I own the MA6200. Recently got it back from service to repair the Tape button. This is a beautiful amp that mates well with so many speakers. I'm currently driving Sonus Faber Signums and I'm stunned at the bass control. I've only heard good things about both, but everything I've read suggests finding the funds to get the MA6200. Although, I might agree the MA6100 looks cooler. I've also tried the MA6450 with greast results as well.
