Due to the lack of space on my tv rack i can only fit an home cimema amp under 18cm so i have been looking at the smaller amps Onkyo TXSR578 or the Yamaha RXV667 , i was thinking of the Kef KHT2005 .3 or the Cambridge audio minx 325 or the smaller minx 215 , the wife does not mind as long as long as the speakers dont over power our room
