So my current 5.1 Logitech speakers are kind of going out, and sound terrible now. Well, not really bad, but after mixing a song in my BX8a's (which are huge and prestine) - listening to the mixdown through the Logitech's sound incredibly bad, the whole fidelity in quality sounds horrible one my ears are accustomed to the big monitors. So I was looking around for a better solution, something that sounds good for everyday listening and also is of high quality so after mixing in the big monitors things don't sound all too bad. Looked at the Logitech Z520's, guess those suck. Looked at the Z2300's, I guess those aren't too good either an have absolutely no midrange. So then I came across the M-Audio AV40's and everybody loved the sound out of those, which didn't surprise me as they're made by a professional audio company you know. So I'm sold on these AV40's which are $150. Well then my buddy tells me he has some BX5a's sealed in the box he'll give me for $150, which retail are $300, so half off. Now I'm in a split decision between the two as to what pair woulf be better for my everyday listening. Suggestions?
