Moving Soon - Should I Pack Up Everything Now??

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.

@zerofox As mentioned above, have some music playing softly.  A little Chet Baker perhaps.  I spent most of my life in sales and can tell you emotions play a huge part in the decisions.  You are trying to seduce the buyer.  Your system may be what makes your house memorable among many the buyer has seen.  Another trick is to have baked some bread just before people come over.  The smell stays in their minds and produces good feelings about the house.  The last time I had my house on the market, I would vacuum the carpets just before a showing.  Without fail, you could track the footprints right up to the front of the system.  People just love to look at something they have never owned and it sticks in their head.  Use it to your advantage.  A little "please do not touch" sign should be all you need.  Have a little faith that other adults will show some respect.  After all, these aren't people off the street and there should be a realtor with them.  Bast of luck with the sale.  

I wasn’t going to trust my babies to just anyone, so a few days before the movers came,  I rented a trailer and packed everything in it and a few other fragile items.  I left a receiver and some Yamaha speakers so I wouldn’t be without music.

All the best.

I left my system standing while our last house was on the market. The horns needed to be custom crated--and the crates would not have fit through the door of the room. And where was I going to stash all the gear and records- at the time I had around 17k LPs-- I wasn't going to put that stuff in the basement despite dehumidification systems (and the horn crates would not fit through the basement door either). 

I just told the realtor--make sure nobody touches the tubes or any gear. When I told him some of the prices, he blanched, but got the message.

The presence of the system did not, in my view, affect salability. 

Once we went to contract, everything got packed, home theatre-- two 6 foot racks--were stripped of gear and disassembled, carpeted areas replaced, holes patched and painted. And we did it in whirlwind fashion. I packed the records myself, and supervised the packing of some of the heavier gear. Some was sent off to be checked by manufacturer before being put into a controlled storage facility (like they use for art).  It was pretty exhausting but we delivered better than "broom clean" to the buyer and in a fairly collapsed time frame. 

OP, this is really a question for your Realtor as it is their business to ensure your house shows well and sells quickly, at or above your asking price. I'm betting the photographer was their idea. I wouldn't be surprised if that photographer has instructions from the Realtor to shoot around your gear. 

As for playing music for your prospective buyers, what if they don't share your tastes in music? Ask your Realtor.

Personally, out of all the things you need to do to get your house ready to show such as painting, cleaning, decluttering, repairs, landscaping, etc. playing music for the buyers wouldn't make my list.

Good luck with the sale of your house!
