sounstage too big bad thing

Hmm, soundstage should be mostly in front of you, not over your head. You have some interesting but perhaps unnatural things going on, perhaps due to room acoustics?

Synergy is everything. Not all good pieces work well in every room to every ones taste. If you don't like what your hearing and cannot tame it otherwise then you should definitely make a change or two again until things sound right.

A bigger sound stage may require that you listen farther back than usual.

When done right and listened to from a location with an amicable perspective, it should be a good thing.

There can be more separation between instruments or recording lines and more air and space within the soundstage which helps our ears pick up sonic cues that help flush out details and overtones better.

It can be like enlarging a photograph. With enough resolution to start with and accurate reproduction, patterns and details can be detected by our senses more easily.

SOmetimes, also, it can just be your ears take time to adapt to a different sound stage as a result of some component change than they were used to before. A bigger soundstage should almost always be a better thing. You may have to tweak and adapt your listening perspective a bit to get used to it.

It took me a good month or two to adjust my listening to be able to get the enormous soundstage I created when I introduced the OHM 5s into the room they are in. It was so much wider in particular than prior, and so totally disassociated from the location of the speakers themselves, that I was totally missing the beauty of what was really going on at first when trying to listen to the speakers. The location of the instruments and recording lines had virtually nothing to do with the location of the speakers and my ears just did not get it at first. Though the speakers did take a while to break in, I think it was more it took my ears some time to "break in" to the new sound at first.

You're getting good advice.

Playing with speaker orientation/location to lock in the new soundstage the way you want is definitely the first thing to experiment with before changing anything else.
