Avico, you said that you have tried power cables and did not hear a difference but you did not say what power cords you have tried?
Respectfully,if you have not tried the ones I've mentioned then I think you are doing yourself a disservice.
I too use to feel powercords didn't make a difference until I had the opportunity to hear really good ones!
The biggest mistake many audiophiles make(and you can tell by the responses to this thread)is throwing more money at components when the biggest problems most systems incur that make them sound dull and lifeless is EMI/RFI,power conditioning and vibration control.
Having good powercords and a good power conditioner can improve a system dramatically! without changing components.
