Sennheiser PC37X randomly goes bad after disconnecting the cable ?
Greetings, Yesterday I was using my headset like normal with my macbook, just listening to music and on a call with people like usual, and the headset was perfectly fine. The stock wire that came with the headset is extremely long and yesterday it annoyed me very much that it kept getting tangled with itself, so I decided to see if the cable is replaceable. I pulled out the cable from the headset and saw the adapter, and looked online for a replacement. Upon plugging it back in, the audio sounded extremely muffled and washed out. Im not sure what I did wrong to make it mess up like that as I've always taken good care of it, ive had it for about 2 years and its always just been chilling on my desk, but anywho I thought the cable just went bad and ordered a replacement. The replacement came, and the issue is still persistant, so I am not sure what the issue is I've tried multiple different headsets and the issue is not with the port, and I also tried it with my windows laptop and...

6080 tung sol NOS shanguang treasure for the 6ns7
That is where you can stop the tube rolling and call it there's nothing like it with the senheiser 600 series line. Trust me get those tubes and be amazed.
As for a dac I've tried high to low end, anything from the modi uber to the dragonfly cost area of a dac will suffice there's no need for anything costlier

That's where I acquired both, and I belive it's the best all around set up to date as a power tube and 6ns7 tube combo
Edit: I did burn-in by just listening to it, there's nothing wrong with the stock sound and you also can notice the small difference before & after burn-in on several tubes to judge by yourself. For me, it's a fundamental part of the tube rolling, I would never advise to let some gear burn-in without listening to it because it kills the experience.
BTW I'm also waiting for my DV to arrive, so hyped! Next month I'll buy some tubes, thanks @pvrse for the suggestion!
BTW i use a Rhino v1 DV (same thing)
Everyone listening experience is different however I prefer the stock tubes on this particular 336SE with total silence and no humming whatsoever.
I will try and play about with the tubes that I have purchased and mix it up a bit.
A bit of philosophy "if it isn't broken why fix it". But the mark of excellence has been set.
trusted and your final stop
The Tung-Sol 6SN7GTB has some serious hum. I am on day 3 of the burn in and it's starting to subside. I am following the instructions from http://blog.thetubestore.com/burning-in-6sn7-tubes-for-the-dark-voice-336se-headphone-amp/ Hopefully, the hum will completely disappear in another day or 2. I'll wait a while longer before passing judgement on the Tung-Sol 6sN7GTB.
I have listened to the Tung-Sol 6sN7GTB paired with the stock 6AS7 and the 6AS7G I purchased which is labeled as an Hewlett-Packard by RCA tube. At this point it seems that the HP/RCA 6AS7G tube is having the biggest impact on sound which I didn't think would be the case. I noticed an expanded soundstage, greater detail/separation and more mid-range and treble when I use the HP/RCA 6AS7G with either the stock 6SN7 or the Tung-Sol 6SN7GTB. The HP/RCA 6AS7G also seem to tighten up the low end and bass and snare drums seem to hit a little harder which I like.
I am hoping that some additional burn in time takes some of the edge off of the highs I'm getting from the HP/RCA 6AS7G. The highs on songs like Stevie Wonder - I Wish and RHCP - Give it Away are a little irritating to me when using the 6AS7G. I don't have this problem with the stock 6AS7 tube.
With regard to the DV336SE -> 6xx chain, I continue to be impressed. I used the 6xx with my Aune X1S the other day and think I finally understand "the veil". I have been using the X1S as a DAC for the DV336SE and decided to do a little A/B between the X1S Amp and the DV336SE. The 6xx sounded like something was being held back via the X1S Amp. When I switched the headphones to the DV336SE "the veil" lifted and the vocals and highs seemed much more clear and open. I had heard about "the veil", but never realized what it was until now. Fun stuff.
1. Are you playing music through the tube?
2. Are you putting various pitch frequencies through the tube?
3. Are you just leaving the tube on? I had the same experience hum on the right ear of my 6xx.
(Please note that the first two option is what I use for burning in headphones).
I am using the technique described in the following link to burn in the Tung-Sol. http://blog.thetubestore.com/burning-in-6sn7-tubes-for-the-dark-voice-336se-headphone-amp/
I have just left the the Amp on without the power tube (6AS7) in it. It seems to be working because the hum is much lower than it was initially. Today was the first day I could listen with the Tung-Sol tube in and not be distracted by the hum. The stock 6SN7 is nearly silent.
I shall try this.. 😊 😊
After burning the tung-sol the hum has subside tremendously, and in fact tolerable listening..
Thank you pvrse and mind head1.
You must listen to a track called "Night Mood" by Sylvester Harper with this tube set up and 6XX.. OMG...
Let me know your listening experience..
I bit the bullet and ordered the Shuguang Treasure. I should have it by Friday.
Also, found this post. Everything you ever wanted to know about the 6SN7 tubes.

