Ditto S7horton. Dave, your post is very appropriate. I have learned from my system and changes in the setup that speakers will reveal different nuances and qualities that at first you did not realize were there. Living with the speakers is the best way to learn this. I'd be willing to bet that many speakers on sale here are the result of guys who never heard them at their best for one reason or another. I have changed electronics and sources frequently and my speakers have revealed themselves to me in different ways throughout the process. Just being a listener to a pair of speakers rather than owning them will only tell part of the story.
