The level of my left channel on my M50 began to drop and distort, then eventually died (but only with both outputs connected - they were ok individually).
I was able to re-solder the ground connection on the right channel to fix it. I had to leave the soldering iron on there for a few seconds extra to get a nice shiny weld. Looks like there was a last minute mod done one that connection with an extra wire added. That was probably enough to make it susceptible to a cold solder connection.

Yeah I have this problem too. I thought I had connected something up wrong.

I had similar problems with the stereo balance on my Radias, it turned out to be the volume knob which is a stereo analog controller that the audio passes straight through.

My m50 had hardware issue (left side output in headphones and audio outs was significantly higher). Just opened the back plate and wiggled one white connector with I think three wires in it. It's located just behind the outputs. I put a little multi purpose lubricant there, maybe the connector had just been oxidized. Works great. Very easy process Smile [/img]
