SR's should be nice. Ive seen them for a fairly decent price around the internet.
The QSD's I've heard have really sharp highs, but are a really good set if you like the screeching highs.
As for amps. It kinda depends how your running your system, as in passive or active. But I'm assuming your going to need something above the 100+ RMS range. So your still gonna need a pretty powerful 4 channel. Or a decent powered 2 channel.
EDIT: Just realized too that obviously a "high end" audio store is going to have insanely jacked up prices.
You can get your fancy $1000 showroom speakers for $580 free shipping brand new.
