A couple of things if I can be so bold. All cables used in the test should have at least 200 hours of break in. Preferably using a break in machine but break in using music is acceptable. All connectors should be cleaned and wiped dry. The test system used should be checked for correct Polarity using XLO Test CD, in phase and out of phase track. Preferably the source(s) CDs or whatever should also be checked for correct Polarity. The source should be familiar to the listener. The system should also be familiar to the listener. He should perhaps be allowed to use his own CDs for the test. At a minimum the listener should be allowed to familiarize himself with the sound of the test system prior to testing. Kind of like warm up pitches in baseball. Loudness should be controlled. Time of day should be controlled. Early morning on weekends is best, or late at night. Testing during bad weather should be avoided. The number of consecutive tests that must be passed should be minimized. The number of people allowed in the room should be kept at a minimum.
