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...

Stock china valve. Absolute junk - does improve to garbage after about 2hrs. So warm it is unusable, mid & vocals aren't great either, sort of a nasty mucked up 50s radio.
NOS Brimar valve. Shockingly better - out of the box, and should get better over next 2hrs. Slightly warm, but not thick. Bass is deep, controlled. Vocals are airy, highs far better.
Adele's vocals on quieter tracks sound absolutely haunting. However this is an amp that does not like extremely complicated music, musical fidelity headphone DAC amp (HPA) was better in that respect - BUT could become tiring quite quickly.
There are 2 Gain jumpers. Stock is both set to HIGH not Low, so I may try setting them to Low at some point.
Might also nosey around the PSU caps as that is an easy. Not sure about this one, NOS Mullard/Brimar makes it auditionable, stock tube is a toilet.
Edit: I'm an idiot, all I had to do was open the thing up and it was pretty obvious. I measured the difference of both set to low vs both to high. At 2khz there's about a 5db difference between the two.
