Hi all. I could really do with some advice. i have ben running a Yamaha RXV371 Av receiver with the Canton Movie 80CX package for a year or so. I have now decided to upgrade the speakers to Wharfedale Diamond 10.3's all round with a Diamiond CS centre and keep the existing Canton Subwoofer. On looking at specs and playing around it seems the RXV371 only controllers crossovers globally, do you think this is going to cause me a problem?? or should i really be looking at upgrading the receiver?? Any advice would be of great help as im going round in circles. Thanks in advance hope you nice people can advise.
