Ah! Well done on the purchase! I went up there once before. The hifi equipment up there looked like high end stuff. AV Hospital used to be on Shatin as well long time back. I got my Pioneer SACD DVD/CD player there all those years ago. Old tech now, but still going strong!
O2 had their service centre there in the days of the Atom. Looking back the Atom had a lot of issues, but I still loved it!
