Yes, I believe so. I think there is an optimal position for loudspeakers. I spent many hours working with an eighth of an inch to place my Alexia Vs with a lot of help from Jim Smith. Everything locked into place and it all just came together. There are always trade-offs to every position but In my own experience, there has been one precise spot where everything just works.
so then what happens 3 or 6 months later when as you listen, maybe you visited a buddy who does it differently and you like it, and you decide to change the position and then you prefer it in the new spot? maybe you like an acoustical treatment that allows a different spot? any sort of different perspective.
which does not mean the first spot was not just fine. but something changed; maybe you and your reference.
the idea of a
"ONE TRUE SPOT" is just not viable logically, i don't care if it was a bolt from heaven that choose it. it might be the best spot that can be determined at that time based on the information and mind set available. but things change. we have to realize we never know everything. stay humble, but also feel good about where we are and fully live in the moment. otherwise our ears close to opportunities. our ego gets in the way.
just my 2 cents. in my room journey i got humbled dozens of times. finally learned it was part of the process. still is.
it is perfectly fine to view your speaker location as great and good enough that you don't want to mess with it, but that's a different idea than knowing it's the 'ONE TRUE SPOT".
