Being a hobbyist and salesman at a high end audio shop for over 40 years I have tried various speaker placement systems. I was using the Wilson "WASP" for several years but find this to be very time consuming, enter Sumiko's MASTER SET, developed by John Hunter when he was the owner. I find this procedure to do an excellent job with some practice. They generally recommend Jennifer Warnes/Rob Wasserman "Ballad Of A Runaway Horse" which is good but I think there are potentially better recordings to use. The most important part of the process is getting the bass right, and there are recordings with more consistent bass runs, I recommend stand up bass on your album of choice. I would include a PDF that someone put together if I could figure out how. I am including a link https://www.audioaficionado.org/showthread.php?t=46634 to another website, hope that's ok, which seems to offer some good practical advise as to using MASTER SET.
