When I installed my Shearwaters I was advised by a more knowledgeable pal. He made a point of saying that levelling was important, and he suggested I use the Benz Micro round level that came with my cartridge.
I actually thought he was a little round the bend but I resolved to humour him once I got the speakers placed in the room. I was glad I did. Before that, I really only got the full imaging power of the speaker when I was standing up, just like you.
The next step was to add some acoustic treatment... I haven't finished that yet, but it's pretty clear that these speakers have an awful lot to give and room setup will let them do it.
