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...

The AAA topology is still seemingly vague (though I'm not in the audio EE biz)....
How similar is the 789 to the following? (Yes, kind of apples to oranges, but....) Obviously swap out the Li-battery for the wall-wart. The 88 shows an earthed ⏚ analog ground -OR- should the circuit actually show a (floating) common signal ▽ ground point? https://www.triadsemi.com/product/tsthx88/ https://www.triadsemi.com/wp-content/uploads/dlm_uploads/2016/12/triadsemi_tsthx88_productbrief.2016-12-19.pdf
AND :) the THX patents have some interesting tidbits..... :) https://patents.google.com/patent/US8004355B2 https://patents.google.com/patent/US8421531B2
Thanks for the well-researched and thoughtful question. :)
As the product manager for this amplifier, I thought of the following criteria: -Vanishingly low distortion that AAA tech is known for -Usability from IEMs (low gain option) to more demanding headphones (2 more gain options with headroom for current-hungry planars & voltage-dependent dynamic drivers) -Very competitive pricing
There are many who believe in the most transparent upstream gear possible...purists in the amplification sense. The objective measurements are the key to proving the purity of the amplified signal.
After that- power, input/output flexibility, single-ended plus balanced output, and low cost are the most important factors for our headphone audiophile community. Providing the target specification (amount of power plus features above) to THX, our recipe called for 788 performance (world class low noise, low distortion, low cross-talk) and 788 cost, but 888 power. Took some design tweaks to the circuit and a helpful partner to bring this new amp to the community. So what do we call it then? 789.
