You all don't know me from anywhere because I'm a lurker supreme, but I really appreciate the measurements and discussions here.
About me: I'm what you all would term a sound science 'tard (I spend a lot of time at HydrogenAudio too).
My current listening rig is an O2 + ODAC driving the HD650. I also own an HD598, AKG K701, and Shure SRH940. I'm looking to upgrade to a better transducer, and thanks to your measurements I've been been able to eliminate from consideration headphones that have peaky, uptilted treble response. Despite having (minor) high frequency loss, I don't experience boosted treble as more detailed and so it's nice to have a reference to go by so I can avoid similar mistakes like my 940 or K701 purchases.
