Congrats targa02 on your Lumina speakers, they look stunning and I have no doubt they sound incredibly outstanding!
As has already been said, it's a good idea to wait until fully broken in to make any amp changes. I think I just discovered something about break in with my recently acquired X3s. The bass was unpleasant at first unless I tuned the gain down. I experimented with chair position and concluded I had been sitting in a room node causing issues so ended up with the chair 1' 10" further back, and the gain now close to max with great sounding bass. But I just now sat in the original position and the bass is clear and clean so perhaps part of what is going on is due to break in.
I can also state that my experience with Spatial speakers is they seem to come alive and maybe even need more power than their specs would indicate. With the M3 Triode Masters I had they sounded quite a bit better with the Mivera class D than with a 10 watt Dennis Had Inspire amp.
