So many of you know that I am cynical about mains cables.
It's not that they don't make a difference, it's just that it's hard to predict how large that difference may be.
It depends on your mains quality, what else is on the ring that can put dirt into the mains, and also airborne interference from wifi/4G affecting cables.
These Rega cables are well made, well insulated and well screened.
They make most systems sound better and I am happy to sell them to you on sale or return basis within one week.
Buy them and if the difference isn't impressive then return them in the packing in new condition and we will refund the £ 95
