Here we go again: $5000 budget, which HT speakers?

I'm sure this is 'yet another' semi-newbie question, but I have $5000, want a good 5.1 setup (or could go powered fronts), and have: Yamaha RX-V1, Pioneer Elite 52", and about to buy Pioneer DV47ai. I've listened to & liked the sounds of several main speakers: Definite Tech, JM Labs, Sonus Faber, Vienna Acoustics...

Any help appreciated... Any cable suggestions also appreciated...
