I love the Klipsch speakers I use (see signature) but agree if they are crossed over too high they can sound shrill. Don't cross them over above 80Hz to avoid this. Other speakers I have heard don't seem to have the crispness of the Klipsch. As I would have to spend about $3000 or better to truly upgrade my speakers, I have been very satified with the Klipsch and the mate quite well with the Outlaw 755/990 I use. I will upgrade my projector next and doubt I will get to speakers for some time and am in no hurry.
