Which is for me, floorstanding, or books w subs?

For that budget I would urge you to look into a used pair of KEF Q series speakers, Q30 or above if you think floorstanders will be the solution.

Headphones are your best bet on your budget.

I was quite impressed with the Boston Acoustics CR-8 a few years ago. Whatever its successor is today, it's probably also pretty darn good for the money (which should be within your ballpark).

Hi guys, the gentleman has already told us what he likes, Klipsch. I would suggest a pair of Hersey's, usually around $325 to $500. The trade off here is the bass may not go as low as the Fortes. Klipsch has several other models too I think in the RF line. You should visit your local Best Buy to hear them. I would seriously suggest a pair of Athena AS F2 or 2.2's. Efficient, and excellent bass response. Used most likely under $400. Check Audio Advisor to see if they still have some. They were $300 a pair or so at one time. The Energy line of speakers are made in the same factory and are very very similar to the Athenas.
You can find used Klipsch anytime on AG or Ebay and other sites. They make a bookshelf or two with pretty good bass and and a sub can be added later. By the way they play at rocker levels too. I hope you don't have a lease. Most of those floor models can cause some problems above you as well as next to you and below you. Some models of Klipsch can get peaky or bright. Listen to them first. If you want it loud and clear and clean check out the Klipsch. With the receiver you have and some plain Monster Cable or Kimber 4PR it should be a nice sound.

In your price range a pair of Polk Audio speakers such as these is what I'd look at. Not these specifically but in the ball park. Oh yea, no affiliation with the seller I just think Polk speakers are good for what you want.
