How to protect against burglary

An 8th degree blackbelt in Hapkido, or a pump 12 gauge shotgun should do the trick. A security company will do nothing for you but (hopefully) alert the police to a break-in well after the intruder is done stealing your system.

Forget the security companies, get a rider to your home/renter insurance policy that covers your audio equipment with a no deductible, current equal replacement.

A good Rottweiler or canine equivilanent, but nothing is foolproof. Insurance riders are available.

Yep, I find that a 70 lb. pitbull will ward all but the most determined burglars. And it is a portable protection device as well...

You should accept the fact that you cannot prevent a truly determined/skilled thief, but what you can do is deter the amateurs. I've read many times that thieves dislike homes with dogs. It doesn't have to be a pitbull or such, but the mere sound of a dog, or better yet dogs, loudly barking is a strong deterrent.
