Just plug and play without isseu? Nice. I was considering the 7xx option as well as I now believe the 1480 is a more complicated system with multiple amps, etc, and likely not viable. Also, I've read the Becker aux mod resulted in mono sound, which does not make a lot of sense; why would someone go through the trouble and cost to install an auxillary source input only for it to lack the most basic of fidelity features? It also doeant seem in line with Becker's sensibilities, not to mention MB owners'. Anyway, does your experience support this notion the Becker auxillary install is mono? Thanks
