I have a headphone cable and a preamp connection have this problem, both using XLR connectors. The preamp connection can be fixed by rocking the connector, but the headphone cable... 50% on right channel at the beginning, when I turned the volume up, I heard distortion on right channel, then silence. So weird...
My non-STEM understanding of things is that it's all just a way to carry a signal from your source to the shaky wobbly bits of the transducer; if there's enough grime or a break in the cable the signal may then be attenuated or corrupted due to hindered transfer.
The very low volume to distortion to silence thing is a bit concerning since that's more or less what I experienced with the Cavalli Liquid Carbon before the one channel up and died. Have you tried reversing headphone cables to see whether it was upstream or not?
@Lyander I don't know... The thing about the attenuation on preamp sounds too consistent to me, it's mostly like a 50% volume off switch to me... But could be your theory.
Then the headphone cable, it should be Mrspeakers' official cable, so it should be fine? (Don't really want to open the cable blindly, at least the XLR end looks perfect to me) And I am using Liquid Platinum, so the distortion to silence thing could be Cavalli's protection design? Though the protection light didn't light up.
I once made a cable that ended up having severe channel imbalance. The culprint was a big solder blob on one channel on the 3.2mm conector (vs the other left cable which had a more even amount of solder). It ends up acting as a resistor and lowers the volume.
@señorhifi Well, that could definitely happen to me, as my soldering skill sucks... But my case should be faulty balanced connection, since at least my preamp used to work just fine.
