Well I went out and shot a video today, and it is not making as much noise when switching as it was yesterday, the loudest time today was switching from high to low, yesterday it was louder starting or switching from low to high. I will try to upload the video to youtube and post a link here shortly. Please ignore the pump loosing prime on high, the water was still a little low in the skimmer from the DE change yesterday and I was bypassing the solar heat when manually switching to high today which allowed for just enough extra flow to let the skimmer suck air. I was going to redo the video after adding water to the pool, but did not find a quiet time in the mechanical room to do it, the well pump and the water pressurizing pump are both in that same room, water was being used around the house (laundry, etc.) so the pressurizing pump (variable speed pump) was revving up and down, etc.

p.s. after reviewing the video the sound does not come through much I will try to re-shoot the video tomorrow and try to capture the sound better it is getting lost in the background noise on the current video
p.p.s. since everyone seems to suspect the capacitor I will try to test it and report back also
