moODe 6.1.0 upgrade

[Miss Sissy Princess]

Upgrade from 6.0.0 to 6.1.0 not restoring sound quality for the for the HIFIBerry Dac+ Pro device that is exist with moodeaudio on 5.x version. :/

Have you shown with double-blind tests that you can discern which version you are listening to?

I ask because it's all too easy to convince yourself that there is a difference when none exists.  In fact, studies have shown that someone can play the identical track, on identical equipment, twice, and the odds are good people will believe that they hear significant differences if they are told something is different.  I've done this by telling someone I was playing a FLAC file and then an MP3 file of the same track.  Despite my having played the same MP3 file for both, multiple golden-earred audiophiles told me that the FLAC version sounded much better.  One even went so far as to tell me that I needed to get my hearing checked if I couldn't hear the difference.  

You think you can trust your ears?  Then watch this video and tell me how you did:  https://www.youtube.com/watch?v=G-lN8vWm3m0

Thanks. I was see and hear this document, but i think that problem that i was writing - not coreesponding with this material

I referred you to that video because it very much relates to what you are saying -- it demonstrates how you can be completely sure you are hearing something and be completely wrong.  

And, as I explained in the text, studies have shown that people tend to hear differences when they expect to (expectation bias), even when no difference exists.  Read this:

If you can't trust your eyes to tell you that these two black lines are the same length, how can you trust your ears to tell you whether moOde 6.x sounds the same as moOde 5.x without doing a blind test?
