Moving Soon - Should I Pack Up Everything Now??

And, I have always had music during packing, last stuff on the truck; 1st off the truck, 1st thing assembled, music while unpacking, even in temp quickie setup.

I've got 3 systems, probably the basics of the shop/garage system would be last out/first in

I would say NOW!

I moved from USA to UK had everything set for the move. Shipping company, Airline tickets and all that. But I kept putting off actually packing everything in boxes. Boy was that a mistake. Came the day and in the end I had to leave a number of very useful things behind.Alarm clock, bed, dresser, pots, pans, dishes,silverware, glasses, cups, kettle,  Which in the end I have to buy all over again.

"But Joe, what about the all important stereo and computer? "

Oh, they were already packed.of course  I maybe procrastinator, but I'm no fool.

Determine what is your highest priority -- selling the house and moving or listening to music for a few more nights?

The emotional basis of someone buying your house is that they imagine themselves living there.  Do you think the average buyer will make an emotional connection with your system and imagine themselves listening to it?  The average consumer can relate to a big screen TV, a treadmill machine in the basement or a double oven in the kitchen, but not to audiophile systems.  Most will consider it an eyesore and as such it won't help the sale.

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.
