I can only comment on what shows up on HK auction websites since I scan though those sites on a regular basis for overlooked collectible CDs/SACDs. There is a very active audiophile scene in HK and those audiophiles hungers for audiophile quality music software. However, their preferences in music often differs to the audiophiles in the West....which is why there were SACDs of Air Supply, Kenny G, Vanessa Mae, etc. released. What would be a "must buy SACD" in the West may end up gathering dust on a store shelf somewhere in HK. Some of us may be excited about the upcoming Beach Boys SACDs from Analog Productions, but I am quite sure very few will care in HK. But that doesn't stop these SACDs from being imported to HK for retail sales. And that's how some "hard to find in the West" SACD titles ended up being available on a HK auction website or e-tailer's website.
Below is one of those "What is your latest SACD purchase?" thread out of, I believe, Singapore. You can see the differences in music preference....
