We got a LG 47LW5700 which I think is Costco's version of the 5600. It's too bad they had nothing between 47" and 55". It seems nice, the horizontal viewing angle isn't too bad. The 3D vertical viewing angle isn't good, but why would you watch TV/movies not at eye level anyway. Passive 3D ftw.
I got PS2 Jecklin 'stats that you can borrow for an indeterminate amount of time if you agree to refurb them.
Edit: I also have a good number of Lambdas, SR-X Mk3 Pro, used to have a SR-5NB, and still have tons of non-Stax 'stats.
Just got the SR-3N in the mail, plugged in and listened for a few secs... Stax, I am impress. Trying to decide if I should bother swapping in the SR-X Mk3 drivers.
Put up some pics of the headband. Perhaps it has stretched or whatnot over time, or you just have a small head. When I wear my Lambdas (Pros, Sigs), the adjusters are pretty much exactly at the halfway point.
