I use APS AEON studio monitors for over 2 years and they are my main working tool in the studio.
About
sound quality - its superb! Nice option is the ability to choose tweeters - titanium or material. In my monitors I have titanium tweeters, and I have to admit that they are very precise and not fatiguing. Midrange is not put forward but it is very detailed. Low tones are clear, quick, and they go pretty low!
Easy of use: what can I say, turn on, and they work.
Features: On the back is adjustable input level, tweeter, bass boost, ground lift and bass controller. Interesting option is the ability to disable bass controller. This makes the low frequencies fast and precise. If you want to see what happens on the 30Hz - turn on the bass controller and regulate it. Pretty good option. So i dont see necessity for sub.

About the aesthetics - my monitors are in standard black color but you can choose ANY color.
Bang for buck: They really well built (not in China but in the EU), the electronics is in a separate room behind the rear plate. (

AEON's are great studio monitors! Their quality wins with far more expensive speakers.
