The main reason for those unnormal high scores is that they were now calculated on spinoramas of back then which were strongly smoothed, not that they measure so well, so this cannot be used as an argument.
Thanks for clarification. Since the data/formula was built around smoothed measurements, hard to know if the more precise measurements follow the same formula.
How about JBL XPL90 vs JBL 4309 measured here on the NFS? The XPL90 is 0.1 points higher and if you just say they are identical, anyone buying the 4309 at $2000/pair should really get the XPL90 at a fraction of the cost.
