I bought a pair of Blue Herons about 6 weeks ago. They are still breaking in, but so far are absolutely fabulous.
Speakers are very personal purchases. How they work will depend a lot on the room, the upstream equipment, the source material, and your own taste. I have a fairly large room, good quality gear, play a lot of rock, and like speakers with visceral bass, clarity, dynamics, and musicality. The Blue Herons fit the bill.
I've had Merlins, Virgos, Khorus's, Spendors and other brands and it can be hard to find a speakers that just flat-out *rocks* like these do. Be careful that you have room for the Blue Heron's bass output, and don't use a tube amp unless it has some hair on it and can control the low end.
Meadowlark recommends 100 watts minimum and I hear Pat McGinty voiced them on Michael Elliot solid-state amps (http://www.ariaaudio.com).
