Upgrade amp power cable or not?


I just got two Monster HTS2000. Do I still need to upgrade the power cable for my amp? I have a Unison Research Unico Hybrid amp. What does a high quality power cable do that a stock pc can't. I can never understand the importance of the pc. If the wire in the walls are only as good as home depot cable how can a high end pc help? Does it improve current? Or does it reduse power line noise? Please help me justify a pc upgrade or not. Thanks.

That brings to my mind another question - how do I go about testing my AC to ascertain how clean it is? Are there standard testing devices (hopefully, cheap ones...) to easily find out?

Also, how do I find out if my equipment has some level of power conditioning in the power supply? I have a Plinius 8200 MK1 integrated.

Thanks in advance for any responses.
