Now that I'm into classical music again, I recently fired up my stereo system consisting of a Danon CD player, a Danon power amp and a pair of Celestion 100 bookshelf speakers. The speakers are on the wooden floor of my living room. The system sounds awful with no clarity. Every CD I've tested sounds dull. Is it because of the speaker placement? I used to place the speakers on speaker stands but don't have them anymore.
