Mind boggling to me that in 2021 there are people on a high end forum like this one debating the value of audiophile cables. Every upgrade in cables I've made (from lamp cord, where I started over 40 years ago) has improved the sound of my system, in some cases dramatically. Power cables have made the biggest difference, interconnects the least but all have mattered. Not every "fancy" cable I tried resulted in an improvement - some were awful with my system, and the most expensive are not always the best although generally speaking more money buys better materials and assembly and more innovative design. The only way to find the best cables for your system is to listen and compare (as with other audio components), since cable performance is system dependent. This presupposes that one has learned what to listen for, which requires years of educating your ears by listening at audio shows, dealers, and to home systems. Currently using a mix of Hemingway Audio, Echole, Verastarr, and Townshend cables with great results. Audioquest (Sky), HiDiamond, Cardas Clear, Cerious, Harmonix, and Silent Source didn't work as well (although I have audiophile friends who love them) so I moved on from them.
