may i ask did you used to use the forum name "oldphrt" ?Hi Doug,
Having just rejoined after a long absence, this is probably far too contentious to argue for or against. My own personal experience is that following 46 years of using the supplied cables, my dealer convinced a very sceptical me to try one. Within the week, I had bought two more. There is no fool like an old one, I know, but my ears were convinced. Like all equipment, is it possible that not all mains cables are created equally as I’m sure the negative views and experiences are highly valid? Mine are Audioquest NRG Z3. He wanted me to buy a niagra conditioner thing, but I drew the line at that. My dad was an electrical engineer, hifi enthusiast and assisted Dan McDonald in design elements of the BSR Turntables post WW2. Should have stuck with him as eventually employed 17000 in 3 factories making 80% of the worlds TT. His advice: route mains cables away from other cables, never coil/ loop them to avoid induction loops and put a decent fuse in the plug. Don’t know what he would have made of this discussion but there were no Wi-fi, mobiles, computers smart devices etc. filling our listening environment with interference in his day.
