New beta firmware 7.1.3 released

[ogs]

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... 

I do not own two Devialets, otherwise I might try this
Apart from that, what's flawed in dbt is the fast switching. I hear differences when I play music, not when I switch back and forth. Fast switching is very good at hiding differences. That is probably why you did not hear the difference between 160kbps mp3 and flac, unless the flac was made from the mp3 that is..

Hehe, I know that there are a lot of fake flac music files around, but trust me and try it yourself. Take one or several lossless files that you really know well and that are truly lossless. Then take a modern mp3-encoder like lame and convert the source files yourself into different bitrates (do not download them from the internet, because they might be bad rips, old encoders or multiple compress files). then compare them with the double-blind test of the ABX-Plugin of Foobar. It is really hard even to distinguish between flac and 128kbs mp3. Please do it, it is really interesting

But of course I listen to flac myself and I will not change that, because mp3 is at best only percieved as good as the original. Why not listen to the original itself? But my old assumption that there would be a big difference was clearly biased by the bad material that you can find on the internet.

Now we are getting a little bit offtopic, but for me the upgrade process just takes to long to really compare the two firmwares.

Yes this is getting off topic, sorry about that!
I've done my share of ABX. I've some times heard differences in quick switching, but it does not tell me anything about quality. My opinion is that  DBT is flawed. I do not do that any more.
