I had the chance to audition the RX8s this past weekend. I compared it to the B&W PM1 on an Arcam A18 and again against the B&W CM9 on a Bryston setup.
In my opinion, while the B&W have a certain silky smoothness in their treble response, the RX8 was clearly the superior, more robust, speaker. In my opinion they are a fabulous value. If you need a strong 2.0 setup without a sub, I say look no further.
That said, they are probably larger than what I want and will most likely go with the Dynaudio X12 or X16.
I just wanted to step in and compliment you all on the excellent speaker and share that I feel that the B&W CM9 (costing 2x as much) can't hold a candle to the RX8.
