The 12s went back to factory because of failure of the switching power supplies on one and noise from the switching power supplies on the other. The 8 doesn't use switching power supplies.
Yeah, I have a comment: I wish I could afford one! I would love to get the Concentra integrated. One day possibly. JR is some of the finest audio gear in the world at any price. My recommendation: Like Nike says: Just Do It!
I've owned a Model 1 since '93 and am very happy with it. On first listening it seemed laid back, even reticent but with time it simply disappeared to let the music shine thru. It's lonely so I'm looking for a second so I can run them bridged in mono.
