Should I update my manufactures power cords?


I am using a AQ Thunder 2m (20A) power cord from wall to Niagara 5000. 

Do I upgrade equipment using manufactures power cords plugged into Niagara 5000? Streamer (HIFI ROSE), McIntosh MC611 mono-amps (2 plugs), McIntosh ref. preamp 12000st +12000C (one plug to preamp), McIntosh MEN220 room equalizer (1 plug). 

Please advise which AQ PC's to use and where or manufacture PC will work.

I conducted a survey a few months ago to formulate a group consensus related to the subject of premium power cords.

Here’s a link that provides the specific survey questions, a brief conversation between contributors, as well as a link to the results. This should provide some indication of the group’s adoption of this product category.

I appreciate everyones comments and the survey results. How do you distinguish between PC for use with each piece of equipment, for example, MC611 amps or hifi rose 150b?
