Updated: Got my speakers 2 weeks ago. Drove it with a Parasound amp. It really sings well. Have not done much movies, but 2-channel music is much, much, much better than my Klipsch setup. Earlier, if I sit near the front, it sound OK. But as I moved back further, the sound fell off quickly. With this set, every where I sit, it sounds similar. high/mid/low all improved. Couple this with my BIC sub, I can finally have a setup that would allow me to enjoy music and still can shake my chair with movies. Heck, I can even do Karaoke with it :-)
This is floor-standing, so it's not fair to compare against a bookshelf, but cost/quality is much better.
