I just bet most audiophiles do not have their listening areas treated properly and so frequency response would be all over the place anyways.I think this is the reason people search for and talk about system SYNERGY, toe their speakers in/out etc . The other totally misleading thing audiophiles tak about is "dispersion " . This a a TOTALLY meaningless characteristic for 99% of serious audiophiles.Why? cause we all do our serious listening by ourselves and therefore sit in the sweet spot.So between treatment and positioning etc we can get good sound as long as the speakers are reasonable well designed and have good drivers. The better the design and drivers the easier it is to accomplish( usually).
