Yes, I know how good a speaker sounds is mostly subjective, however, I am looking for some basic input as to major differences to be expected (i.e. are some regarded to be better than the other) between the following: Paradigm Studio series (100's for mains) Paradigm Monitor series (11's for mains) B&W 600 series (604's for mains) JM Labs Chorus or Cobalt series (725 or 826 for mains) Rocket (750's for mains) I realize there are some jumps in price on some of these...my friend is dealer for Paradigm, and I'm not too familiar with the JM Labs pricing (heard good things about them though). Right now I have a Marantz 7300 and will probably add an amp...possible upgrade to 8300 when/if it comes out. Any input is appreciated. Thanks.
