Hi, I'm considering the Yamaha RX-V440RDS AV amp and have a few questions. 1- What do people think of 6 channel surround soundspeakers? 2- What 6 channel speaker system for around 200 quid would you recommend? I have a very small room and don't need things to be loud! I prefer good sound at low volume. 3- The manual for the RX states that hooking it up to a 5 speaker system is not recommended- has anyone tried this? Thanks!
