Headed to Shenzhen (the city) - what audio gear to get / where to go?

Hi-

I’m going to Shenzhen for a few days. I’m very interested in any recommendations that anyone has for specific stores / stalls to visit for audio - DAPs, DACs, maybe a headphone amp or pair of headphones. Interested in where to go, people to speak with, what items to look for and what not. Obviously need to be able to bring anything back in luggage so not going overboard.

I know this is the gear forum, but people here tend to know a lot and I’m eager to learn what audio gear you’d pick up, and where from!

Thanks,
John

Ok, looks like advice is generally to go in Hong Kong, where I will be after for a few days. I’m going to try to pick up the FiiO M21, which is relatively new, and get it at AudioSense, Let’s Go HiFi or somewhere in mombok. Shenzhen I’ll go to the audio floors of the electronics market but mostly just for fun.
