I listened to them some more this morning, since I am able to turn up the sound more. I live in a single story house, about 1650 sqft, and the M3s' sound filled the entire house without effort playing stereo Jazz music. I love how the instruments sound like they are right in my face, without being too much. Trebles are nice and crispy and the mids are warm. and since I have these hooked up to a small computer speaker sub, the lows are quite pleasing as well. These are beating out my older Yamaha floor standing speakers right now... Can't believe it, and I can't wait until I can pair it up with my future Denon 3805 A/V Receiver...
