Over 10,000 products; seven floors of audio; "every manufacturer who matters from the US, Canada, Europe, China, Korea, Japan, and Kowloon;" and more than 30,000 people over four days.

We went to the "audio district" of GuangZhou—in China, all shops of similar character tend to group together, so the audio district is where all the hi-fi shops are. Actually, they're there twice: many store have display showrooms in the central mall and listening rooms ranked along a nearby alley.

"Tannoy is updating its line without abandoning its strengths," the suave Tannoy rep explained to me. "Listen to this recording of Salvatore Accardo. It's an old analog recording and it may be a tad too warm, but you could listen to it for hours."

Du calls this conference room, "the battleground, because we argue about designs all the time. It gets pretty heated."

All the way across town from the audio market is the area where used equipment and parts are sold. Many small shops are specialists, such as this transformer kiosk. Not only can you buy thousands of transformers, but you can pick up plates and wire and roll your own.

Some tools are universal.
