Hi,
I've had a pair of the Wind River GSs for a little over 2 years and I love them. They have an outstanding soundstage both side-to-side and front-to-back, they image very well, they absolutely disappear, they have great bass and are a pleasure to look at. Prior to buying them I auditioned Montanas, Coincidents, Osborns, B&W, Magnepans and Merlins (with the BAM.) None moved me the way the Reimers did. Over the last two years I've listened to a number of single drivers and horns (mostly at the recent VSAC in Washington state) and while I was impressed with Edgarhorn, Rethm and Cain&Cain, nothing has inspired me to move from the Wind Rivers. In fact, as I have upgraded my electronics over the past two years, I like the speakers more and more.
As mentioned above, Rick Reimer has had very little exposure yet produces an excellent product. I wish more people could hear them. Plus, Rick is a wonderful guy who will talk about speaker and crossover design for as long as you might want to discuss it.
