I am a big fan of DSP, as my posts show, but being an audiophile I want to hear my DAC and I want to hear my integrated amplifier doing what they are here for. I picked them for a reason.
For me to put an additional A/D and D/A component in the middle of that is not something I'd want to do. I try to keep my DSP/EQ in the digital domain, except perhaps on the way to the sub.
Still, I have to say that if you make your speaker sound great at a show you are obviously doing something right indeed.
