Hi there. I am hoping the good members on here can give me some advice. I've owned my Kefs for a few years now, and soon will be updating my amp. At the same time I would like to upgrade the speaker terminals, as anyone familiar with these speakers or similar from the era will know they accept only the thinnest or cable. I'm currently using Cambridge Audio ultra micro but want to use some better cable. I am assuming the rear of the cabinet would need a larger cut out....but I'd prefer to take it to someone to do professionally or at least some guidance on the best plate/terminals to purchase and how easy connecting it back up would be. Thanks in advance. I am based in Kent so London is an option also
