I can't say the actives are the last 2 to 3%. I was never able to achieve with the M100 or any other Axiom what I've achieved with the actives. The actives, flanked by twin 500s, are all I could ever want. The 800 is icing. For the first time in 13 years, I can't see how I could possibly upgrade to anything else.
