Hi there guys! I need your help.. I don't know a better place to ask for help then on an audio/stereophiles forum. I've uploaded video to YT describing my problem (it was easier like that I guess).

My knowledge about this issue is really limited unfortunately.. :(

I'll be patiently waiting for replay.

Thanks in advance,
Morphy.
