Warm sounding 6922 Type Tubes

@tomcy6 I bought the Mullard from Brent Jesse from his recommendation. I called him earlier today and still thought the Mullard was my best bet. He also suggested the Amperex but there was no guarantee it would sound better. He did hear from some people that tube dampers might soften the top end a bit. I have some so I experiment tonight. Thanks for your responses. 

Are the Mullards fully broken in? Tubes can be quite harsh sometimes in the beginning. 

I prefer using the clearest and most transparent tubes rather than dulling things down due to harsh sources. Fix the DAC. Cca run about $400 a pair.

I've never heard of a 6922 that folks called warm. Their claim to fame is clarity and details iirc. There are adapters to allow for the use of different tube types, maybe that'll be an answer for you 

@gregdude has an idea. There is a tube seller named Tubemonger. They sell socket savers and adapters. One of the adapters allows you to plug a 12XX7 tube into a 6922 socket. Here’s the link:

Before you try a tube adapter, I’d talk to someone knowledgeable about your DAC and Brent Jessee as well as the people at Tubemonger to make sure it’s a good idea for your DAC.

The link says it adapts to an ECC88, which is what the Europeans call a 6DJ8.
