One of today's best renowned master of the instrument is
Xu Ke, who has released a bunch of recordings for RCA Japan. I doubt these are easily available in the West.
Probably easier to found is the young player Chen Jun, with several recordings under the Marco Polo label, one of which re-released under
Naxos World
The Hong Kong based label Hugo Music was a great source of Chinese Traditional instrumentals. Once upon a time they were carried under Harmonia Mundi, but I don't think it is the case nowadays.
