As yet another who has worked in the sound industry for years. I must make an obsevation, I have always worked as a sound engineer doing live music, I have friends who work as studio engineers. What I have learned don't let a live sound engineer mix your cd (unless it is live), don't let a studio engineer mix you live. We look at things very differently and never let a musician mix anything. I do not play an instrument other than my board it gives me a different perspective.A Musician will favor what they are used to, studio engineers will take the ambiance out of the mix, and guys like me will add effects to create ambiance. What I have noted with my 950 is I don't have to turn it up so loud to get the desired effect, I love it my ears and neighbors were tired. I like the PLII-M best for most things but it really depends on how the CD was mixed.
