Now that I actually have some income, I think I will be upgrading my current set-up at some point in the coming months. I am currently using the Insigna bookshelves with a Sony 8" sub and an older Denon reciever.
I have been reasonably satisfied with this for a while, especially for paying only $180 for everything, but the auditory flaws are apparent to me even though I havn't heard much "high-end" stuff. The Sony woofer is rather boomy and not too musical, and the Insignias are not as crisp and detailed as I would like.
I am thinking about moving into floor standers because of the more even response across the frequency range (positioning and integrating a sub is a pain, and sometimes just doesn't match well), and not having to buy a sub. Also, my stands are crap and I don't want to spend more money on nice stands.
I'm thinking about saving up about $500 for a pair, because I am also saving up for college and an apartment, so I can't stretch this to several thousand

My question is, are there any decent floor standers for around $500? As in, you could actually live with them. I've looked at Klipsch (RF-10), JBL (L880), Infinity (BETA 50) and Wharfedale (Diamond 8.4).
I've mostly got two concerns, 1) How good do they sound? and 2) Can I use them sans woofer and get a full listening experience?
I know at this pricerange, I'm going to be skimping on
something, but can it still be worth it?
Thanks