The sound and imaging is something else. I cannot explain in words however its like 3d coming from the top of my head and then from behind. The highs is precise but not piercing where it becomes uncomfortable, and the middle and lows is present in but not overwhelming. The Sennheiser 6XX is not known for lows but boy this is the business.
Yes I am now a believer, a convertor. Absolutely top notch.
The volume doesn't even have to be any more than 8 o'clock. So I know this has power to go even higher.
I've only listened for a couple of hours, but so far I'm impressed.
Chain: Google Play Music -> Chromecast Audio -> DV336SE -> 6xx
just kidding but how amazing is this combo, all types of music thrives with the 6xx,660s,650
Can you please share your thoughts on how much of a difference the DV will be to the LD?
Btw, my headphones will be: SHP9500S, X2HR, DT770 (250 Ohm), HD6XX.
Thanks.
Second, the difference is very subjective: some people might prefer the more detailed & analytical sound of the LD, some other might enjoy the warmth & soundstage of the DV. Both have more than enought power to drive high impedance headphones like the DT770 or HD600/650/6XX, specially the DV: LD is meant to drive lower impedances, like planar magnetics, but is capable of driving higher impedances pretty good, while DV won't drive any low impedance headphones without sounding like crap.
Third, my comparison is not "fair", because I've rolled tubes & opamps on the LD until finding a good setup for both my HD6XX and HE-4XX (ask for suggestions if you wanna know, those sell really cheap and difference is 100% worth), while my DV has stock chinese crappy tubes (I wanted to buy better tubes, but couldn't afford it until a few days ago).
Now, from my experience, I prefer the DV for the HD6XX but not by a huge margin. It sounds more pleasant from the DV, indeed, and has way better bass (and a bit more sub-bass too). Soundstage is bigger too, and DV adds more "tube sound" (aka harmonic distortion) and warmth than LD. But on the other hand LD sounds more "accurate", has more clarity & detail and it's easier to tell minor sonic differences between records. I'd say LD is better for analytical listening, and DV better for relaxed listening. And since HD6XX are not too analytical per se, both bring something to the table: a bit more detail to compensate for the natural character of the headphones, or even more warmth and forgiveness for the ultimate relaxed listening experience.
It also depends a lot on the music you listen: for bassy genres like EDM, hip hop or anything like, DV is clearly the way to go, giving the HD6XX a much more impactful, beefy, textured bass (but controlled and non intrusive). On the other hand, for classical music LD might be more revealing and richer in detail, allowing you to hear nuances that DV will probably not.
I guess better tubes on DV will improve the sound even further: according to my readings there's a huge difference after upgrading tubes, way more than on hybrid amps like the LD I+, and you can also customize the sound according to your preferences by using different models.
To sum up, I'd say LD I+ stock vs DV stock is a unfair comparison: LD can be bought for <$100 while DV drops for ~$200. And LD with better tubes and opamp is still cheaper than stock DV (maybe you can spend ~$130-150 for the full package), and tubes for the DV are way more expensive too, so they play on different leagues. Is it worth the upgrade? It depends on a lot of things, it's hard to tell. What I can tell you, is that if you plan to drive several high impedance headphones and you enjoy the "tube sound", DV is probably the best price-performance "budget-ish" amp right now. But get your wallet ready, because stock tubes must be replaced in order to enjoy the "full experience", and replacements are not cheap: after a lot of searching on eBay, I found power + driver tube for ~$80 total, inc. shipping, because I'm splitting shipping costs with a friend; but those are not the best tubes you can find, by far.
I guess I'll have to go around listening to more tube amps for the "tube sound". I bought the LD I+ initially for the tube sound, then found that I could not hear much difference between the amp and from my computer directly. I guess I'm just too new to all this. Thank you though!
