I was in Portland last summer, but most of the stores were still closed or only accepting appointments. A friend of mine just bought a pair of Wilson Sasha's and is selling his Maggie 3.7i's. I'm picking those up in CA next weekend and get to try them out for five weeks while he's in Holland. I can't wait to hear them in my home. I have a set of AntiCable Autoformers, which should help the PrimaLuna drive them. I'm also adding an active crossover from Sublime to pull the lows into the subs before the PrimaLuna, which will also help it drive the Maggie's.
I love the subs. It took me a long time to get them dialed in--I kept tweaking them until they now sound great. I also turned down the 25 Hz knob so they don't compete with the subs until I get the crossover.
If you're thinking about buying REL, I suggest you contact Albert at Precision Audio and Video. he made me a great deal on the two s/810's I purchased.
I'll update this after playing with the Maggie's for a few weeks.
