Guys - I am trying to troubleshoot bass distortion with my Abyss and it's driving me mad. Mostly because it's intermittent and minor and been going on about 3 weeks. Essentially I hear a "ch" on the attack of bass notes in the left driver.
I most easily was able to isolate it with this simple acoustic bass test:
It happens like once a week, so it's very hard to figure out what the hell is going on. I've been in contact with Abyss and they told me to flip cables. Well, I have dual XLR Super Conductor cables and I did - and then I noticed the distortion move from the left driver to the right driver. This was the one and only time I heard it in the right driver. So I sent the cable to Abyss to have a look about a week ago.
In the past week I've been listening to the stock cable, and no distortion ... until last night. I heard it again in the left driver and went back to my test track and confirmed. Then I swapped cables, but it stayed in the left driver. So turns out my SC cable is fine.
This occurs with multiple amps and the Abyss but does not occur with other headphones. I initially thought it might be a hair or something stuck in the driver, so I gently blew on the driver and it went away. But then it came back a few days later. And then it goes away in a couple minutes.
It's gotta be the drivers, right? Or at least the headphones and the internal connections? It's driving me absolutely batty.
Anyone experience anything like this before? Any help is appreciated.
