What's with BAT?

Recently purchase a new BAT VK 33 and do have 6922.
I bought this unit because it does not carry the super tube 6H30 DR.
Allows me to try a large slew of 6922/6dj8.
In my system the Pope PCC88 sounds the best followed by the Amperex 6dj8.

I'm not going to relay the manufacturer of phono stage I'm listening to out of respect for the designer....

From my conversations with him, he states most haven't used the 6922 in a way that achieves best performance.

So, no matter what, there will be many theories.

Boy I am not a fan of the 6H30. Just has a small sound. It does fit into closed cabinets, ones with lids on them, not sure that is of much concern to serious listeners. To me small tubes have a small sound. 845's to me have bigger sound then EL34's for example. Can you think of other examples.

I'm a big fan of the 6SN7, especially in the Cary SLP-05 preamp, as well as the 12AU7 in the VTL 7.5III which in my opinion occupies rarified air in the tube preamp world.

I've heard a few BAT's but never was really that impressed.  Different strokes I suppose...
