Okay, so every audiophile or audio enthusiast I’ve met wants one of these and there is certainly a reason for it. Besides the fact that this thing just sounds incredible…..
for many people, it is important and fun to change the signature of what they are hearing. BUT to do that we end up spending a lot on different types of headphones. BUT with these tube amp, something called “tube rolling” makes changing sound signature possible. Which is physically buying a new tube and changing it (not hard… its basically push and play). Call me crazy but tubes cost a lot less than headphones!


okay, many of you probably stopped at the “ability to change sound signature” and is ready to buy it. That is totally fine because that itself is enough for people to buy this. BUT do check out the “concern” section to see where you should buy it to avoid all those concerns. Anyhow, the link to best seller with a lot of sale, promotions, FAST shipping (got mine in 5 days) & most important of all no need for concerns noted below because units are all tested. https://https://www.aliexpress.com/store/product/DarkVoice-336SE-Headphone-Tube-Amplifier-neat-technics-headphone-amp/601461_630928527.html/

ALSO contact them on their sales and they are flexible with prices and will help you get the best market price ! But forget the price… their units are at least flawless… from package to everything.



I get this question a lot. Andddddd the answer in my opinion is HD600s & HD650s. BUT any high ohm headphone should be great with these. so I think its time to bring up the first concern. CONCERN #1: these are for high ohm headphones… BECAUSE of the way they are built. These are a 100% tube amp. This restriction is why hybrids were made perhaps.


it is sturdy and made of metal/aluminum and that makes sense because these things get hot. But you have to realize… some people have misconceptions… they won’t turn your room into a sauna or melt everything around it. Just don’t touch it and you are fine.
The blue LED light gets annoying sometimes but… atleast it tells you that its ON, some amps don’t bother. Now the CONCERN #2: search darkvoice 336se smoke on youtube and you get plenty because sometimes they do smoke up. This is why you want to buy a GOOD unit from the RIGHT place… so that you don’t get that dysfunctional one on youtube. note to yourself: buy from the seller I recommended, it will save you the trouble.


Quarter inch jack headphone plug in in the FRONT
RCA input and output in the back
THE Power cord is sent compatible to your area, at least from the seller I got mine from.



Important yet vague question in this case. WHY? because you can change that but let me tell you the sound with stock tubes (which are not the best tubes you can get).
The base is definitely extended on my HD650s. Everything feels grand and relaxing. Vocals sound clear and perfect whether they are singing quietly or loudly, every details is there. Mids are great as usual on the HD650s with little improvement but that could be me convincing myself. The highs are more detailed but does not in any way hurt me ears. (if you know what I mean)


the question I get the most. The correct answer would be “its your preference.” My answer would be General Electric Tubes (watch z reviews tube rolling video). I used them and am very happy with how it sounds. (it sound clearer and deeper in all frequencies)


Tube Used : 6N8P, 6N5P
Frequency: +/-1dB 10Hz~20kHz
Distortion: <=2% Output impedance: 32 to 600 ohm
Power handling capacity: 1W
Output terminal: 6.3mm Stereo Jack
Input terminal: RCA Jack
Power supply:  110V, 220~240V version (Note:110V will delay 3-5 days delivery)
Case dimension: 290(L) *160(W) *135(D) mm
Gross weight: : 5.5kg



Thanks for reading my review fully. SO in conclusion this amp is incredible in sound and flexibility but have few concerns that can be simply fixed by buying a tested unit from the buyer I recommended. Also I told them I would recommend them on my review because of their great service, so Mention that you were recommended by SOULSIK and they should give you the best price possible. Thanks again ! and check out my Instagram for more photos of the products I review ! https://www.instagram.com/soulsikreviews/

    How does this amp compares tout something like a Little dot mk4 ?


    1. the biggest difference would be the tube rolling possibilities on the darkvoice. if you need to pick one or the other, I would suggest the darkvoice as there are more possibilities to satisfy yourself in the future

    Just got this amp. With HD650 it’s sounding quite good, the tubes aren’t warmed up enough yet so I will reserve my final judgement till then, but so far so good!

    Regarding tube rolling, you can get good advices on HeadFi forums. Find someone who likes “sound” similar to what you enjoy, owns similar HeadPhones than what you’re using and you will have a choice of tubes to try first. It will probably help you avoid spending money on tubes you are not going to like anyway. Do not forget that with some amps you can also use tube-adapter to have more options when choosing rolling tubes.

    I’ve owned my dark voice for several months now it’s my first headphone amplifier and it’s my first tube amplifier. Got it on Massdrop $199. I was gifted nearly 100 old new stock tubes brand-new in the boxes of different years and manufactures most of them were 6SN7 ,6AS7 and 6080 I did not know what to do with them so I googled vacuum tubes and research the numbers and stumbled upon Headfi.org after doing some research and many midnight sessions reading four hours what tube amp would pair with the tubes I have just acquired I decided on the dark voice and never regretted it. Also in my research the HD 650s was the most recommended headphones so I just purchased my very first high-end headphones ( Sennheiser HD650) to pair with my new amp and my new tubes. It makes the music coming out of your smart phone or computer come to life like you’ve never heard it before. It’s beautiful the way tube rolling can enhance the sound of your music to what pleases your ears . Now I just need to make my first purchase of my first DAC.

    What is the model number for the general electric tubes?

      I have found a perfect addition to add to the DarkVoice 336se. When your source is a computer or a phone add a DAC to clean up your audio source from the poor performance of the low-quality DAC provided in your computer or mobile phone. I just purchased the ( IFI Black Label , DAC AMP with BASS boost ) which really helps my Sennhaiser HD 800 , I also have HD 650. The IFI Black Label can be ran as a preamp with no power directly into your Dark Voice. With the HD 800 there so precise at detailed audio they will pick up any bad recording’s any background his or compressed files that do not sound good and amplify the problem. So you must have clean recording’s like Flak or Lossless etc. to take full advantage of such high end headphones and clean source files. The difference is night and day to your ears.
