I've heard the Wind Rivers and have owned the larger Tetons for about 6 months. There are a few of us Teton owners here in Audiogon who have commented on them in other discussion threads - always extremely favorably. While the Wind Rivers may seem like small versions of the Tetons, they are by no means small loudspeakers, and put out a very large impressive sound, with wide deep soundstage and great imaging, excellent detail, and quite prodigious bass when it's called for. And, most importantly, they're very musical. I would be happy to host a Teton-listening session for you. Do you live anywhere near north-central New Jersey?
