I used a Panasonic SA-XR57 as a stand alone receiver, an Outlaw 990 and amp as separates. The speakers were crossed over at 80hz to a pair of NHT U1 sub woofers driven by two Outlaw M200 amplifiers.

My room is heavily furnished. Hardwood floor covered with a Flokati rug. All windows have heavy, light blocking pleated shades. There are 3 large bookcases filled with books on either side of the listening chairs.

I compared them to Dynaudio BM5a professional monitors and Genelec 8030a monitors. I also have several other speakers at home to compare them to, but am loath to do "head to head" comparisons as what might be good for me might not be good for you. What I can say is that at their price point (and beyond) the Outlaw Bookshelf is a serious contender.
