6sn7 to 6922 adapter: good idea or bad idea?

I was messing around on tubedepots website, and when I put in 6sn7 as a serach enginge, these adapters came up to put into a 6922 socket so the 6SN7 could be used.

I would be using a pair of them in front of a Cary v12 (Cary calls them the "driver + input" tubes). There is plent of room on the amp  where those tubes would be going.  I have several pairs of tested good vintage 6SN7s I could roll in those sockets, and that's why the adapters caught my interest.

I used Garage 1217 6922 and 6sn7 adapters with great results in a couple MHDT dac’s. 
 

The 6sn7 and 6922 tube replaced the 5670 tube and sounded very nice in comparison. I had a large stash of very nice 6922 and 6sn7’s and was told by manufacture it was okay to run them so why not, but they were only tube buffers. 
 

Not sure I would feel comfortable in a preamp  unless amp manufacture could guarantee with no issue, even then would be a little skeptical. 
 

I found the Garage 1217 adapters to be very high quality ceramic sockets and gold plated pins.

I thought the sonics were as good and often better than the 6922s

@armstrod I've often felt that the 6922 is not a good tube for audio and also think the 6SN7 to be better. But the 6SN7 has different operating characteristics so its highly unlikely that the 6SN7 in your situation is actually strutting its stuff. A change in the cathode resistor value is likely to unlock that.

OP

I like the sound of my Cayin’s 6SN7 and 6SL7, however,

6SL7: I tried one new pair (6SL7WGT Sylvania brownbase), hated them, tried another (GE 6SL7GT, side getter, cylindrical plates), sounded terrific just like the super sounding Cayin branded originals.

do you have a few recommended versions of 6sn7’s?
