There is really no reason at all to think that linear phase EQ
would provide any advantage or be required. Almost all physical
processes that modify a frequency response (e.g. resonances)
are minimum-phase, not linear phase. The minimum phase response
is in a sense 'natural', it's the one that requires the least
internal state and it can be the result of a very simple physical
process.

This is the reason why sounds that have a fast attack and an
exponential decay (a 'ping', min-phase) occur much more easily
that those that do the inverse (a 'gnip', max-phase) or have
a symmetrical envelope ('gnipping', linear phase).
