This is the best value dps you can get for the money!
I tried it in my home studio and live,it surely does wonders!
i also use it to route it in my bass amp as sent and return so i could get that extra features on my amp more eq and more compression!
Sound quallity is very good no extra hiss or ground problem and since it has all the ballanced connection it makes life easier,
But it could be better not hardware vise but software + alowing us to mod it also,,what do i mean by it,, adding on, bypass buttons in software for every path in chain eq,compression,etc and changing order of it,,also what would be nice to add midi support of software simple bypass option or change speakers like for example if you have 4 speaker on output, you could make feuture to mute one pair and play another,,, now for hardwar wise it could be great to control that software with a midi over arduino thats connected to usb on this dsp,,i thing these are crutial thing that needs to be done to be used in studio setting,,,
so conclusion time,,
is it worth it? YES
is it necessity? YES every big studio had some eq on the end of their signal path for monitoring.
is there better options? No i dont think there is any,,
Just buy it :)
