Hi thanks to everyone who's advised on upgrades of my old system, which is for now at least, Arcam A85, Marantz CD 52 se, Mission 752s.
I say for now because one of the tweeters on he speakers has gone. Wilmslow are quoting for a replacement but will be a whole new faceplate, will need 2 so unlikely to be cheap. A few pairs of 753's on eBay, but they seem a fair bit bigger so want to make sure I'm not going to have matching problems. If its relevant then I'm on the look out for a P85 so I can bi amp too.
