Good question about an audiophile presence in China. I really don't know. I worked all over the US and never bumped into one randomly. You know happened on one while working in casual conversation. Audiophiles are a rare breed. So, it is not surprising I never ran into one in China. One would have to seek them out.
I'm not a shopper... certainly not when traveling. But if I was, Singapore would be where I would go. I used to make a game of exploring the most convoluted paths I could take for miles through the shopping malls. Starting on the lower floor of my hotel... through the tunnels, put through several floors of sky scraper across a cat walk into the mall on the adjoining building...down though the basement of another shop lined tunnel to another tall building with many floors of shopping. It seemed endless, and a place you could get lost in. I like exploring... the only place where shopping presented a navigational challenge.
