    Local audio shop's brand, but no idea who made it for them. Got a "good deal" at a couple bucks a foot. Bought it as much for the jacket which was flame retardant and supposedly formulated for easy pull in wall cavities. I more and more gravitate towards Home Depot and Costco for allot of different things. Given their volumes, any faulty product would be a huge headache and their stuff just seems more reliable IME.

      I use Carol SJ cable for speaker wire a lot! I've also used Royal Electric, ProCo, and the HD variety that is not Carol.

        The lengths I have are only about 8í, but I didnít know dats could read that low; I do have one. Thanks Chris. Might be fun to do some comparisons (later when I have some time).

          Are there any advantages (if any) over the Monoprice or Mediabridge 2 conductor in-wall speaker wire
          SJ is very durable in applications where it's exposed to foot traffic, like pro-sound PA speakers. That's the only time I use it.

            FYI...a couple of people have mentioned "prettying'" up some of these basic wires with Tech-flex, cable pants, etc. I just recently found out about this idea and created some that came out great. For anyone interested, and didn't quite know what the posts were referring to, here is a good video and it is from a frequent forum contributor also.

              I don't know if I'll ever not giggle at the words "Cable Pants".

              I use off the spool lamp cord from the big box hardware myself. I'll pick the gauge for whatever the application is, depending on length of run, impedance of speaker and power requirement.

                So at Chris' advice I ran a Dats test of the two cables; the fancyish one being an Analysis Plus oval one (with bfa bananas attached) and the other the new CCI 14/2 inwall, bare ends. Both are about 8ft long. The far end was open for the capacitance test and shorted together for the inductance/dcr test. It does not appear that Dats tests low enough to get an accurate capacitance or to recognize either as an inductor. There is a bunch of different data generated for the CCI in the cap test that I do not see registering for the AP cable. I will attach screenshots. Anybody smarter than me (all of you), please take a look at the results and feel free to let me know if any of it indicates anything of interest, thanks.

                Also, I called the AP wire "oval one", it is actually "clear oval", and also spec'd at 14ga.

                      To me the capacitance test resistance curve on the analysis plus cable looks like I measured a capacitor.

                      Subjectively, the CCI sounds significantly less bright; especially since these speakers were voiced on the AP cable, so the result is probably extra apparent. I have constantly battled the voicing on these to tame brightness but now it sounds much more neutral on all tracks that used to cause ear fatigue. I almost now feel I could stand to elevat the upper end a touch. Very interesting experiment.

                      I know this is subjective but it is so apparent I would put money on It that I could pick the cable in a blind a/b..

                        Look at the resistance measurement from your inductance test. While neither are above the measureable threshold, the CCI cable is certianly more inductive, reaching above that 0.2 ohm mark at 20kHz. We're talking a difference of about 0.15 vs 0.22 at 20kHz, which I wouldn't call significant at all, but it does indicate a measureable difference in the cables.

                          I noticed the impedance rise at the top end as well being a slightly higher on the CCI, do you think that could likely be because it is a twisted pair instead of two flat conductors stacked on top of one another like the analysis plus?

                          Kind of fun analyzing something besides speakers for a change

                            I came across a CCI spec for its 14 gauge speaker wire: 18 nf / ft at 1 Kz and 2.6 Ohms resistance / 1000 ft. At 8' that puts the total capacitance at .144 uf.

                            Good think my hearing is shot and the HD lamp cord does just fine for me

                              What Toid didn't tell you in the video, is that you are supposed to use a hot knife (or old soldering iron) to cut the techflex so that it does not fray.

                              I also like to invert/funnel the ends before I insert them into the end jackets.

                                Thanks for the tip! Yes, I spent a lot of time trying to tuck my frayed ends up into the pants.
