A Sterephile test CD and a Radio Shack meter for the bass works well, a Cardas Disc for set up (includes a "walk about" which I find helpful), and I use an Opus 3's "Depth of Image" to fine tune, as well as other ordinary disc's with which I'm very familiar and which have borderline problems if the room set up and the electronics are not ideal. In the end though you're still likely to have some compromise somewhere. The bass can be a bitch to get smoothed out as there usually are some room problems you can't correct.
