Upgrade popcorn hour A410

[Masterkale]

Hello i am new to this forum and i want to improve my sound from my mediacenter.

 

I am owner of a popcorn A-410. This mediastreamer got just a power adapter of 4A as power supply.

 

If i add a linear power supply instead of the power adapter, will this improve the sound quality?

 

I tested a few thing and noticed;

 

The sound of my normal (gaming) PC is with HDMI out exactly the same as mine popcon hour.

 

Playing from a usb stick directly into my av8801 receiver improves the sound.

 

Because i love to watch movies i would like to build an audiophile media streamer.
