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

I have had this amp for 5 years. I don’t use it as often as I used to but every time I fire it up with the 6xx I’m reminded why this amp sent me scurrying down the audio rabbit hole. A true classic.

please help 😔 I’ve had the darkvoice for about 6 months and i absolutely love it with my Beyer’s and my Senny’s /s and a month ago out of nowhere it started producing a low humming noise constantly through the headphones. I can hear it when music is off or during quiet parts of songs. the tubes are definitely burned in btw. I’m not very familiar with the tech behind tube amps so I really would appreciate any help :-( it was pretty expensive and i feel like i just got it :-(
Troubleshooting i’ve tried so far:
I’ve disconnected everything and tried a different wall output, humming still there.
I swapped out the tubes for the stock tubes, which were fine before, and still there’s humming.
i’ve moved it away from my other electronics, turned everything else off that could be causing interference and still there’s humming
I heard that cleaning the tubes can help with unwanted noise, but all of the tubes i have are only a few months old, how often should one clean their tubes? and how?
any help or recommendations for other things i should try would be greatly appreciated thank you!

k0nverseIt’s the amp itself unfortunately. It’s been tested to deliver distortion/noise ratios from 5-20% depending on the load…this is not good.

k0nverseThis reply is probably too late, but the humming you hear is coming from the heaters (the glowing in the tube) , The wires that come from the transformer should be twisted together, but in this amp they are just straight wires. Twisting the wires results in self cancelling of the humming.

I purchased this amp and I'm waiting on this amp to be delivered. I'm very new to tube amps and I'd like to ask what other tubes will make this amp sound as best as possible. I'd like to make it sound good, and "tubey" so that I can easily tell the difference on what this does differently from a solid state amp.

Why would the following have such a phenomenal difference using the DV 336SE? Please see below:
My signal chain is as follows:
Qobuz/Tidal
iMac 2021 USB -C
Audioquest USB Cable
ifi iPurifier3
SMSL SU-9 (DAC/Pre)
Audioquest RCA
DV 336SE
AudioQuest RCA
SMSL SH-9 THX AAA Linear Amp
Audioquest Custom 6.35mm Stereo to Dual Mono 6.35mm
UA Volt 276
Speakons
Mackie BST 15's Powered
Mackie DSM 18 Sub
This sounded so awesome and can easily remove drywall nails at volume (actually true)!
I, one day, mistakenly plugged my output cable from the SMSL Amp inadvertently directly to the DV 336SE Headphone out, bypassing the SMSL Amp. The sound was even warmer and much more intense coming straight out of the DV headphone jack. I moved my BD DT 1990's to the Headphone jack out of the UA Volt 276 and discovered something phenomenal... Listening to an audiophile class open back headphones with percussive musical impact around you IS the missing concert experience with headphones!
My question was: Why would that move make SUCH a difference? I get the whole line level conversation, but the signal coming off the DV 336SE headphone jack has 30-40% more current coming off of it compared to the RCAs.

Bass-HeadPerhaps higher impedance (resistance) from he jack causing the tubes to work harder? Guessing though.
