Someone told me with my music you must listen to these B&W's. He found it much better with bright sound metal records than Tannoy XT6F/8F, MA Silver 8 and Q acoustics concept 40. What are yours experencies? To hear it i must ride 1,5 hour. Also experencies are welcome. Normally these speakers too expensive, but secondhand is a good option. And what's the difference between the CM9 and the CM9S2?
