Ned, I know that because I've thought about it this much, there's no turning back. :-) 130 reviews of the Ah! 4000 on Audioreview.com and most everyone is glowing.

What's funny is my friend asked me "do you really need this"? I told him I don't "need" any of this stuff.

I'm one who happens to think softening up the music on my M60s will be beneficial. Maybe the Ah! will do it.
