Just bought 101e's two weeks ago, and then bought the 6010d. They need power! Did I mention they need power? I really liked the 116s too, however, personally I thought the Usher BE's had their own advantages at a less expensive price point. I think the 116's would benefit greatly from a sub whereas the BEs don;t need one. MBLs aren't real efficient,did I happen to mention their amps will need cojones? I am running the 101e's with VT100 on the bottom and MC2000 on top because that is what I have, but therein lies the next upgrade as the dynamics are restricted.
As far as room considerations, I have an entire wall of glass, with a brick fireplace behind them, and they still image strongly, they sound great considering slap-echo is a mild term for what I have in the house currently. I've had JMLab Alto BE, Sonus Elector Amators, WP6.0's and Revel Studios in this room, the MBLs are by far the least affected by my "acoustics".
cheers!
