I will be installing my mp40 QD driver this weekend, including before and after tests with a decibel meter. Stay tuned for the results.

I got an MP40wQD to replace an MP10 I was using on the left side of my tank. So far, it's a world of difference flow and noise-wise compared to the MP40wES on the right side. I can barely hear the QD even at 70% while the ES has a very audible whine at that level.
It was so big of a difference that I got a QD driver for the ES. It makes the ES just a little bit louder than the QD, which means it's still ultra-quiet. Worth the price if you have an ES and are looking to upgrade for sure.

I ordered a MP40 QD driver for a noisy MP40 that I had... I didn't expect a miracle but was hoping it would be at least a bit quieter. Before I could hear it a couple rooms away and couldn't put it on pulse or wave mode at all as I could hear the whine of it winding up and down right across the house.
With the new driver it is virtually silent. I am super impressed. I can't hear it at all. If I put my ear against it I can barely hear it. I don't understand how just changing the driver can make such a huge difference. It's still the same motor... but I'm happy about it.
