Hi. I'm in the market for a pair of somewhat high quality floor standing speakers but I'm not sure whats best for my money. I'm looking for a really crisp sound. Power but not overkill. Something that sounds exceptional even at the lower volumes. I wouldnt wanna pay too much more than 500 bucks for the pair. Also, I went to Best Buy to test drive some floor standing speakers by Klipsch. I'd never heard of this company before. Are they a good brand to consider as well?
