It depends... But generally not. So much depends on the source material, and the target playback system. A lot also depends on how often you are recording, and the format. 100+ shows a year at 24/96 can make it hard to find time to make 16 bit versions, let alone carefully listen and EQ. And once you fall behind... I find post processing work rather tedious and not fun, especially when the weather is good.
It also helps to know your venue, placement, and gear well.
Once you apply EQ, the result becomes your interpretation vs. what was recorded. Are you trying to make it sound like the venue experience (and, btw, what kind of ear plugs were you wearing?), or your interpretation of something better?
I avoid EQ/compression/etc. I find it tends to smear soundstage detail, especially 3d placement. On some recordings that does not matter.
A lot depends on the "hi fi" system that is the target. What sounds bright on one system may sound fine on another. Do I want something I can crank in the car? Bass that sounds great on the VR4's may not work at all in a car. Are you targeting headphones? Low or mid-fi systems?
One thing I do always want... I want to be able to crank a recording without loud applause, whistles, etc, distracting me, or making me wince. Since I do a lot of 'tape from your seat', I tend to spend quite a bit of time dealing with those issues in a neat and clean way.. That can be very time consuming.
