Thanks @ghdprentice and impressive systems. I had SF Strads and sold them a few years back. I miss them and was wondering if you had a chance to audition the Strads G2 or Amati G5. Perhaps a topic for a different forum.
You make a valid point about airports and planes being far from ideal environments for an audiophile experience. I wish I had chosen my words more carefully as I did not mean to use "on the go" quite this literally. My trips, as yours since you mentioned Japan, involve multiple hotel stays where I would rate the environment as good enough.
That being said, I've gotten my Bose NC 700 HP out of the closet and I'll give them another "go"
