Re: M-Audio EX-66 studio monitor

It doesn't look as if this issue was resolved, but I have three EX66s myself (having bought the review samples), which have all become similarly flaky. I'm about to open up the worst offender, but my theory is that it's the switch which chooses between analog and the left/right channels of the digital input. I'm trying to imagine--without a schematic--where that switch would be (right after the ADC, before..?), but the wiper is certainly having trouble wiping..and I use only the digital input, so I could also just hard-wire two of them as "left"...
