I was looking at the Epic 50 Home Theater as a possible packaged alternative, as it comes with the M50s that others have said are good for the music I listen to.
The funny thing about my 901s is that for some recordings they are amazing...particularly some remastered classic rock bands like Queen, Yes, Jethro Tull and Rush...for classical music and top 40 stuff, they are suitable as well...yet my leanings towards harder bands like Korn, Faith No More, Type O Negative, etc...they sound terrible. I really have to turn them up way loud to hear the musical nuances, and at that point the neighbors are banging on the walls.
As for movies, the Lifestyle 25...you just lose the voices in the explosions and special effects...so anything that balances things out will be an improvement to my current system.
