Upgrade worthwhile itself !!!

I am the owner of Essence One Muses Edition, and was far too curious to see whether the update actually brings what.
I can only say so much, that now reaches the sound through the two supplied Muses-02 ICs a much larger spectrum. The stage is thus definitely larger - and listen to the addiction higher.
The sound is more balanced throughout.
Since both my headphones in the range 5-45000 Hz work (Sennheiser IE800 and Denon AH-D 7000), I have much more fun at both headphones after installing the update. With the Muses-01 to me was the sound beforehand to height stressed. This changed significantly with the Muses-02.
