What's Wrong With ROMEX??

Would appreciate some feedback and comments about a question I have regarding dedicated power supply lines.

I just got off the phone with a very well respected tech who's known by many audiophile electronic engineer types around the country. We spoke about whether it made much sense to invest a boodle into "big name" dedicated power cables that would run from my circuit breaker box to my stereo. Or, would a couple runs of plain old 10 or 12 guage romex be good enough?

He said there's a lot of hype and audiophile insecurity out there. That is . . . many believe that if you don't spend a lot on a tweak or piece of gear, it therefore can't be good. Bottom line: standard romex would be fine. However, he did recommend getting high grade "spec" sockets that will grip the business end of a power cord. He also thought a decent power conditioner was worth the money.

I'd appreciate some comments and opinions. Thanks
