SL3 Distortion low Volume In One Speaker

[HG5150]

I have a pair of SL3s and noticed that one (AKA right channel) is less powerful than the right channel and distorted. I replaced the IC chip and still the same issue. I did the usual tests as in swapping cables, switch each speaker to the opposite channel, changed amps, etc. Still the right channel is distorted and slightly lower in loudness. Any thoughts?

Have you done a very thorough cleaning of the panel? Unplug overnight then vacuum with the brush attachment.

Sure did. I spoke with ML and they suggested the IC swap which is done, then to do a RMA to check the power supply. Just wondering if anyone else has had this issue.

Update-
I did swap the IC, however, that did not solve the issue. I sent the board in to ML and it was the Dynamic Expansion Circuit which only cost me 75.00 including shipping. The SL3 is now sounding great!
