While this has been discussed at length throughout the forum I thought it might make sense to try and consolidate it down and really break into what people mean and what is and is not working. While people often gesture back and forth on what’s best, I think we really all have the same goals in mind weather we tune every track or tune the initial setup. Obviously making adjustment for every disk is going to yield the best sound as every disk was mixed on a different system and its naive to believe that there is one ultimate system, but at the same time that prospect of trying to zero in on the engineers setup for every disk seems challenging and time consuming (depending on your definition), with that I imagine a lot of us try to optimize a system that can average between your various setups.
With the above, said, what methods do you use to setup your system (absorption, diffusion, resonators, mass dampening, plinths, electronics, etc.) and what has worked. Also if you tune your system for various albums, what changes are you making, how long do they take.
I think it would be helpful and interesting to see how people have blended the various options together to create their system. Also having a discussion on what people are finding in their setups may help us all narrow in on changes that could take.
