This is coming in late for you previous posters, but my experience with the Model 7 has been in the past few months. I haven't been impressed with he Quattro or the 5a previously regardless of the amplification. I have driven over 150 miles round trip to demo front end and amplification products to hear them with my own speakers, vintage audio physics. With that qualification, my dream speaker is the Model 7. I have heard them with AR, Ayre, and Aesthetix amplification, digital and analog, and it made no difference, shockingly realistic artist in the room presentation. The price reality is that my MB convertible is currently priced lower than this speaker puts me back in my listening room.
