Sell towers for bookshelves?

Thanks for the feedback so far. I'm just sort of feeling around as I'm curious as to how much I would have to spend for a significant upgrade in sound quality in the speaker department.
Meiwan, yes I do believe that the towers may have too much botom end (due to their 8" woofers) in a smaller place, which is part of the reason I was thinking about bookshelves. I will not replace the towers until I can afford something of significantly higher quality, however. So you are saying that for the increase I'm looking for I would be looking to spend around $1,000? or more? Thanks for this help.

And as far as other advantages over the towers I have read that of bookshelves and towers of the same price, bookshelves will generally be of higher quality. I am looking for more detail in my music now, and am willing to sacrifice low end (especially if I cannot play music as loud at my new place) so I figure bookshelves would be something to try.

I'd agree that to get a good increase you'd have to spend a bit more.

But my main advice is to get into the new space first. You never know what it'll sound like and what you need until you've got everything in there. The room is the most important component IMO. Well, the music is, but you can't really improve that.

Yes, sell the towers and get a pair of ProAc 1SC's to put on stands. As others had mentioned, the new room will need analysis before you will be happy. Be patient. Best to find a dealer that will loan you speakers to try with your gear in your new room. The latter approach is the only one that will give you a real sense of what is possible.
