I put the teac in the main system tonight, the little thing keeps over performing. When hooked up to the 12's it sounded great at lower and medium volumes, compairing it to a bryston 3BST. Starts to break up at "my" normal listening levels, 12x25 room. I went through an NAD and a rotel before the bryston trying to find an amp that could control the low end on the 12's. At lower levels the teac had the same nice control as the bryston. Imaging was great, maybe a little more detail and air than the bryston, maybe wishful thinking, but very similar. For a smaller room at mid volumes it's a nice combo. Still not impressed with the W's though. The image was better properly set up in a bigger room, but they still had a hollow or megaphone sound. Maybe this is from switching back and forth with the 12's which are 4X the price. I had MMG's before, and their much closer to the sound of the 12's than the W's. If you want the W's for wall mounting reasons, I can't argue, but the MMG's are well worth the extra $250. I heard the MGMC-1's at a dealer and they sounded great, wall mountable but even more $$.
Good luck, Ryan
