Probably the best value OTL Tube amp on the market. The Darkvoice 336SE punches far above it's price point, especially with upgraded tubes. You buy this Amp for a specific purpose, because you're looking to pair it with a high impedance headphone and you're desiring a slightly warmer sound signature. It's certainly not overly tubey or excessively warm however it does make absolute magic with brass, strings and vocals. If you're looking to buy this amp for EDM or lots of bass, you're probably going to be disappointed. Binaural FLAC files, especially of symphonic orchestras or vocalists are stunning. For the right genres the Darkvoice 336SE is phenomenal. I've personally used mine every single day for about four months now, 8 to 10 hours a day and have experienced zero issues. A must buy at the $200 price point if you enjoy brass, string, vocal or electric guitar focused music and have a high impedance pair of headphones to pair it with.
You don't need to break the bank upgrading tubes either. I've had fantastic results with an RCA 6AS7G and a 1950's Tung Sol 6SN7GT at about $30 for both tubes. A really unique and special sound paired with the HD6XX's. I'd challenge anyone to find a better value for under $500.
I second your opinion on the DV, 6xx and tubes.
I have a similar RCA 6AS7G and Tung Sol 6SN7GTB combo and it's excellent. The pairing provides a wide soundstage and good clarity, but has a little more high end treble than I like. Based on a recommendation from @pvrse I splurged and picked up a Shuguang Treasure for $100. The Treasure takes the edge off of the high end and adds nice texture and body to the low end. The soundstage is wide and clarity and separation are great. I think my tube rolling is complete for the foreseeable future.
I am looking to get a tung sol 6sn7 first before getting the treasure so I can try out more tubes. I am looking at the one here and they have a few different options:
I am thinking of adding the balanced triode and low noise option. I don't think I need the high gain as it is likely loud enough as is.
What do you think?
I have that Tung-Sol 6SN7GTB. I didn't get any of the options because I didn't know what they would do to the sound. As for high gain I rarely turn the DV volume past 9 O'Clock. I don't think high gain is needed. It was the first extra tube i purchased. These are my sound perceptions with the 6xx.
- It's provides marginal improvement in sound when paired with the stock 6AS7 power tube.
- With my RCA 6AS7G the combo is very bright. Not harsh, but the low end isn't as prominent. Good clarity and separation.
- I like this tube best with my Tung-Sol NOS 7236/6AS7 metal base. Together the imaging and detail are clear,but less bright to me and has a more balanced sound but still tubey and lush. I picked this tube up specifically to go with the Tung-Sol 6SN7GTB. This is an example where Russia and USA play well together.
My second tube purchase was the RCA 6AS7G. At this point I realized I could spend $100s looking for the right tube combo and decided to spend the cash and get the Treasure hoping to avoid that. It was the right call for me. The Treasure provides the lush sound I was looking for. Great low end. Kick and snare drum hit hard. Mids and highs are detailed with no harshness. The RCA 6AS7G and the Treasure are what spends the most time in my DV.
Great feedback guys. I've really wanted to try that Shuguang Treasure tube however the cost is pretty steep. I've heard many times that it's fantastic if you can afford it. I'll place it on my to-buy list!
For those of you looking for tubes, check out Ebay! Some really reasonable prices and good deals can be found there on vintage tubes. That's where I found both of my tubes for my review.
Hi, did you ever end up getting the treasure from Amazon? I was looking at that listing too and the price seems too good to be true so I was wondering if it was legitimate or not
Be aware that Shuguang sells their tubes based off of "quality". After assembly they are tested and given a grade. I remember awhile back looking at their 300B series for a different amp and seeing A-C quality ratings with respective prices. I've heard rumors it has to do with background noise levels or balance, however this is just speculation and unconfirmed. I would assume that's why this tube is approx ~$25 cheaper than some others. Perhaps it's simply a great deal however it might be a B or C grade tube. I'd keep in mind even a B or C grade Shuguang Treasure would be a really fantastic tube, surely much better than most others in the category. I've heard nothing but very, very positive reviews of the Shuguang Treasure tubes regardless of their final factory grading. Personally I'd be very happy to run that ~$70 Shuguang Treasure over almost anything else.
I haven't bought it yet because I want to try out tubes first before going for an "end game" tube. will definitely get it in the future.
do you know which website has the grade description? I'd like to post that question on Amazon to ask.
I saw this a few years back and it actually took me quite a while to pin down as they seemed to have either done away with the system, or it's simply reflected in the final price only. Psvane who is a trusted source of tube information had this to say about it back in 2011:
Interestingly enough this is different than the listings I saw on a reseller's website a few years back which did in fact have different 300B tubes at letter grades which he hints at in the article.
Here's an example of the letter grade usage AND the Export Grade / Standard Grade
Either way we have a bit of an enigma on our hands. That seller either has a fantastic price or there's something we're missing. Either way I'm sure it would be a heck of a good tube.
So from the sources it looks like the Amazon treasure tubes are the "so_so" quality described on that psvance source
Mine has smoke Q.Q
Going to listen to it for a few hour while using stock tube first. Hopefully it won't burn up.
A few wisps when you turn it on is normal from the assembly. If it's fine after an hour or so you're good. If you have any issues Massdrop will absolutely get you one that doesn't have issues. We're past the first day or so, how's it sound? I thought the stock tubes were pretty decent, better than most give them credit for.
The smoke issue went away after 2 hour or so. Made the room smell pretty bad. Stock tubes was pretty much dead silent after 2 hours and sounded pretty good. But then this is my first tube amp so I don't have any other references. Burning in the tung sol right now so I can't use it for ~72 hours :(
