I've tried a few pro GEQs on my L/R speakers for full-range EQ. They always introduced way too much noise. Not a problem for subwoofers which can't reproduce the higher-frequency noise, but a huge problem for the mains.

I also don't like the idea of inserting another set of DACs into the signal path, after I paid a bunch to get good DACs in my processor to begin with. You could go completely analog on the EQ though.

Another problem is that there's way too many frequencies once you leave a subwoofer. And ideally you should use PEQs because 1/3 octave is too coarse. I might give a go at things with the FBQ2496, but not interested in doing that right now. Building acoustic panels instead at the moment, for my surrounds.
