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...

Note: I'm new to this.
- Little Dot MKII is a OTL amp, and it's a perfect match for high impedance cans like the HD6XX. I have the Little Dot I+, a hybrid version of this amp, and it works pretty well. The MKII is supposed to be even better for this kind of headphones, so it's definitely worth.
- Stock 6J1 tubes are crap, you HAVE to buy something better to replace them. Using the stock chinese 6J1 tubes would be like mounting economy tires on a Ferrari: ruining the whole thing for saving a few bucks. For $20, the GE JAN 5654 are a solid upgrade. And you can always buy some other tubes later to test and compare, just make sure to look for "matched pairs". My two favourite tubes are the Mullard M8161/CV4015 and Voskhod 6ZH1P, both great for the HD6XX, and both can be easily found on eBay for a low price ($10-$30). Some more info about tubes can be found here: https://www.head-fi.org/threads/little-dot-tube-amps-vacuum-tube-rolling-guide.563884/
Also, im also thinking of getting a decent turntable which i hopefully i can make use of this amp too. That of course i can't use the dragonfly red. :D Please let me know if you have more two cents on turntables, and rolling tube amps. :D Would love to read/hear opinions. Thanks so much btw!
About tubes, I've heard just four models: - Mullard M8161: zero background noise, a tad bright (in a good way), crystal clear, spacious and airy, amazing for female vocals. - Voskhod 6ZH1P: noisy until well burned-in (about 50h or so), neutral (not cold, not bright), super balanced, great midrange. - Valvo 6CQ6: a bit noisy, lacks some bass for my taste, mid-centric and intimate. - Chinese 6J1: crappy, noisy, looks fragile and poorly built, too bright, lacks body and definition, harsh, get rid of them ASAP.
Price/performance, and according to your preferences, the Voskhods are the best: you can find a matched pair for around $15 with shipping on eBay, and you'll love their sound, one of the best sounding EF95 tubes according to a lot of people (also me). Mullards M8161 are also great, I prefer them for my Fostex T-X0 planar headphones (T50RP mkII slightly modded) and, depending on the music, also for my HD6XX; but M8161 are a bit pricier and harder to find, I could buy my pair for around $30 a few months ago but couldn't find any matched pair for this price ATM.
And another important thing: the power tubes! There's a lot of soviet 6N6P tubes on eBay for ~$20 with shipping, and I read that they can improve the sound a bit. It's probably worth buying one pair and trying for yourself, worst case you got some spare tubes that you'll need at some point (you know, tubes don't last forever, they usually work for a few thousand hours and eventually they blow out).
