Would Maggies 1.6 Benefit with Biamping?

2 Amps is THE WAY to go. Much better control, bigger soundstage, much better dynamics, less hifi and so on .....
Best are mono amps ( excellent is Rowland, cheaper but also nice are Quads ) but there are enough amps available I think.

I don't think you can do true biamping with the MG1.6 (i.e. using external active crossover). That's because the bass panel cannot be accessed independently (driven by separate amp) from the quasi-ribbon tweeter, unless you do some modification to the factory inputs. Check on the Planar Speaker forum of Audio Asylum for technical discussion of this issue. With the Maggie 3.6/R, which ARE built to be bi-amped, the setup is fairly straight-forward. I biamp my 3.6/R's, and it made a huge improvement in all areas.
