Hi All, I would very much appreciate any advice on upgrading my home cinema with regards to the sound aspect. I have a Panasoinc 37" plasma screen, a Denon 1930, a PS3, a Panasonic DVD/HD recorder, my speakers are the original KEF eggs and my amp is a Yamaha (not sure of the model). I was thinking of spending about £500-£1,000 on upgrading the sound system but am not sure whether to upgrade the speakers or amp or both. Which would have more impact? Any ideas anyone may have would be great. Cheers for now.
