I was thinking about this earlier... Why not order M2's and a EP400 that you are thinking you want.. However, order these items in a stock finish, if you decide you like them, then return the stock finish speakers and place an order for the custom finish you want. This way you will know that YOU like the setup before paying the premium for the custom finish which can not be returned and not having the ability to try something else if you decide you want to.
With this option, you could order a pair of M2's as well as M22's, then decide which YOU like the most.. Also, if you find the EP-400 is sufficient for what you want great. However, if you decide you want something a bit bigger you would have that option.
All of the above would cost you some shipping $$. But, you would know exactly what your getting and positive that it IS what YOU want.
Anyhow, that's all i got.
