I bought a nad c370 a couple of weeks ago to replace my Marantz pm4200 to go with some Mission 780s. The Missions have developed a fault and have been returned and refunded. So....what next? I found the Missions a little harsh at high end and at reasonably loud volumes. Any suggestions? I was looking at some B&W 602 S3s but I can't find them anywhere for particularly cheap. Or possibly some Monitor Audio Bronze B2s. Which of these would be better? And where can I find these quite cheaply? Would there be any other speakers I should take into consideration? Thanks for any help.
