ARC preamps with HT bypass have an input or remote button labelled "PROC" for "PROCESSOR".
I build my own speakers, so do a lot of in-room measurements. The two places where DSP / room correction turned out to be critical was the subwoofer and center channel. I decided to get a miniDSP. It's kind of a geeky solution for most though, but in my setup it works wonders. I have Zero DSP on 2 channel listening, and when movies start up it's a seamless sound.
I also did some room acoustics, with a pair of GIK soffit traps and 5 panels. I'm very happy with the tone. Now I'm thinking of an ARC 2 channel preamp for better imaging. We'll see.
