Nola Boxer, Ascend Sierra 1 nrt, Fritz Rev 5

All three in about the same price bracket and all huge overachiever monitors.

Any recommendations out of the three or experiences to relate?

Fritz is the only I've heard, and I can't imagine either of the other two being superior. I've been moving around in the small bookshelf department for a long while, and have heard many many monitors. The bass is plentiful and the treble is beautiful. Not super extended on top, but very enjoyable and musical. If you want hyper linear, this is wrong for you. But if you want deep bass, solid midrange and a natural sound, Fritz would be perfect imo.
