I have a set of the M-Audio LX4's and they are fantastic monitors. The BX5's and BX8's are also very good indeed. I had some Aego's but they did not compare well to the LX4's.
Ive read a few reviews for M-Audio LX4's and it looks like an interesting package. Whats even better is that you can add 3 more satellite speakers to upgrade it to 5.1, at a later date. Had I not gone the separates route, this might've been the package I wouldve gone for - a 2.1 set that gives me the option to go 5.1, should I decide at a later date.
So, in summary, for 2.1 sound the 3 packages to go for are:
M-Audio LX4 (around £160)
AE Aego M2.1 (around £90)
Logitech Z2300 (around £90)
General opinion seems to be that the Logitechs are not as good as the AE Aego M2.1. Given their identical price, I would opt for the AE Aego's, if I were buying blind.
I've just right this minute hooked up some Z-2300's and they have much much more middle and high tones then people give them credit for, they are amazing hooked to my X-Fi.
It depends what you are comparing them to though. If you have just upgraded from a sub-£30 pair of speakers, then the Z2300s will amost certainly sound better.
Another thing we forget is that personal taste has a lot to do with how good a speaker sounds and expensive speaker/amp packages are not necessarily going to sound better than the cheaper ones, for all people. Some people, to their ears, might actually prefer the sound made by cheaper speakers.
In my case, I prefer a tight bass (not big bass). The tighter and less boomy the bass the better. When I hear a drum beat, I want it to sound crisp and clean, with no reverb afterwards. After the drumbeat, I want its sound to dissapear as quickly as possible. To get this tight timing usually requires speakers/amps to be of high quality and hence, will cost more. Other people, might prefer the bass to linger for a few milliseconds, after the initial drum beat, so that the bass becomes muddled and drowns out other notes. This can be easily achieved by turning the subwoofer (if you have one), up to max volume and a cheaper system can easily achieve this. The bass will definitely be loud and may even shake the windows, but there will be absolutely no control.
In saying all this, the best sound Ive ever heard is through my Sennheiser HD580 headphones, but thats a whole other story.
