1Plus2 is better, higher end sound, stronger technically and the bass is unmatched (1Plus2 dynamics and bass impact are just to strong) however for a fraction of the price I think $400 for RDB+ v1 Mini is still a good 75-80% what 1Plus2 offers IMO. They certainly sound like they're similar gene pool or blood line. I could of purchased 1Plus2 unit but stayed with $400 hybrid for now, rather than outlay an extra $800 odd dollars on top for 1Plus2. I'll stay on this and meet a sane level of diminishing returns.
Very happy with the Mini, I wouldn't of bought it otherwise. My decision made after demoing both 1Plus2 and RDB+ v1 Mini for lengthy amounts of time.
Thank you two of you
Look like 1+2
