I purchased these speakers before the show and was initially underwhelmed. I have allowed them to break-in probably about 50 hrs. I did attend the show and do agree that they sounded great. I can tell you that since they have broken in some, that their sound in my room is now awesome. I do not have any room treatments and have not even insert the spiked feet and feel that my sound is close to the demo room. My wife even noticed the difference. Break-in period is 200 hours so I can't wait. These are definitely great speakers.
