@samureyex I have a few thoughts I'll share with you, but remember systems and power filtration systems are different for each of us as well as personal preferences.
I agree 100% with @williewonka suggestions and I would recommend the next cord you purchase for your amp be one from Audio Envy which by the way should work very well on any of your components.
Power cords need to break in and be left in place (without movement) in order to know what they really sound like on any specific component.
I find silver-plated power cords (etc) to sound somewhat bloated, I don't mean to put down anyone or a manufacturer, perhaps I just haven't heard the proper power cord. If they sound good then go with them. When I purchase any type of cable that is silver I prefer at least 5N Silver, 100%.
