I have sensitive front speakers (Klipsch RP-600M 96dB). They came to life when I bi-wired them with these cables. I went from a standard 2 post hookup with gold plated jumper plates to banana plug bi-wiring. To my ears it made a noticeably substantial difference in sound quality. The cables sound very good right out the box. I can’t wait to hear what they sound like once they’re properly burnt in. I’m now hearing the crisp snap of a drum, the distinct plucking of guitar strings and the breath of vocals that weren’t as vivid as before. I know there are better cables out there, but for the price, these are an excellent value. I was pleasantly surprised when I pulled them out of the anti static bag. The quality seems good with a nice beefy heft to the cable. They’re also good looking with the red and black nylon braiding. The lack of technical specifications makes me suspect they’re most likely built in China. However, for the low price compared with other cables in this category costing up to 3 times as much, it’s worth the risk for me. It may not be worth the risk for you. I hope they hold up for a few years. Only time will tell. Either way, I’m very happy with my purchase.
