New beta firmware 7.1.3 released

Hehe, I can't resist to give my comments on the new firmware as well.

I did extensive listening with 7.1.1 right before the upgrade and right after. Then I thought it is clearly identical, maybe just adding some beta-functionality to be controlled by dialog. Now, after a week, I also tend to believe that the sound has gotten better. For example clearer sound while listening with high volume. I can confirm the temperature drop of about 4° while seeing the status with tone controls. However, if I touch it by hand, I do not notice any difference.

Concerning sound quality, I am fully aware, that it is probably just our minds playing tricks on us. Like the expectation bias or the group bias etc...

Lets face it, we are always on the look for something we can improve, otherwise we wouldn't be in this forum, and therefore we are somewhat biased. Even tough I only listen to FLAC, it was an eye-opener for me doing a real double-blind ABX- MP3 vs FLAC-comparison with Foobar (https://www.youtube.com/watch?v=jt7GyFW4hOI) (http://www.mpex.net/info/abx.html). I was convinced before that FLAC was clearly better than Mp3, but I failed the test even with 160kb Mp3's converted for the first time.

Maybe someone with two Devialets would be able to do a double-blind test, with fast switching between the two units. That would give a clearer picture.
But lets have some fun tuning our equipment none the less... 

Interesting read. Thanks for sharing.

I specially like this Post-Purchase Rationalization

Last Saturday, I was listening to a 128kb/s MP3 of a live recording of JJ Cale singing After Midnight. It was by far the best recording I heard in that 1 hour long session. It had space, bass weight, beautiful voice, depth , width etc. There was absolutely nothing wrong with the whole picture. I'm sure the higher resolution stuff has the potential to sound better but this recording is proof that potential and practice are two very different things. I'm definitely not discarding low resolution just on the numbers. 

Thanks for the recommendation on JJ Cale. I tried listening to a FLAC recording of the same album with a stream version (which most likely in 128kbps or max 320kbps MP3). There is definitely a great improvement with FLAC version. And, you are right, listening to the stream version with Devialet is still enjoyable.
