Glory,
You might ask douglikesaudio, who also has an all Audio Note system and a 2.1 Sig DAC. He's tried a few 6922's, I believe. I've tried the Mullards in several applications, and for around $90/pr, I find them sound great. Not overly detailed, not overly lush. In our 300B integrated amp, they were the only tubes aside from the crazy expensive Siemens CCa's that I found to be musically satisfying.
Best of luck,
Howard
