Reply to Echo Audiofire2 vs. Audio 4 DJ

My Audiofire2 is recently being shipped away to get repaired after some technical issues with it. Good thing that it's still covered under warranty!

But anywas I was wondering how did the sound quality of the Audio 4 compare to that of the Audiofire2? Did anyone use both soundcards to notice any difference? I know the Echo soundcard has very good sound quality but I'm not happy for the following reasons;

- I don't like the firewire connection. I believe it's flimsy and has a tendancy to be loose fitted.

- Im believeing of mixing externally. Basically just to add on to my setup and be able to use a club mixer when I feel like it. Seems like you cant earn any respect around here if you don't use the clubs mixer for some reason.

- I don't like fiddling around plugging in my Echo soundcard with the 12 V power chord.

So how is the sound quality of the Audio 4? Or should I just wait and keep my Audiofire2?
