I’ve learned that I have to hold something in my hand, set it up and use it, live with it for a little while, before I know if I’ll like it. Some of that is build quality and control feel, some is sound, some is ineffable.
I know this is easier for some than others, but I would try. Get used gear and resell it when you’re done. It’s really worth it. It’s the only way to really grow in this hobby.
Also as it turns out the room itself is key to how something sounds, so yes you are entirely correct.
