Jeff,
It looks exactly the same as the US product...that much I can tell.
I would venture into the Japanese SACDs although they are asking for a steep price. I only sampled the regular CD layers of the M1, M3, M6, M9 but I could hear a huge improvement over any of the previous versions. Strings are velvety and sweet, woodwinds bright and have much more presence, all in improved balance.
John,
