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?

Don’t forget to upgrade the windings in all the voice coils of each transducer/driver, and each inductor in each crossover. Everything in the system that carries electrons needs to be Quantum Tunneled to make sure there’s no atomic breakdown or electron traffic jam...

Or China Syndrome WILL occur.

You’ve been warned. All or NOTHING!

" the quality of the power cord matters just as much as the quality of the amp"

@Ronboco, you may be a newbie.  Please don't listen to Miller.  The above is possibly the biggest load of hogwash he has ever written.  Being over-generous to him, this is at best a maaaassssssiiiivveee overstatement.


@jerkface,

I appreciate your input and I’ve learned that treating a room is critical to good sound. I do have panels from vicoustics and gik on the walls. Have a look and tell me what you think. My room question was referring to the fact it’s not a great room really for a high end system being 2 story and open to other areas. I was wondering if there comes a point when continued upgrades would become fruitless because of the room.
