I"m a Vandersteen guy and would always tell folks to put them on your short list. There is a reason that Vandersteen has been so successful, even while not advertising as much as Wilson, B&W and others.
They are your ears in your room. Glad you got those two in to listen. It just shows you that system matching is key. So many on the boards just purchase what folks tell them etc... and never match components. The Audio Physic's line is all over the place for my ear. Every time I've heard the different models in various stores, they all sound different. It has a house sound, but not as much as many others have. There are a lot of companies like that. Elac is like that. Often times it's dues to using different designers.
I'm not sure what's going on with Revel. A friend has had the line since their inception, but he hasn't sold a pair in a couple of years. He has their newest speaker and hasn't been able to move it and doesn't know what's up with the company. I have always enjoyed them when driven with higher end gear. I'm sure you will make the right decision as long as you keep bringing them in to audition.
If I was in your situation, I'd try to get a pair of used Vandersteen Treo's or even Model 5's as well as getting a pair of 3's new. I love the 3's as they play loudly, but also with plenty of finesse. They won't be as resolving as Treo's on up, but are a great value in their price range and why they have been such a great seller for 30 or so year (as they keep getting upgraded, meaning their original design was that good that you can just keep upgrading all components and getting better and better sound).
Few others can make that statement at this price point. You are doing the right thing in getting speakers into your room. Wish you luck. There are a few that I'm sure you will love with your Clayton amp that you love.
