Power cable education needed


Hi everyone. I need some education on power cables. I have been reading that a good power cable is vital to a good sounding system. If that is true wouldn’t the companies the make the components include a good power cable to insure their product sounds the best that it can ? Should I evaluate the power cables in all of the components in my system?

Any recommendation for make and model, and price of package?

Sure thing.  IK Multimedia does a solid room analysis package with a mic included.  Little slow on shipping right now, thanks to COVID, but...

@jerkface, 

Yes thanks for the reply. Is it REW with the UMIK-1 you are talking about ? 
Wiring is like a chain. The chain is as good as its weakest link. Since all your house is wired with a Romex cable of appropriate size (typically 15 - 20 amps), adding a much stronger link into the middle of it does NOT make it any better.


The wiring in most residential construction is solid wire which has less resistance than the stranded wire that is used for power cords.
