Am looking at upgrading my speakers as the ones i have are 17 years old Kef C75... Option 1......NAD M3 with 804s or 805s...is there much bass difference between these two speakers (present amp is MF3.5 and NAD c542 CDP) Option 2.....B&W 683 floorstanders with NAD m3 (present amp is MF3.5 and NAD c542 CDP) The price difference is quite large and i wondered if the sound performance would be as large. I could keep the MF3.5 and just change the speakers and i note that Andy has 805 speakers himself so should be able to give a good appraisel of them Just one more question the C542 CDP has been around for quite a while now so has this now become the week link in the chain.......regards ....ian
