That's a great point. I don't usually go that far no. I think just having any artsy fartsy 3D audio FX is immediately detrimental to the original "vision" of what they wanted things to sound like. Type of headphones and speakers not so much because a big part of their job is actually to make it sound good on as many different types of speakers and applications as possible. If your headphones are good and have a fairly flat frequency response then it'll do a good jobDo you also stalk outside their homes and knock on their doors to find out exactly what equipment you need to use; because surely you must understand that you can't just use any old headphones, only the ones approved by the sound engineer?
But what do you do if they didn't design the sound for headphones, only regular speakers of a very particular setup?
