I've been significantly upgrading my system over the past year and have so far avoided upgrading my speaker cable, I've just always been sceptical when it comes to the benefits of expensive cable. I'm running a Rega Brio 2017 with Tannoy Precision 6.1 speakers, using the cheapest possible speaker cable from richer sounds. I've decided it's time to at least give mid priced speaker cable a try. I've been looking at Audioquest slip 14/4 as a possible option, it has the option of being used for biwiring which I wouldn't mind trying. Anyone got any other mid priced cable recommendations? It would be to listen to alot of seventies vinyl acoustic music, also seventies reggae,
