AC Cable is there a difference in brands?
- Thread starter Kingsrule
- Start date
The differences will be in the installation!
Many electricians & audiophiles don't follow best engineering practices.
In N. America, Romex® will be better than the common way that 3 wire and conduit is done.
AC power conductors don't have a given sound. The differences in sound that you hear are in how your equipment handles the challenges that the AC power gives them.

Pretty hard to do an A/B comparison of them unless you wire your room with both and listen.
Since power cords can make your system sound different, I would imagine different A/C lines can as well. Just never done a comparison of A/C lines.

The main thing I like about the JPS Aluminata is the shielding. You can take a voltage detector and go up and down the length of the cable and get nothing. Of course I have JPS everywhere, including in-wall out to the Equi=tech.
Equi=tech actually recommended JPS. You don't see that often!

Fyi..you can take a voltage detector to a $5 stock Chinese sourced PC and still get nothing.

Yes, but we are taking about in wall A/C wiring. Romex does not have any shielding. Wood and Sheetrock do not shield RFI either.
True. If it was it would not be doing it's job. They are designed to detect the changing magnetic field around AC energized objects. I have not had good luck with those testers anyway. I prefer to use a volt meter to be sure the power is off.
Never the less a shielded cable will block RFI better than a non shielded cable. Which could be a problem with long runs like we find in house wiring.
I installed #12 stranded 2/C with grd..shielded, terminating the shield wire on panel grd. At the front wall I terminated it on two Hubbell hospital grade duplexes. Does it sound better? Of course it does! 
The cable is out there but sort of hard to find. Good luck with your search for the audio golden fleece!

Yeah and this becomes even more of a consideration when one considers that it has been proven house wiring acts as both an antenna and transmitter with regards to WLAN and other wireless broadcast technologies-wireless landlines-mobiles/wireless doorbells and similar products/etc.
The BBC (their technology research team-dept that are very knowledgeable and experienced) did a pretty in-depth analysis-study-report on this awhile back.
Not saying what is transmitted by house wiring is legible, but it adds to the complexity of interference considerations.

These two Hubbell HBL-8200HR receptacles have been in my systems since 1984 the grip is still as good as new, price paid back then $113.10 for a box of 10 installed many for friends, today the king is Furutech GTX D BUT back then the Hubbell HBL-8200 HR was a winner.

Ham radio operatiors sometimes use these radio receivers when searching for RFI interference.
Notes from Ham forums:
If all you want is a noise sniffer, look at the Tecsun PL380. About $45 from amazon, and it's a very nice portable AM/FM RX.
For general purpose RFI DFing I like the Tecsun PL660SLV
***************************************************
I assume that the reason some prefer the Tecsun PL-380 is COST. That's
unfortunate because for $60 more (based on current Amazon.com prices) the
Tecsun PL-660SLV is a MUCH better choice for all around RFI hunting.
I have been using the TECSUN PL660SLV for over a year now and it has helped
me tremendously in locating low frequency RFI sources. The Tecsun receiver
is one tool in my arsenal.

For measuring electromagnetic fields the Trifield® Meter Model 100XE would be a good choice for EMI measurements.
But the RF frequency range is tricky to use and it takes lots of experience to make any meaningful decisions about RFI interference.

The first time I ran dedicated lines I used Carol stranded copper water proof 10 gauge.
An electrician/audio friend said that 10gauge solid core romex would be better.
Was it?
Just trade offs as usual.
The Carol was darker sounding,the Romex was a bit more revealing.
I could live with either.
No real winner.
