Is there a media player Android with high quality ?

every android device I bought is just awful

Have you checked out the Nvidia Shield box?

PQ wise that would be EGreat based on HiSilicon SoC. However, their FW support is lacklustre at best plus the SoC is quite old.
Have a look at my Zidoo Z9X review over here:

Its not perfect but basically the best PQ of a media player with support for almost all the latest features and codecs.
