I forgot to mention. To owners of the Romulus or Pandora dac, tube rolling also yields nice results. I replaced the stock tubes with some nice NOS types with great results. Sylvania Gold Label and some EI NOS tubes. More air and illuminated top end were the biggest gains.
I decided on the 5751 12ax7 varient with the Sylanvia Gold label. Slightly lower gain, but that is a good thing for my system.
