Carlos,
Education designations/assertions aside, mixers at certain price points reflect the time spent in design, the cost of better components, and a broader, more complete feature set. They last longer and give a better result during that time. I'm sure you would agree.
I've just placed an order for an LS9-32, and although for me (a small band-leader) the cost is significant, I would not have been able to overcome my personal experiences with Behringer products to move in their direction - even at a significantly lower price point... even if I could get the product now.
One more thing: I've learned more than I've contributed on this board though I've tried to contribute where it made sense. There are many here who know more than I ever will, and humility and a willingness to learn create a more receptive atmosphere than pronouncements of any kind... even if you really know your stuff. The BS filter here is set on high, and I'm really glad it is.
Give yourself a chance, there's much here to be had.
Best regards,
Bob Charest
