I was curious so I dropped by the normal publications, and while they are not comparing monitors to M80s, some of the descriptions make clear the monitors tested rank pretty far up there in the speaker hierarchy in terms of clarity and imaging. I hate to post links to other speakers, but for the purpose of discussion of the image available from monitors v. towers, the following may be informative.
