Audio-gd products are very popular here on head-fi; I noticed Kingwa also designed a low jitter clock that's much less expensive than those from Audiocom, Tentlabs, LC Audio, Dexa, Burson etc, so I got two from him last year. Turns out that for some unfortunate reasons, my player just doesn't allow a new clock to be installed. I ended up buying an external reclocker. The modules look very well made and have been sitting in storage for months. I think it's time for them to go.
I have both the 33MHz version and the 27MHz version, and because they come with frequency dividers, you can do 16MHz, 11Mhz etc, so practically it covers everything. You can see the picture here:
Installation is straightforward (as long as you have room and your digital source allows clock mods), so I can answer the basic questions. You can also contact audio-gd for more information.
