Now I know my AV receiver is out of it's depth a bit with my speakers - this will be addressed at a later date. However, my question is about rear speakers. My front three are now Vienna Acoustics (Mozart Grands and Waltz Grand centre). I'm looking to change my Monitor Audio R90s. Because of reviews and colour(!), I'm edging towards the Apex A10s in gloss White. Would these gel with my front three or should I finish the VA family? Any other suggestions??
