Yes, I've noticed that. When your sitting in the sweet spot in front of them, you don't notice how loud it is until you move around the house. I have an open bungelow and if I go into the kitchen, I notice that it's really loud and have to go and turn it down. Plus I can be in any room in the house and still hear every detail in the music and voices as clear as day, so that's testimont that they're reproducing a true source of sound in my mind.
Congrats guys on the new 28B!

That is interesting, my 7BSST with PMC speakers and room acoustics does the same impact but in lower volume levels.

The 28B are great with exotic speakers costing twice it's price. However, I am sure a bookshelf or stand mount will work with careful volume levels.
Ultimately, I heard the 28B with a Rogue tube preamp and B&W Nautilus speakers in Son Ideal, Canada. It is simply Awesome! I didn't compare it to other amplifiers in the dealership though. The room it is in a good size room and has good acoustics. You hear a good balance of sound from top to bottom even at low volume levels.
My point is that even the 7B can achieve such balance. Interesting findings for me.
