I'm glad you like the sound of them. Before you decide to keep them make sure all your neighbors like the sound of them as well. It's not all about you, ya know.
I didn't do anything too crazy with your notch filters in that B&K pre-amp but you should go in there and set everything back to zero. It was only a minor adjustment but it was speaker and placement specific.
Some guy at work just mentioned the other day how he thought a Bose Wave Radio had impressive bass ... I should buy him some ear plugs and send him to you.
