David,
as you know I've had the same unit since 2010. I have 'dirty' outlets next to the 'clean' outlets on the 10WQ grid. I always use the 'dirty' outlets for non signal path, non system gear such as lights. I have plugged three different RCM's into the 'clean' 10WQ power grid without issue.
up to now never had one issue that I know about.
