What's with BAT?


I’ve noticed that, over the last few years, BAT tube preamps have gone almost exclusively to the 6H30 tube. No more tube rolling like in the older preamps, such as my VK-3i. Any ideas as to why this has happened?

Thanks for your response. Maybe instead of "musical" I should have said expressive?
Your response included a lot of useful info. I've used Upscale Audio in the past.
Thank you.
rib61,

Apologies if I've taken your thread in another direction. Since the 6922s were mentioned here, I thought this may be of some interest.

rodman99999,

I purchased some tubes second hand through a member here who bought them through Andy's Vintage Tube Service. His site seems to offer more initial info and the prices are somewhat lower than Upscale Audio. The tubes I bought are very good, still in use in the unit I installed then in.
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.
