apart from the delay, linear-phase eqs introduce pre-ringing, so they 
are a very mixed blessing. they don't change the fundamental truth that 
you cannot alter the frequency response without altering the temporal 
response as well.
morale of this story: use the minimum eq necessary. the lower the Q, the 
less phase problems you will get.
as david pointed out before, graphic eqs with bands of major thirds 
necessarily use rather high Qs, and you will suffer their adverse 
effects even if you set the sliders to "gentle" curves.
there is no silver bullet for this problem. or, as jack developer jack 
o'quin in his infinite wisdom once remarked, "you can't bullshit an
