Kevin, I've got a setup similar to Sycamore67's. I found a used Fein on C/L for a great price and I can tell you, it's very quiet. As Paul said though, it's the hissing/whistling/sucking noise right at the saw that is loud. I'm thinking of redoing mine in larger pvc with a wide mouth adaptor of some sort to see if I can make it quieter. Now that I have the EX, I am going to make something for it too. I left the long hose on the vac and run it to my saw across my small shop and when I'm using the EX it will probably be just outside the shop door and I can run the hose to it too. Anyway, the answer to your original question is, yes the high end vacs are quiet. Worth every penny in the long run. It just hurts at the time of purchase. Like anything worthwhile. When I was selling tools, my motto was "buy the best and cry only once". Makes sense.
