Something to note is that I've found my CAMs to need much less boundary reinforcement than the 3xrs. The CAMs have more midbass and bass, which is of course due mostly to the larger driver. This is just my personal experience. I've read where others were satisfied with the midbass / bass of the 3xrs when used with amps like the Decware Zen. I'm a Pass Labs / First Watt owner, though I'm keen to try the Decware some day. Point is, there are many things to consider with amp / speaker pairing. Overall, I think the CAMs are probably the most versatile stand-alone speaker Omega offers, based on size, midbass/bass production, ease of placement, simplicity, and tonal balance. Note I haven't heard the dual RS5 based speakers, but their lower impedance could MAYBE present a little bit of trouble for amps like the Decware. It depends. So, this is something that adds to my assessment that the CAMs are probably the most versatile overall. Again, Louis is the man. He won't steer you wrong and enjoys talking to his customers.
