hi are the kef q8s good enough for surround duties for the marantz sr6012 av amp which i will be buying soon to replace a pioneer lx87 to get the newer surround formats? my couch is close to the rear wall and have 2 pairs of the q8s boxed up i had years ago and was wondering if they are good enough for todays soundtracks at the moment i have 2 pairs of mission 77ds as surround duties? i have kef 103 reference floorstanders from the 80s which i love for fronts and a kef q95 centre which i need to replace as its quite small and need something a better[any ideas welcome which would match the floorstanders?] also looking for suitable brackets which are tiltable? all input welcome for my centre and rears.
