Updated the original post once more with HibyMusic experiences.
HibyMusic in fact is a real alternative to USB Audio Player Pro with even wider native audio format support (DST DSD and DTS-CD included). The big real drawback is controlling the HibyMusic UI which will only work via touch/mouse field actions. Any standard IR/BT remote is absolutely useless with this APP.
There is an option though to run HibyMusic just in Server mode on the Zidoo and HibyMusic in Client mode on a smartphone. That way the Storage and the Audio Playback (via USB DAC + AMP) of the media player is used controlling the UI integrally via the smartphone. Would have been a great setup if it were using IP but in fact it uses cumbersome BT for its communication.
For the time being swapped USB Audio Player Pro for HibyMusic (in Client/Server mode) as my favourite player APP.
I changed himedia for zidoo x20 pro and today I installed Hiby Music, the difference in the quality of music is huge
Thank You NiceMonkey, I still discover zidoo, I hope I will be more happy with it than with Q10.
I am still wondering if from my configuration (Onkyo TX NR-696 + Teufel Ultima 5.1.2 + Zidoo X20 Pro) I can improve the sound quality by adding, for example, a DAC .But will this not be an exaggeration?
