Thank you for the insight!
I personally use CDJapan for anything Japanese. I live in Calif so speed of shipping and shipping costs from them is real good. If the Japanese decide to release a version of anything you can bet it will be good. Keep in mind SHM (Super High Material) discs do sound better , albeit barely then a non SHM. Also some audiophiles refer to it as a gimmick as they are still 16bit/44.1 unless it is SHM SACD. Blu Spec CD2 is another version like SHM CD. You are correct, all Japanese releases usually sell out pretty fast, sometimes they will re-release but not always. I just purchased the Rolling Stones Mono Box Set SHM CD from CDJapan and I love it. It's good for newbies to ask questions, we where all newbies at one point and I am certainly still a newbie in some audiophile topics.
