Go to the Ocean Mall, I believe it is called in Kowloon. There you will find high end audio stores all on the same floor with unbelievable equipment, but not necessarily great listening environments. In most cities you have to drive all over town to see all the good stuff, but in that mall there were three or four great stores right near each other on the same floor. However, this was ten years ago when my wife and I were on vacation, but hopefully things haven't changed much. Take a sandpan boat tour through the harbors to look at the junks that people live on. You can catch one near the Jumbo restaurant which is a floating restaurant and a tourist trap.
