I do have a sub, but I often forget to include it since it is not a new purchase. It's a JBL PB10, which does the trick for now and should compliment the M22s fairly well. I suspect that a new sub will be in the not too distant future, since the PB10 is great at the theater booms, but probably will not cut it on the music listening....We shall see.
I think that I'll stay the path for now and trust in my purchase. Perhaps I will do as Tom suggested and pick up a pair of the Athena's later for kicks and see how they stack up. Thanks to everyone....I think that I've shut that pesky voice up....for now. Let's hope I can keep it that way when I begin to wonder if I should have taken my original path w/ the M60s.
