The part I and part II clips are fully over the top - excellent and noticeably improved. They are "Ready for Prime Time".
However, Part III (in my humble and honest opinion) while very very good, does not quite hit the same level of excellence. I hear a distinct boominess and slight low end over emphisis on the second half. I cannot say that I am hearing a 100% match. (listening on Dynaudio BM15s) Of the three, part III does have room for improvement before we can say it is dead nuts matched.
You are almost there on this one Cliff. Good work chipping at this stone on this one and you will get there.
