Just curious how you went about it rather than just do something less formal. I generally don't bother A/B any more, found it very time consuming and hard to do by myself, altho met someone kinda local on one of the forums a few years ago when I was living in the SF bay area, and we got together and tested 3 different pairs of similar speakers (all mine, he was interested in buying the same speakers), not particularly blind, no eq, with crude level matching and somewhat quick switching (I had a an A/B/C switching box)....and we found it somewhat inconclusive as our opinions weren't the same and it somewhat depended on what we listened to (all 2ch music).
I have quite a few speakers and subs spread over 4 multich systems and one 2ch system, and I diy'd the last several subs. I just move 'em to another room rather than get rid of any, hate the selling process and none deserved returning particularly.
Sounds like you're building a very nice system and I would love to experience Perlisten but not about to put down any money/effort to do so. If I had better test gear, perhaps something like the Van Alstine ABX Comparator would be interesting (but not interesting enough to buy one!).
Didn't mean to grill you, just more curious what you did and how you went about it.
