Similar to you, I listen exclusively to Germanic-Austro-Hungarian-Russian classical music from the 1790s (Beethoven), onward. For me, it just does not hold if the soundstage is not there. I need to be convinced that I am sitting in front of an orchestra. Speakers are the rate-limiting-step in soundstage reproduction. I think you are correct in putting soundstage as a priority in your listening. In addition, detail and sense of scale are very important. You need to strike the correct balance between detail/bite, and smoothness/lushness. If it is too smooth, it becomes boring for me.
Once you find a speaker that accomplishes your goals, there is so much which can be done upstream to refine and fine-tune the sound.
Also, do not become speaker poor. You will not enjoy your expensive speakers if you cannot get the proper amp for them.
