Also true.
But some guys have 4 different audio systems just because they have 4 rooms and they want something in every room. It’s part of the addiction of the hobby.
For example, you might have a 26’x22’ dedicated HT room with a 5.1.4 ATMOS system. But then you also have a 24x22 family room just “sitting there”. And you think, “hmm, that’s a great excuse to have a 2Ch system in the family room!”
