We got to use our new Presonus Studiolive 24.4.2 last night and it was as if we had an entirely new sound system. I never thought our PA would/could sound that good. I wish we were able to purchase one of these months ago!
If you are considering one, I highly recommend taking the plunge! Since the new AI versions came out, the original Studiolives have undergone pretty drastic price reductions. I got mine for 50% off of MSRP through Sweetwater.
Next step: in-ears all around!!!!
