To me it’s a thousand bucks, i have had several under $500 and they looked great but I have had noticeably less eye fatigue with binos in the one thousand dollar range. I prefer the view through meostars, which sucks because they are a little heavier than the other.There is definitely a point of diminishing returns in most things. I collect knives- it is about $300 to get to the "upper level" in noticeable quality. For binos I found that to be about $1,000 for the "upper level" that gives the "wow" factor and image pop. It is nice when there are companies like Athlon that break these price barriers and enter with a good value- but usually with some trade-offs.
