I want to say i increased distance of my speaker from wall and bass is better now

Thanks for your power strip advices @lowrider57 
I should buy it
@lowrider57 
Its my speaker test with slow music
https://youtu.be/ESO7NiVMP1M think its very good and im quite happy

But it cant handle fast and sophisticated genre like trance and metal and even most of pop musics
I will make a demo with complex songs maybe you hear the unpleasant sound of speaker
I bought power strip and no change in my sound 
I should say again that my sound quality is perfect except bass that hasnt detail 

I think other option is buy vacuum tubes
What do you think about this one?
