Whoops, that discussion was actually on the ProAud list (pgm.com) - confusion 'cos much the same people hang out there. Unfortunately there is no archive kept for that list. However, as I remember, it seems that both minimum and linear phase EQ has its uses depending on material. For example, the way in which linear phase smears in time can lead to audible pre-echo (?) of low-frequencies e.g. an exposed bass drum. Similarly, linear phase may be useful when material is full of steep transients. Much of the discussion was ear- rather than science-led so some blanket terms such as linear phase "clouding a mix" should be taken with the usual caveat especially as comparisons varied between plugins and hardware. I think the general outcome was that both minimum and linear phase EQs are required for particular mastering jobs (perhaps why some plugins are switchable e.g. HarBal) If anything else comes up I'll let you know.
