There are a very select few that can do this. There are almost none that can do this in a short time, say one visit to a home. I can certainly set up a room by ear, over the period of a month, but I can get it 95% of the way there by using test equipment. I can find the bass bumps accurately, the resonant peaks, the impulse response and know in a matter of minutes what needs to be done. I can figure most of this out by ear, but it's far more time consuming, because my ear is an estimation at best. However, once you get 95% of the way there through measurement, then you must rely on your ears to get that last 5%. There are some things that test equipment just can't do.
Let's put it another way--go to a high end show. There are a small handful of people that consistently get good sound on day one--with no test equipment. They are manufacturers or high end dealers with many years of experience, and there are only a few. These individuals do one room and it's with equipment they are very familiar with. I go in with test equipment and can get 7 or 8 rooms very very close very fast (within literally hours of the show opening), which is what is needed at a show. The rest of the people are lucky if they have things sounding reasonable by the end of the show.
I will mention one person, there are others, but this one hopefully won't stir up the pot. If it's Jim Smith and he's setting up a pair of Avantgardes for you--you are in good hands. He's been doing this a long time. He knows those speakers and he knows how they interact with the room.
Outside of this level of expertise there are two sources I would consider. One is the disc (and there are others) to assist in calibrating. The other is to seek out an HAA certified calibrator. I've been to their courses and we recommend them for all of our dealers.
