Price an issue, or cost be damned? As I talked about above, I don't think you will find a $1500 monitor that would make ditch the M80s, in terms of imaging. But there are a lot of speakers out there that specialize in the audiophile realm in imaging. I could be wrong, but I think I could find a number of articles that put a monitor at the top of the speaker pile, regardless of price or cabinet. I'm sure others have opinions on this.
