    Is yours a 6sN7GT or "GTB"

    I too have found that same set up to be rather satisfying along with about a dozen other combinations . Using the IFI Black Label to clean up the signal out of my laptop to the dark voice was a great step forward . Also using my dark voice as a preamp to my Nelson Pass, First Watt , Amp Camp Amp class A amplifier kit to drive the Foster BK-20 speaker package. It always amazes me when somebody commented that they could not hear the difference swapping out tubes from the originals to a good pair of new old stock . Just as there are people that are colorblind unfortunately some people are also Tone deaf. B154279B-860A-40E1-A7E7-57B0118E0FE8.jpeg

    Rolling tubes - are they equal, power and driver? Or would most of the change come from swapping the driver?
    I have one power tube and two drivers on the way from ebay. Can't remember which, but just to try different ones.

    Yes, Mine is GTB

    Damn mine came in with the power switch broken off. looks like a few others have had the same problem.
  6. ohsigmachi
    That Sucks!

    Did you order through Massdrop?
  7. Th3Drizzl3
    yup. im waiting to hear back from them now

    Is anyone using the 336SE on a step down or step up transformer?

    On the back of the unit it shows it supports 50 and 60 Hz, so voltage conversion should be good enough

    Hearing can be subjective as you pointed out, but in this case, here in China the included tubes cost a grand total of 7.25 US! For both! The Dark Voice didn't sound bad when I first got it, however once my RCA and Silvertone tubes showed up, WHOA!!!! My Fostex TH-X00 and AKG 712's truly shined, as did the clarity of the Nano Black. So count me in on the tube upgrades, it's a no brainer!

    Just curious if anybody has tried a Mullard 6080 and KenRad VT-231 Black Glass pairing in the DarkVoice?

    Something is wrong with my DV. Stock power tube puts out quite a show
  12. ohsigmachi
    Yeah' that is BAD!
  13. dobigstuff
    Did you try a different Power Tube?
  14. maheeinfy
    Yes. It works fine with a RCA 6AS7G although there is the dreaded hum. I am hoping it will go away after burn in
  15. Necron99

    In my experience, it's the driver tube that causes hum, not the power one. Have you been able to swap driver tubes with the same RCA 6AS7G?
