Bookshelf speakers $500 -$700

I agree get some actives and ditch your amp.

I recently picked up a pair of PSB Imagine Bs that I'm pleased with. They are rear ported and will do best when placed on a solid stand. I have them paired with a SVS sub and cross them over at about 60.

When deciding on bookshelves, placement proximity to the walls is important. How close do you intend to place them to a wall? Also, do you already have a sub? If not, that could be a factor depending on how much bass you want from the rock.

+1 Silverline Minuets. Heard them at a show several years ago and was astounded as was most everyone else in the room. Imaging was first rate, and they even did a credible job of placing a stand-up bass in the room with great weight, tonality, and micro/macro dynamics. Best of luck.

Consider the LSA1 monitor. Now that they've gone Internet-Direct, the standard edition falls right into your price range.

Stereomojo review

The best available at that price are,as others have said, are
the Silverline and Rega 1.
Silverline a bit better all-rounder, the Rega is superb on acoustic music
