Definitely interested to hear your feedback! I don't even have my DSP.3 in the car yet - but I have it setup "on the bench" and plan to start messing with it very soon. The built-in RTA seemed kind of cool, I just haven't heard much about it (I think it's pretty new?). I'm brand new to Helix, so it's all new to me right now. :-)
Thanks for the feedback - I appreciate it!
