I'm hoping to do some single-blind cable testing. I don't want to use an ABX box. When I'm doing sighted listening comparisons, I like to listen to a particular setup for about five minutes, with several music selections, to get a feel for it---so I want to use that type of listening during a blind test. Because I won't use an ABX box, I will have a friend hook up a cable that is unknown to me, and do this several times while varying the cable choice according to the following protocol:
- I will select two cables to be compared to each other
- one will be called A, the other B. The assignment will be made by coin toss and will be unknown to me
- the friend will, by coin toss, select the ordering ABAB or ABBA
- on four consecutive runs, the friend will hook up the cable as indicated by the selected ordering
- I will listen for as long as necessary to each cable. In my recent sighted tests, I tend to feel I need about 5-10 minutes with various music selections
- I will be required to identify whether the protocol was ABAB or ABBA
In addition, but this is not necessary, I could comment on the identity of A and B. I could say "A was clearly the better cable", but I am only required to prove I knew the selected ordering ABAB or ABBA.
We will only do one trial to start, to get a feel for the situation. Doing 20 or 30 trials will be time-consuming, especially because I feel that I'm sharpest if I limit the number of critical listening sessions I do in a day.
