Open House With Audio Components

I would at least pack up the turntable if you have one.

Suggestions to rope it off are good, but if your move will be soon, why not pack the whole system up now, and not have the possibility of damage?

I would pack it up. People who don't appreciate audio will see it as wasted space. Usually when staging you want to take a minimalist approach. Comfortable but with space, potential buyers want to imagine how they will use the space.

It’s hard to predict what potential buyers and looky loos might do. I wouldn’t take a chance. If you’re contemplating changes to your system in the new home, this is a great time to sell some equipment. If your realtor stages the house, which they do very successfully in California to help sell the home, it will all end up in the garage anyway. I’m speaking from my own experience.

Pack it up, guns too. Get names of who enters the house, sign in.

Why do an open house at all?  They don't really help sell your house, but are actually a marketing tool for the broker to collect names of potential customers.  That said, there are other really good reasons why you should disassemble your system when attempting to sell your house.  Good luck!
