One year after 13.2.0

[David A]

@David A, editing the configuration file to restore a previous known-correct version is rather different to editing it to change a setting.  The file contains a CRC and will not be considered valid if the contents don't CRC to the correct value; in that case the amp will reject the file and fall back to the default configuration.

The first step in any "do-it-yourself" approach would be to determine the exact type of CRC (polynomial, reflection, etc.) Devialet use and what contents of the file it covers (e.g. whether or not it includes white space, line endings, etc.).  There are very many possible combinations.  Believe me, I have tried, but not yet found one that works.

I suspected there might be some "gotchas" involved which is why I said in my last paragraph that Devialet would at the least provide a very complete guide to the creation and editing of config files. A stand alone app we could use on our own computers would very much be the preferable option and, if they were going to do that, I think it should be possible to include their whole library of SAM profiles since config files are actually quite small even when they do include a SAM profile. The full library of profiles is probably not all that big a data set.
