Looking for wider soundstage

I also have an option of trading places with my 6 foot sofa that I listen from with the longer 9 foot one that is blocking reflections. Is that an insignificant change or would that help out?

The photos help… what about your sitting position? It all matters.

I took pics from listening position. I think my listening position is as good as I can do. 

I would switch amp the SS amp will control the bass better and the tube on top will have a bigger soundstage and mids

I have an Aurender N10 changing my DAC for Aesthetix Pandora

Ridiculous, it is all setup and lack of treatments in the room. Nothing to do with tubes, ss, or the like. I have a modern tube integrated and ss integrated and in my room there is a slight difference from ss to tube.
