I actually know nothing about it. I also meant tilted downwards with some spikes to create or balance the signature. Doh. I'm just regurgitating this information from a thread, I think it was the ES5 thread.
I still stand firm on graphs being ultimately useless in decision making besides giving us a small idea of how the can will sound relative to another. Data and measurements aren't, and doesn't represent, everything.
I agree on this point to an extent. Personally I agree on the matter that ultimately you should make the decision based on listening to said gear. But this is not always the case either in terms of sources (high output impedance) paired with said gear. That is where I won't agree on this as I've heard what such gear does to sensitive IEMs and headphones first hand and ever since that won't stand for it.
