Moving Soon - Should I Pack Up Everything Now??

If it helps sell the house leave it up. Highly doubt you will get burglarized unless you have Gucci displays  and ATM's in your house.  Most will be clueless.

If you're moving due to a dissolution of marriage, I'd recommended packing up everyting NOW.  And, anything else that has value to you.  Including the water out of the waterbed.

I agree with @bigtwin.  If you are going to be living there for a while, then leave the system set up so you can listen.  Mostly potential buyers want to be able to visualize what they would do with the various rooms in a house.  Your system does not clutter up the room and should not have a negative impact. 

If you are concerned from a security aspect with pictures of your system being posted in the listing, then buy some dark sheets and cover the speakers and components when the pictures are taken.  Open houses are another consideration.  Unplug your system, put the speaker grill covers on and, if you don't have speaker covers then, maybe buy a couple of heavy duty winter AC unit covers to put over the speakers.  You don't want somebody or their kid poking their finger through your drivers. 

At the very least, definitely put the grill covers on the Wilsons. If the speakers in any way protrude into a walking path, consider moving them closer together or closer to walls. Open houses can get busy, and there are often growing families where children are not always monitored. All it takes is one toy scraping on the side of your speakers to make you regret not packing them. 

I agree with others that a staged environment helps more than hurts, and your setup is fairly minimal and looks sophisticated. Little details like that gives prospective buyers a quality of your character, which adds to the confidence of buying the property. 

Best of luck!

Good Luck with selling your house.

Your level of equipment you own warrants being put away. You do not want pictures out there unless you are selling the equipment. I sold my home 2 years ago and thought I would wow people with my background music. I then opened up Pandora's box. Some people wanted it included with the sale. I also had a person who looked at the house call and wanted to know If he could come back and show his friend the system.
