I currently own a 70s vintage pair of Ohm-H speakers, which I have never been happy with. I am thinking about a system upgrade and anticipate purchase of something like a Yamaha 1400, or comparable NAD or Denon. I am interested in speaker recommendations. I would like to begin with a pair of new floor-standing speakers that would pair up well with these receivers ... but ... I need more bass separation (but not necessarily more bass volume). Can I do this without a sub, and if so, what would your recommendations be? If I will need a sub, what would your recommendations be, and would you still recommend the same speakers (if going with a sub, does one still need the same caliber of main speakers ... or can one maybe go back to bookshelf speakers)? I would say that my price range is probably $700-$1000 for the pair ... and $700-1300 if a sub is needed.

My listening patterns and tastes: wide variety of music ... little bit of jazz, little bit of show music, but I would say 80-90% classic rock, current rock, and current day stuff like Creed, Red Hot Chili Peppers, Counting Crows, Matchbox 20, Third Eye Blind, etc (no rap). I live in an 800 sq. ft. apartment.

Thanks for your help!
