Product Description
Headphone amplifiers come in a variety of circuit designs, each with its own advantages and drawbacks, but there’s one main determining faction: distortion level. Credited with having the lowest possible distortion, Output Transformer-Less (OTL) headphone amps cut out a key part of conventional amplifier design to eliminate a major cause of audible distortion Read More

Hi guys, Recently I've replaced the 6SN7 tube for my DV336SE, which I am using as a preamp. Initially it worked fine and all of a sudden there's an annoying buzzing noise coming from the DV. It is noticeable even when the vol is at min. Also when gently tapping the device, my loudspeakers also picked up some noise like tapping a microphone. I've tried switching to another preamp and it's dead quiet, so it must be something to do with the DV. Any idea which part went wrong? Cheers.

It sounds like your preamp tube has gone bad and is microphonic. I’d replace it. If the replacement hums, you can try the burn in method (remove rear power tube and allow unit to run with just the preamp tube for 24-48 hours, the LED cathode mod (recommended), or a capacitor mod (fitz).

If the volume potentiometer (which connects to the volume knob) is 12 o'lock, the pins you should connect the positive terminals of the capacitors to, the pins are located at 4 o'clock and 8 o'clock. The silver thing in the photo is likely solder. Remember to discharge the caps before you dive into it. Usually, using the amp for more than twelve minutes (preferably longer), then turning it off, and leaving it off overnight should discharge the caps (mostly discharged when turning it off) fine. Still, check when your multimeter before really diving in. Off course, opening the amp up to do the Fitz mod will remove the anti-tampering stickers, thus voiding any warranty. Here's a close-up pic from mine before I did the mod (see the cap arrangement in yellow). Just follow the two resistors alongside the caps in your picture and those caps indicated below.

I got a newbie question guys: When using the DV can I just connect it to my Computer right away? Like without anything like a DAC? And if something like that is required, would a Dragonfly Red do the trick?

You don't need a DAC. You can connect from your computer's DAC (its audio out port) directly to the RCA-in of the Darkvoice usually with a 3.5mm male to RCA cable. Still a DAC is a worthwhile purchase for the future if you continue to try out more headphones and other gear, or if your computer output has noisy (e.g. hum, static, etc.).

Got my DV a couple days ago. Having a weird electrical hum/buzz when connected to my thunderbolt audio interface (Zoom Tac-8) or directly to my laptop. However, when I use my iPhone as the source, there is no hum. Could this be an issue related to grounding? I have both my interface, computer, and the Darkvoice connected to a Furman power conditioner.

Does anyone know how this compares to the Schiit Velhalla 2? Or even the Mjolnir 2 even though it costs much more?

Highly recommend de-soldering the ground from the RCA outputs. Huge difference. It's no longer so dark and overall sounds much better. also here’s the LED mod.

I replaced the bottom eight screws- (M3-0.5 x 8mm), be sure to check for clearance. There are two wires you may have to wiggle out of place of the screw. A 3mm screw length is closer to stock ones.

Update: Swapped out the bright orange LEDs on the 6sn7 socket to something more ideal. A dim red led (630-HLMP-6000). Huge difference, I should not have used the first set.

Here is the pre-amp output removal by desoldering the black ground wire located in the top right of the pcb. Next to the R.

Update: Stock feet are easily removable. 3mm screw. Replaced with adhesive silicone hemispheres.

update: new solid aluminum volume knob. Stock is plastic with a metal sleeve. New potentiometer soon..

You can desolder the two preamp our wires. Or even snip them if you want.

Hey guys, recently got a 336SE off a mate and was wondering if the 6SN7 is the culprit of a low left side output and muddy bass from the same channel of my HD6XX? I've eliminated the jack/cables/port as the issue. Just don't want to buy a good tube (Looking @ Tung-Sol 6SN7). Help? :D

The Tung-Sol is like twenty bucks and the Black Treasure was maybe fifty on eBay. I didn't exactly break the bank.

I was referring to the Black Treasure. I thought it was one of those $90 tubes. I have a few NOS Tung Sols. I actually prefer some of the RCA preamp tubes. The Tung Sol 5998 7236 is a nice tube. I just checked my records and spent $290 and have 18 tubes. 5 power tubes and the rest preamps. The only tubes that aren't dead quiet was a Raytheon VT- 231 that's usable with louder music styles but I have 2 of them and a Sylvania that didn't improve at all and is too noisy. It seems the more rugged militarized tubes can be hit or miss due to the higher manufacturing tolerances which logically sounds counterintuitive. I played, I experimented, I'm done with tubes. Especially after spending $350 on tubes for the Little Dot Mk II.
