FRM, They can deliver as late as 7 PM here in my corner of earth (46.2857° N, 119.2845° W).
It's all good, they got here at 11 AM this morning. I am listening right now and am very impressed. Incredibly deep, solid, tight, bass. Reminds me of my old Stax kit. Treble is smooth and extended, can get intense if the music calls for it (First Cut: Saor/Free/News from Nowhere and then into Eistigh Liomsa Sealad/Listen to Me/Saor Reprise by Afro Celt Sound System, album - Volume 1: Sound Magic.
Midrange seems just slightly closed-in or congested (?) but female vocals are sweet.
Currently using my iFi iDSD (orig) for DAC/HP amp and have the volume at 12 o'clock which is ~85-90 dB (just a WAG). Is there such a thing as break-in with a planar magentic headphone? If so how long can I expect it to take?
More as I listen.
Again thanks, dB Cooper! Love getting high quality, high-end gears for a great price.

PS - So far the weight and clamping pressure don't bother me at all. Time will tell.
