40.1's have about 30 hours on them and the sound is incredable. What I have found is that if I place the 40.1's in the same position that I had the SHL5's in, (3 or 4 feet from the back wall) the sound stage and imaging disappear. They must be 5 or 6 feet away from back wall to sound best. They are a larger speaker and 5 or 6 feet out from the back wall kinda puts them out in the room much more which is not setting to well with my significant other. However, when she starts her protest, I fire them up and the incredable high's and bass takes her away for the moment. I'm currently working on some corner traps that may ease the situation. Will report back. As I stated earlier this really is a completely different speaker than the SHL5. Bass response is much deeper and highs are very pronounced even at a low volume.
