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...

1) Is the input upsampled to a certain frequency before being sent to the resistor ladder? 2) Would a adding a 3rd party quality linear power supply add any improvement to the sound quality?

If this DAC I would contact the same AliExpress seller and see what they recommend.
1) We do use some integer-rate upsampling with linear phase FIR filters. This gives us a smoother output waveform and thus a smoother sound. Without the upsampling, we found that lower sample rates could have a harsher edge to the sound from the larger steps between samples.
2) The short answer is: yes! R-2R DACs, especially sign-magnitude versions, need precise, stable voltages for maximal performance. The RDAC has several power regulation circuits inside to stabilize the 5V DC we get from the supplied wall wart, such as the two precision linear series regulators next to the PLD on the top board. With these circuits, even the stock power supply gives good performance. With a better linear power supply, these regularization circuits don’t have to work as hard and the resulting voltages are even more precisely controlled, leading to more resolved sound.
Look what I found on AliExpress http://s.aliexpress.com/eyeE3Yfy
But it that is almost $300 shipped so you have to wonder is it better to just get a more expensive amp to begin with.
