If you want to explore more - then also look at the Wharfedale Jade
and the new Monitor Audio Silver 1 and Silver 2
Ascend Sierra and Philharmonic are also nice options
Some good recommendations here...
I had the Jade 1 and it was really nice - one of the best imaging speakers I've heard, and very good resolution... On the other hand, it was bass shy and very inefficient. I'd say go for the Jade 3 if possible...
Then again, for $1500, I'd be looking hard at the Ascend Sierra-2 with RAAL tweeter.
Of course, the Philharmonitors are alot cheaper, and very good feedback on them...
If you are really interested in PSB, I'd say look at the Imagine B instead of the Mini...
