A heckuva post.
I thought i was one of the rare few that wrote books in here.

The hardest thing about doing /setting up an A/B test is getting all the variables under control. As much as we think and try to tell ourselves that we won't have bias, there will always be something. For example, if the SPL output is not virtually identical between the two units being played back, then even with an A/B switch you will notice a difference that you might attribute to being the 'better' unit when the reason could come back to something as simple as a difference in signal to gain ratios for the units.
It is less distinct a factor to put your finger on compared to amps, but provides a huge difference, when comparing speakers that have different efficiencies.

Ultimately since so few people have the means to do true A/B testing, you have to use whatever method you have to try and ascertain a difference. It is the primary reason that drives audio myths, though in part unintentionally because of the limitations people have. Some wouldn't choose to use a controlled method though even if they were offered. It would destroy too much of the 'magic' for them.
