How many of us are truly satisfied with their systems?

Satisfied? Yes.
But would I upgrade if money were no issue? Of course.

Very Satisfied.... but always restless.......

I also went to THE Show in Long Beach yesterday, and of 62 rooms, I only heard maybe 5 systems that really impressed me.   Most of the rooms had a very boxy 100-ish Hz hoot to them.  I've been to several shows, and this hotel really had sonic signature to it.... not in a good way.  Only a few exhibitors somehow got beyond it.   My #1 fav room was Ocean Way!   

At the present time I’m totally happy with my system.
Just about everything sounds good if I make allowances for differing recording techniques. Some recordings, of course, sound better than others, but almost nothing sounds bad.  This is a place divinely to be wished for.

After those yearssss... and $$$... It is time to... only listen to my music and appreciate how good it sound to me... to you. Enjoy ze Music

I Had the owner of the top store in town come to my house a couple of weeks ago. I had reached a point where i had done all I could and thought it was very good sound. He was going to come and offer me suggestions on how to improve things. After checking my cartridge alignment, azimuth, vta etc, he had no adjustments to make and said, “you are hired.” Then we listened to music. He moved the speakers about ten times, till he returned them just where I originally had them. He was shocked by my high quality electricity (nothing else on the circuit). At the end, he said, “I wouldn’t change anything.” 
The guy who sells me stuff. It was nice to get his confirmation that he was hearing the same thing I was. 
So I am going to upgrade headphones and be done with my system for a long time. Just buy more vinyl. And a second listening chair. The end.
