Hi All Looking for suggestions to replace my ageing Castle speakers after one of the Avon cones finally died a death. The system currently consists of:- Castle Avons (L+R) Castle Keep 2 (Centre) Castle Dipole (Suround L+R) Castle Durhams (Rear Suround) CAstle Classic Sub (run of a B.K. Electrons board) They are currently being driven off a Arcam AVR500 and i intend to keep this. The room is about 5m x 4m and the distance to the TV/Centre is 4.2m I am thinking of the following:- M.A. New Bronze or Silver Range M.A. APEX I also have a possible option on the out going M.A Gold GXC150 and GX200 for the front and keep the rear set up as is. I am looking to inject a bit more life into the system. Budget is up to about £2k to do a full or partial replacement. What would people suggest i listen too or do with regards a full or partial update?
