You guy should go and ask Tyll for his option (or to reconfirm it, actually). No need to run in loop on the same arguments. Fang has taken his time to tune RE262, and more so on RE272. If he think RE272 is worth the $100 more because the extra time he has spent to get it right, then that's his decision. None of us has to agree or disagree about it, especially since both have been discontinued. Regardless, same argument can just as well be applied to SE530 vs. SE535, 2X-S vs. K2 SP or PFE022 vs. PFE122 (to a lesser extent). I am sure there are other of such example out there and I don't think you can get everyone to agree unanimously that the price increment is worthy / unworthy of the difference in sound.
