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 ...

There are a lot of people that said their Darkvoice had build issues and static problems. Has Massdrops version avoided those issues?

I am very impressed with the detailed answers I've gotten to questions about products sold on Massdrop . In some ways this is how I wish Head Fi was . Thanks for taking the time to reply I'm now going to purchase this amp with confidence that even if there are issues they will be easily addressed by following what others have done previously. It's kind of a bonus that this is an older product that there really should be no surprises that have not been addressed already . Again thanks

Yeah the amp having some age and forum posts just about everywhere gives it the benefit that it'll probably not have some random hidden quirk no one has heard about. A secondary benefit is that the amp has a similar design to other amps, most closely resembling the "Crack" amp in build, albeit the Crack having more room to mod and fewer capacitors feeding the anode/power supply in it's base form, and a different preamp tube but with the same heater voltage design, which affects how they both sound when compared, and to an extent, the Woo WA6 (Non-SE), since while it uses a rectifier tube instead of diodes, and is transformer coupled (they fit 3 transformers, one in the box, two for output inside the chassis for impedance) there are certain design aspects that can be understood and even applied to the Darkvoice to make it better (Hum Fitz, LED Cathode Biasing, Heater Rail Dropping Resistors, etc) due to these amps being so similar and working on similar principles. I mean true you could always build a Crack tho, but if you want the tube sound now without having to build an amp yourself, the Darkvoice is a great option, and can work later on as a great start in amp building if you ever try to hammer out some of the kinks the amp has (basically what happened to me and I'll probably start working on my La Figaro 339 since my Darkvoice has been modded with everything I can think of and is dead quiet now).

Received my dark voice a few days ago and I am very pleased with the sound. I had initial hum in the right ear but pulling the power tube and letting it stay on for a few days resolved that. However, there is another tube issue that hasn't resolved that I am hoping someone can help me out with. Basically, I think the 6AS7 power tube is not making proper contact in its socket. It will play fine for a bit then suddenly the right ear will almost go silent while I hear very scratchy "ghost" versions of the sound coming out. If I tap the power tube it scratches the right ear very loudly and sometimes resolves and sometimes doesn't. I can usually get it into a happy balance by wiggling the tube and 'leaning' it to one side or the other. I inspected the tube pins and they look perfect. Is it possible this is just a bad tube or would symptoms like this be more indicative of a bad or badly connected socket inside the amp? This is my first tube amp so any help you might be able to offer would be very appreciated! Thanks.

FYI I picked up a Tung Sol 7236 and viola! The amp sounds perfect now. Thanks for the suggestion

Good tube! It's my favorite one even. I have a 7236 and 2399 from Tung sol and I like the 7236 better. I think you should look for a new driver tube as well. The Sylvania 6SN7GTA does a really good job. Look for one with 3 hole plates, short bottle and chrome dome. Like these: https://www.etsy.com/listing/694700204/matched-pair-sylvania-6sn7-6sn7gta-tubes You can find them cheaper than this but I just wanted to show you the picture to compare. Enjoy! Glad everything is working out for you!

Does the Darkvoice play well with 12 volt tubes?

What company makes Darkvoice headphone amplifiers? I tried googling it and I just find a boatload of reviews but no company website. I pose a question to you Droppers here and hopefully to the manufacturer. Any interest in a Darkvoice amp fully balanced XLR inputs and a four pin XLR output? Quoting Zeos, I'm a balanced f*g. That's the product I am waiting for. I hope it comes. Friendly comments welcome. Trolls please control yourselves. Peace.

Different topology and lacking point-to-point wiring of the Darkvoice. Then again, I have no idea how the XDUOO TA20 sounds. From the specs, the TA20 will certainly drive more cans (much lower output impedance than the Darkvoice), but the power output appears to be same from SE and XLR jacks at 32ohms. So, the only benefit from the XLR jack/connections appears to be elimination of ground loops from long cable runs.

You’re right. Cleaner sound is the « only » benefit. I use TA10 and I am very happy with the wide soundstage and warmth of the sound having rolled out the original tube with ejj82.

I received a tracking number on Thursday 6/13... and the parcel hasn't moved since. Last tracking update says USPS Awaiting Item. Has anyone's tracking shown actual pickup, or did Drop just print up labels so we'd think they shipped this on time?

After making a similar complaint on another drop, someone informed me that's what sometimes happens if they're using an international shipping partner. Still seems kinda useless to get a USPS tracking number in that case though... You may or may not see some updates from the other shipping partner under "tracking history" on the USPS site even before it says it's received by USPS, probably depends on the company.

When you track it on the USPS website it states sometimes who the shipping partner is. Try finding the tracking website of the international shipping partner, maybe you can get more information from them...

You get what you pay for bud. Dropping $100 on no name Chinese brand is far more likely to be a bad return then saving up for a well reviewed brand

This is a very interesting amp in terms of its power and the effect it has on the sound. The scientific measurements show that its best suited to high impedance headphones like the HD 6XX, otherwise noise and distortion levels set in.
