Hi guys, i'm now in the market for a pair of new/second hand speakers to go with my system due to one of my mission 780's blowing a driver. Currently i'm running the 780's as fronts, Kef Q6 ctr Qcompact rears and psw2500 sub. All driven of a yam A2 and Toshiba SD9500. Now i've thought about getting another pair of missions. However i did intend to use the fronts for music with the SD9500 and mabe buy a primare A30.1 amp a year down the line. Question is any ideas what bookshelf speakers will be a good replacement for the missions? Plus ideas on future upgrade to demo to see the difference?
