Black sable tube how good?

I’ve seen these tubes costing double of what some favorable Tubes are costing.
I was looking at the 6922 type.

Low Noise, Tight Bass, could use some more air. They sounded OK in minutes. Back ground was really black after I sorted out some tube rush issues. Gonna let them burn in see what they can do!!
