So basically, find the spots where my system sounds worst and then leave it there for 3 weeks so that things will improve... Hmmm, in a convoluted way I guess it makes sense because for a CBF to make things sound worse means it is having an affect. I just dunno if I can do that without second guessing myself each day thereafter. It's also relative. What sounds bad to my ears today will eventually start to sound normal - probably far before 3 weeks are up.
When I first started with AM stuff, I picked up the Quantum Studio, placed it on my main audio circuit and soon, to my delight, was quite convinced of its merits. Followed that up with a couple Ref IIs, a Ref III and a PE. Those required finding optimum placement, and that was a bit of a shot in the dark. I ended up putting them where I suspected they could do the most good - frig circuit, TV circuit, computer circuit, etc... Well, I thought that did improve things further so I just left them there. Then came the CBFs... I did try them in several places but was never really convinced (or perhaps never had the patience) to find "best" location (must less 'worst sounding' location). So I ended up leaving them also in the most obvious locations - on breaker, wrapped to incoming lines into the breaker box, and then strapped in various locations where I thought at the time they helped.
While I doubt I'll change the location of the active AM components, I may just do what Charles did, and yank all the CBFs to give a listen. Then, with ever most care, seek out locations for the CBFs that makes my system sound worse (what a sick, sick hobby this can be
