Do Japanese market CDs usually sound good enough that it's safe to buy them on spec? I ask for two reasons. First, I see a fair amount of recommendations for Japanese releases. Second, I lived in Japan for several years (before I was aware of different releases and mastering quality) and know the Japanese to have a keen eye for quality. Slop generally doesn't have a market there, and especially not enthusiast items. A local music store has a Japanese import Van Halen s/t that I'm considering.
