Is there a worthy 6922 presently made?

Why hasn't any tube manfacturer designed a good sounding 6922 tube? The paucity of decent designs only fuels the exorbitant price gouging the tube dealers are doing with NOS 6922/6DJ8.

I think it is pretty universally accepted among tube fans that the Sovtek 6922 is a dependable & strong tube, but a sterile, thin, & dead sounding device. Some have praised the JJ 6922, while others have proclaimed it rather mediocre, and some have blown up their amplifiers, like an ARC owner who burned out parts of his VT-100's circuit board when attempting to substitute the JJ's for the stock Sovteks in the input stage.

Sovtek's owner, New Sensor, has come out with a "new" 6922 in the form of an Electroharmonix 6922, with claims it is significantly better than the Sovtek. But some have said it is nearly the identical tube and sounds nearly identical. Audio Research claims it is a better tube, but.....

Why hasn't Svetlana designed a 6922? Or someone else? We are left with two tubes made by the same manufacturer, and one from Czechoslovakia. That's it! Any thoughts or experiences?
