Youku Video: 'Flowing Waters' played on guqin mounted with silk strings

Chanced upon this Youku video, played by a maestro on guqin mounted with silk strings. Perhaps the echoing reverb was added in audio post production, but still it sounds very nice. hahaha

Videos of guqin pieces performed on silk strings are still quite rare. The majority of videos on the internet primarily feature guqin performances on metal-nylon strings. Nothing wrong with metal-nylon strings though, but I still prefer to use silk strings, because there are no metallic sounds in silk strings and (please correct me if I am wrong?) they may be more eco-friendly. (*smile*)
