These are my first REAL monitors (I've used many, but never owned, so I can't really compare them to much, other than the Creative Labs computer speakers w/sub I have used for... too long).
These sound very transparent- just like I had hoped. Testing some albums that I like, the definition was notable, and quite pleasant.
(Mind you, monitors are not meant to just sound "good", rather they are intended to be ACCURATE, and then it's up to YOU to make them sound good). In that regard, these deliver) Listening to some of my own material I was (mostly) pleasantly surprised to discover details I was unaware were hiding in there! Sadly, they also revealed some of the issues with my old monitors, as well as my own technique (sigh) though mostly I was relieved to hear I had done alright with my cruddy old speakers, but WOW, what I had been missing!
I think they're just a little bright sounding (in my room which is less than ideal), easily addressable with the various attenuation knobs and switches on the rear panel (thoughtful/useful features for this price).
The bass presence is quite satisfactory, clear and defined- not earth moving, which for me is fine (there is an available subwoofer for these if you're THAT kind of composer- you nuts).
