The biggest difference between the stock Ninja and the Ninja Master looks to be the price\:D, ummm, this is what Sean said to me

"... overall the same improvements will be heard. The difference is the resolving capability of the Master version is superior as well as the area of transparency. Bass is a little better with the Master version too."

Now to me, judging from this, since the M22 needs a sub to really fill out the low end any way, it makes the Ninja XO the more prudent choice for an evident change in sound, considering diminishing returns and all.
