If cost is not a problem, the Sierra-1's are my choice. Going from classic 170's to these has been a quantum leap in performance. Not that the 170's ever disappointed me, but I can never go back now.
I was watching a movie last night with a friend. I only have two Sierras with a B&W center.....no surrounds hooked up and no sub, Sierras running full range. There was a scene with thunder. My friend was startled and thought a thunderstorm was outside! The impact from the Sierras is something that needs to be experienced.
