I'm new to many of the brands of speakers out there. I've been trying to educate myself reading posts in the forums and by reading magazines. It appears that Definitive Technology is reviewed well in the mags, but people in the forums don't appear impressed. I know I really should let my ears be the judge, but why is Def Tech not well regarded? Can someone please recommend good speakers in the $2500 range? Also, up to what size room will bookshelves be appropriate? Thanks for your help.
