I'm having a hard time picking which speakers to get. I haven't heard neither speaker but read good reviews on both pair. I have a Onkyo TX-NR 906B receiver to run a good pair of speakers. I also will be buying a HSU VTF-3 MK3 Subwoofer for the sub. I found a store that carries the RBH MC 6 speakers but I can't audition them. ( They say there in a warehouse ). And Audio Advisors in my area sells the B&W 685. My room size is 20X16 with 9 ' to 12 ' ceiling because its vaulted. Which one would you choose ?
