Try to get a NOS Tung-Sol USA 6SN7. You may never go back to that 6922.
Here is my setup:

Is yours a 6sN7GT or "GTB"

Using the iFi Nano Black as a source to the Dark Voice. Using a RCA 6080 for power and a Silvertone 6SN7GTB to drive. Wow, compared to the included tubes is night and day!

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.

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.

That Sucks!

Did you order through Massdrop?

 

[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?

 

[maheeinfy]

Something is wrong with my DV. Stock power tube puts out quite a show

Yeah' that is BAD!

 

[dobigstuff]

Did you try a different Power Tube?

 

[maheeinfy]

Did you try a different Power Tube?

Yes. It works fine with a RCA 6AS7G although there is the dreaded hum. I am hoping it will go away after burn in

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?
