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.

Definitely worth the money, IMO. I think they used 12Ax7s or 12AT7s. No experience with the 6922s. My CD player uses them and I replaced the stock tubes with some vintage Amperex from Vintage Tube Services. I think I paid about 180 for the pair, but well worth it.
