Pricey, but the lowest price around from a reputable seller.
There are many people that think that zip cord will work just as well as the expensive speaker cables. What nearly everyone will agree on is that copper oxide is an inferior conductor. Maybe the difference between zip cord and high end cables does not translate to a change in audio fidelity. The reason I pay for cables like the Audioquest Type 2 is because the reduced surface area of the solid core design means a slower rate of oxidation. Once it is in the wall, it is not practical to swap it out so my plan is always to do it right the first time. I have seen too many stranded conductors that are so oxidized that they don't even look like metal. The increased surface area of many smaller conductors is made worse by all the space between the conductors that will allow air to travel down the cable and do its damage. Individual small diameter strands are also far more likely to break from normal movement which is never a good thing.
I will not argue that premium cables will improve sound but I can say from experience that stranded cables oxidize faster which reduces their ability to do what they were intended to do (conduct). You can take a segment of Type 2 and strip the insulation off a decade later and it is still a bright shiny pink. Or buy a stranded cable with clear insulation and watch the color slowly change from pink to orange, to reddish orange over time. I never understood why people pay several times more for premium 6,7, or 8N stranded copper only to have their cables degrade each day. I have not figured out a way to keep my cables in a nitrogen or noble gas environment without suffocating in the process so I will continue to use cables that minimize the conductors exposure to air.
ProsHigher purity copper that will oxidize slower than many competing cables. You can double it up for not much more than the price of Type 4 while improving your AWG from 2 x 15AWG to 2 x 14AWG. This is important for the longer cable runs in an HT install. There is an excellent article titled "Speaker Cable Gauge (AWG) Guidelines & Recommendations" that is worth reading if you are attempting to set up your HT. I think it is still made in USA but have not confirmed it. The lower end G2 that I bought for internal wiring projects sadly is not (or perhaps it is just the box it came in that was made in China).
ConsCrazy expensive for multi-channel home theater use. With the introduction of Dolby ATMOS, I am going to be eating ramen for longer than I would like. My goal is to finish and enjoy my HT before the MSG gets me first.
