I have a thought Bruce. To make the job easier when doing AB test, I like to hear the same thing over and over again. After all, you don't want to hear a note in equipment A and note two in equipment B. So how about we take the right few seconds and loop it for 3-5 minutes. It would be nasty to listen to but we are not trying to enjoy the music, but figure out what's wrong with our gear.
