Sure. I have an Audio Control C-101. I don't use the equalizer portion 
much, but when I need it, its a blessing. The real-time spectrum
analyzer display is a constant joy - and can be both reassuring (Jet
plane fly by at 6' on "Digital Domain" CD is not a tweeter buster)
and alarming (Other tracks on same cd could be). The display plus
built in pink noise source showed me all I needed to equalize 
speaker-room combination was some moderate treble boost as introduced
better by tone control on my integrated amp than by the octave
equalizer. So the equalizer is free for corrective action on source material.
For this and other reasons, I would put tone controls on a preamp. Many
designs are available that are, or can be made effectively out-of-circuit
when so desired.
As for phase shift, per se, you would be beter off not to worry about it.
If you must worry about something, try the weather or World War III or
some similar subject that is both simpler and more likely to affect you 
adversely.  Of course, if you are a true "golden ear" and can hear the
abdominal hairs on a flea rubbing together at 30 ft, even when there is
no flea, forget all this advice - but if you were  a "golden
ear" you would not be asking, you would be telling.  (Psych majors or
perhaps even minors will have recognized the signs of a Salieri complex
by now, but what the hell).
