Yeah, no disagreements. I have a firm belief that the tracking process being right is paramount to a great mix. But I certainly don't believe that's where the expense ends. Even the best photographs in the world need some element of post-processing at the cost of chemicals, dark-room, or Photoshop. Use of the wrong chemicals or cheap Photoshop plug-ins can actually hurt them.
Here, use of a low-cost reverb might actually do damage to a great recording. Use of a highly erratic compressor can destroy transients vs. enhance them or thicken them up. Graham is right in every respect and I am splitting hairs here. I'm just emphasizing that sometimes a plug-in
will help a recording sound even better. In the case of Sonar, Cakewalk has included some that are profound. I simply suggest that "we" don't take his message into the context that you shouldn't bother with other plug-ins. Just take Graham's approach to buying them.
I'll also throw in this last tid-bit. If you see a sale of a plug-in you've been pining for, give it a thought.
