yes cfh i agree that for most people it is an expense but it is a historically viable integral part of the chain for professional production. on a budget, its one of the last things to buy but again, the cherry on top analogy. you still need batter, dough, eggs, etc. etc. to make it but it's a nice touch and changes the way you mix.
ITB has come a long way i remember james murphy in a post a few years back talk about how pt hd has evolved so much where it has its own sound and for guys who like modern clean cut metal productions ala andy sneap then digital summing is its own tool, and another type of cherry to put on top of your cake. but dont disagree with the quote of mine you put in your reply where i basically call out people who knock it as "useless" because it is not USELESS at all. it is quite useful just when working with a budget one of the less important things. i'm more irked by people who say it makes no difference and is a waste of money than people like yourself who admit it does something but is not a necessity.
and again, im super curious if andy albums from 03-05 or in that time period were analog or ITB.
