Why don't more recordings have soundstage outside of speakers

@mahgister

You should have an internet site where we could send you , pictures and dimentions of our rooms .
And received advice from you about :
Controls of vibrations, control of electrical noise floor and acoustic control.
For my and others’  benefit

@mahagister
Do electronics ; power amplifier or preamplifier , have any effects
on the soundstage , holographic sound, etc. ?
I may change my integrated amplifier and wounder if I could only buy a power amp. I only use the preamp section of my integrated
for my Lumin streamer. But I could connect it directly to a power amp. using Leedh processing.
No need for the preamp. Section then.
Would I loose anything regarding deepness , soundstage ?
