Why do some amplifiers throw a bigger soundstage than others?

Very interesting thanks 

...

If love or music as some specific arrangement of sounds cannot be measured as such do they exist ?

A children will say yes...

Soundstage is an acoustic perceived parameters pertaining to many contributing factors with are related to the electrical, mechanical and acoustical characteristics of the gear /room but also to the inner ears frequency response and to the HTRF of each one of us and also to the recording acoustic trade-off choices of each specfic album...

Soundstage cannot be measured in a simple linear way but it result from a perfectly contrallable set of parameters.. I put it under my own control in my room and sculpt it in a way and the form i wanted too ...

Most things exist in spite of being non measurable in a simple way or even in a complex way ... Galileo eliminated what is not simply measurable, as taste ,colors,sounds,odors and feelings and called them secondary qualities. not measurable as the primary qualities : size,position and location , form and motion to start physics...

But physics as it is now is a drop in the bucket of knowledge ... 😁

We need a new physics by the way...

This dude in India work to create a new physics among others..

If soundstage cannot be measured, does it exist?

« This thesis investigates the extent of the human ability to perceive changes in the
direction of low-frequency sound sources, within the range of 31.5 and 100 Hz, in
a large, highly damped environment.»

... «It has also been demonstrated that the
presence of modal behaviour in the listening environment hinders the localisation
ability, as it leads to erroneous ITD cues. This fact could have contributed to the
belief that, as a rule, low-frequency sound sources are not localisable, a view which
this thesis aims to refute.»

Mapman is right because he exposed almost all factors..

i will add vibrations resonance control and the room/house electrical grid factors...

The main factor , save if the design of the gear is not very good, room acoustic controls... For sure it takes a good amplifier but it is one of many factors...

With the same relatively good amplifier i can transform completely the soundstage impression by modifying the room... I did it by the way... It is not an opinion but a fact...

My soundstage was filling completely the room around me and beside me with no sound coming from the speakers plane ...the main fact was not my choice of amplifier , even if the amplifier must be minimally good for sure otherwise nothing work well , but the main factors was acoustics understanding and disposition of many devices of all kind to do the job ( resonators, and others devices)

But atmasphere explained why some amplifier do a good job and are better than others for the soundstage and timbre...

At the end it will be acoustic room disposition though the main factor...
