I havn't listened to the Monitor Audio's, but I think you can do better for your money than the Monitor 7.
Listen to more speakers in that price range.
When I first started auditioning I listened to the Monitor 7 and then Studio 20s,40s and 60s. I could not go back to the Monitors as the Studios delivered so much cleaner sound. Since the Studio line was out of my price range I looked for alternatives that would give me a similar sound.
I havn't heard the Swans, but they seem to get good reviews. My sig tells you what I found.
