for 8.1.1...

edit: will try creating a config from scratch first.
edit2: creating a new config from scratch did not help. Reverted back to 8.0: issue confirmed, it works OK again. Reporting this to Devialet now.

Good news for me and of course those others using subwoofers connected to the pre-out output of their Devialets and/or use the crossover settings inside the Devialet.

They got back to me today and Devialet has solved the issue described above by issuing a new firmware package. It has the same version but the IHM file inside is newer and has a date-/timestamp of 12-6-2015 14:13. Anyone can download it from their website using the regular download link.

I've tested it and it works like it should again!

Thank you again Devialet for quickly resolving the issue. I am a happy camper again!!

Thanks for this Antoine, not that it affects me personally as I do not use a sub, or cross over filter settings.

Whilst I can applaud Devialet for fixing this issue in short time, I can not applaud the way in which they are issuing it! They should issue a new Version number and publicise it in the same way as they did the release of 8.1. It should not be left to you to broadcast the changes - maybe they will issue a round robin note, but I doubt it!

I believe that this is not the first time that Devialet have shown a laxness in their firmware issues (I seem to recall a similar issue with 7.1.1, which had a number of different dates applied to it).
