The ROOM has so much more influence tham (one poster above indicating '10,000 to build') vs say 1,000 cost to build. Consequently, the 58k speaker will potentially sound WORSE than the 5k speaker in that same room.
And A vs B is the ONLY way (as in EVERY subjective (the definition of TASTE) competition) to find out what you LIKE better (there is no "IS BETTER" when it comes to TASTE or any other subjective field). And THAT opens the EMOTION
AL part of what the OP describes. The speaker is NO different than any other 'luxury' item. The jeans is said to be of higher quality and certainly cost a LOT more to make (they select great thread colors :-) just like that 'fancy' speaker. Yet there is a market for those jeans. The ROLEX by the way started out as a measurably superior PRODUCT demanding a higher price due to quaity. And the MERCEDES demands a (slightly) higher price for the same reason. But for obvious reasons not 10x or 100x the price of a similar Cadillac. So that GREAT (in the eye of the beholder) 58k speaker might be worse 5.8k and compares well to the 'lesser' 4k speaker. Just like that that 200k Ferrari compares well with a 80k Audi. Factor 2 to maybe 5. In the Audiophile world, the 'overpriced' (pixel dust) factor is more like 10x to 100x. And all of that is well known, and applicable to most other 'esoteric' (100% subjective, non measurable) fields. And A-B are most definately frowned upon in that universe (no one likes bubble busters). So the best way to NOT fall victim of pixel dust overspending is take 2-5 (or 2 then 2 then 2 as I continue to do it) speakers home to YOUR room. Listen to them A-B for days or weeks. Then pick the one you like best. Start over with the next. A-B. You will gradually come to your ideal (the ONLY one that counts) and likely spend 1/10 or 1/100 of what others spend.
