I'm considering upgrading my speakers to something like B&W 704s, possibly 804s or 9 NTs second hand. I've also been told to consider the Quad L range and I'm having a listen to the MA GR20s. I will add a CD player in a few months once the funds come together (just use DVD player for the moment). Up for consideration so far are: Arcam A80/85 Roksan Kandy MK III NAD 372 Marantz PM7200 / KI Signature version (struggling to find out what justifies the large price gap between these) Are any of these suitable, what else should I consider? Anyone know of 2nd hand kit around that I might pick up?
