A customer shipped me this speaker kit for assembly. There are definitely some tricks to be learned as this can be a time consuming assembly. Hopefully this assembly log assists anyone looking to complete this task themselves. Here’s a link to GR-Research who is selling the cable kits.
GR research offers 24-strand and 16-strand versions of this cable. The included photos and description apply to the 24-strand version. 16-strand would differ only in its overall gauge.
This cable consists of 12-white and 12-clear individually sleeved conductors. Each color is braided in opposing directions. Each conductor is 19.5 gauge and consists of 7 strands of varying sizes (0.5mm x1, 0.4mm x1, 0.3mm x2, 0.25mm x2, 0.2mm x1)
Next I squared off the very end with cutters, barely trimming off any longer ends, again with the goal of filling all of the available internal space. Then I started adding those few wires I had pulled out while fine tuning the diameter and twisted them only around the lower base portion up until reaching that internal reduction inside the tube connector post. The result in the photo above shows the squared end with maximum diameter through the internal reduction and the maximum diameter up to that reduction. It does create a stepped appearance and while sliding the post over the bare wire that small internal lip will force those few extra wires around the base downward and they will automatically settle in their final resting spot against the internal lip. The above photo shows the end-result ready to have the tube connector post slid back on and soldered internally.
It’s certainly reasonable that you could skip some of that extra effort fine tuning the interior volume, and just push in whatever fits but my default position is typically to always put in the extra effort whenever possible. I wanted to make sure the customer had every advantage possible towards the best performance of his product. I don’t get paid for any of that extra time but I sleep well knowing I gave the best possible outcome, plus I never have to deal with re-doing or fixing a rushed job.
with the internal wires soldered to the inside base of the tube connector post, the remaining free wires get wrapped around the outside base of the post. The loose wires need to be spread out and flattened to avoid too much of a bulge but also to make sure that all of the available contact surface of the post’s base is directly contacting the wrapped wire.
Final thoughts on this kit:
Cables do matter. Connectors do matter. Each can have an affect on your sound characteristics. This is at least one of the best options available for speaker cables anywhere, and quite possible the best option in its price bracket. At the high level of performance offered with this cable, any differences in comparison with another truly top-tier cable would be preferential, and spending more beyond the price of this assembly would not necessarily get you better performance.
Pricing thoughts. Many commentators on various forums have compared this to the Kimber 12TC cable. It is a reasonable comparison since both utilize the same basic format of Counterbraided conductors of 19.5 gauge each, consisting of varying strand diameters within each conductor. The Kimber 12TC is a highly-praised cable even at its $695 price for a 6.5 ft pair. To price compare
