SR-009 would possibly be my top choice if it wasn't for the fugly and snappable plastic arc.  The rest of the materials are top notch quality, and the drivers are a work of art.
I voted SR-007mk2 over mk1 because of the strain relief.
The R10 cup milling, porting system, and floating hinge are all inspiring.  The cable is my fav feeling cable ever, I can stroke that thing all day and night.
My favorite thing about the Orpheus build quality is probably the earpad idea.  Pleather on the inside and outside to prevent micro leakage in an ESL, and velour on the part that makes contact with the head for ultimate comfort year round.  It's just a shame they used that cheap, flaky pleather instead of real leather...
One knock against the HD800 is how accessible the mesh is from the outside and thus susceptible to denting.
I'd add TH900 to my original list.

Few headphones have impressed me as much as the Yamaha YH5M

Don, how do these things sound? I've always wanted a pair but I'm always a little scared to take the plunge.

FR plots I've seen of it are not promising, so I'd love to hear your opinion as well, Don.
