just think about it though. almost every other product industry is very reliant on actual specs to differentiate products (cars, tvs, cameras, phones, computers). you can apply your argument to eyes too, but there is definitely not this kind of conflicting/dissenting opinions or lack of some sort of objective performance measurement system about screens or TVs or cameras.
You should visit the car, bike, phone, video, etc forum equivalents of head-fi. The specs vs subjective testing is alive and thrashing everywhere there are enthusiasts.
