I didn't try Yamahas. In fact, I wouldn't even care to try them among 10 headphones that cost $200. Sorry but Hifiman's even entry level HPs are not that badly tuned. What a joke!
You have two options Neo. Take the blue pill, you wake up in your bed and everything is normal, the Harman Target is untouchable, you won't have to worry about testing anything for yourself or listening to new gear. Agent Resolve will never hurt you again. You will be comfortable, happy even at times, and all those who enjoy headphones that do not meet the Harman Target will simply be mad, to be ignored, or in the worst cases, eliminated.
Or you take the red pill, have your own ears and judgement, and no longer think a single line in 2D space can sum up the audio experience, which is the sum total of waves intefrering spatially and in time, a fourdimensional array of oscillations interacting with your unique biology to produce an output. The people who enjoy wildly different sound signatures are no longer crazy, just different. The world becomes complex, and headphones.com reviews will no longer provide you with that same warm cosy comfort that all is well. You will have to venture out into the world, think, and i daresay feel for yourself.
So, which will it be Neo?
