I'd say it is personal preference. Take a generic 16g cable, swap it, and determine if that particular cable upgrade makes a suitable sound improvement. If not, sell it, and use the 16g cable until you find something that does work to your preference. I don't believe the brand of cable makes much of a difference as the construction and noise abatement engineering designed in the cable.
PC manufacturers?
I prefer to buy my power cables used. I look for cables that are in good condition, well reviewed and fair priced. As I look at my collection, I have a mix of manufacturers and I wonder if that's a good approach...My question, should I find a brand I like and stick with it throughout my system or is reasonable to mix quality cables?
