Hi I've been shopping around for a new hi fi system, and I am interested in buying B&W speakers. I was originally going to go for the 602 S3 shelf speakers, but I have now given thought to perhaps picking up the 603 S3's. The guy in the shop i went to was offering a pretty competitive £250 for the 602's, and £500 for the 603s. But he was suggesting I pick up a harmon kardon amp to play them though, specifically the HK 675 £250 again. I've not managed to turn up much information at all on HK amps let alone the 675. I was personally contemplating getting the Rotel RA-01/02 or the Marantz PM7200 before he mentioned the HK amp. Would anyone be able to help me with a bit of information on which amp would be good to power either of these speakers, and also if HK amps are any good because I have not been able to turn up much on them at all. I listen to a lot of bass heavy music, but I don't want voices/treble to suffer as a result of inferior components, your suggestions would be greatly appreciated. Thanks for the help.
