These are the tubes that Upscale Audio recommended to me. I was surprised how this little DAC came alive after they had time to break in. A substantial upgrade over the stock tubes...

The stock Chinese tubes were a little faster, the Teslas richer. I also tried GE 5751s and was not impressed -- to slow, too golden sounding. I found myself longing for the fast Chinese tubes.
