I have IB2's as mains and center with LB1 rears. I drive the IB2's with 7Bsst's. Specatular combination.
In terms of digital front end, I use Prism Dream DA-1 DAC with a less than optimal transport (9000es). The Prism is simply outstanding. In fact, James Tanner, VP Marketing of Bryston used this DAC as his reference for many years. New, this DAC would have been $7k to $8k but because it is a pro unit and audiophiles don't know about this gem, you can pick one up for about $1.5k used. I was introduced to the DAC through James and was floored by it. Found one used with the help of Google from a pro dealer.
