The Mira 2000 had a leaner, brighter balance than its clamshell predecessor and it's my belief that the current crop redress this to a large extent. My advice would be to go higher than this level to get any real sense of improvement and there are many alternatives out there for you to consider. At this point, not sure if I should dive in with specific models or makes, but there are many many threads here going back all this site's life with 'our' favourites being recommended time after time
Have fun researching...
Tear down these walls; Cut the ties that held me
Crying out at the top of my voice; Tell me now if you can hear me
