I own the single tube version of the Yaqin and was one of the early advocates of the JAN6922 and it does work quite well. That said I have moved on to the Russian 6N1P with even better results. Cleaner mids, tighter bass and equal highs.
Incidentally the tube socket on my Yaqin is labeled with numerous tubes that can be used and the 6N1, 6922, and 6DJ8 are all included. Currently my buffer is in use between a Cayin MT12A amp and Denon multi format DVD/CD player to remove/smooth some of the harshness from the output and does so quite well.
