I need advice on purchasing a speaker system. I am going to pair it with maybe an Onkyo 502 receiver or a Denon receiver. I have been considering the following small speaker packages: onkyo 240 series, polk rm6800, athena point 5's, and athena micra 6's. I know the best way to decide is to listen to them but where I live I can't find a place to listen to these. Any opinions or advice on these would be appreciated.
