Insurance for system

Home insurance typically has a set limit for personal possessions, and it's usually a percentage of the property value.  You need to concern yourself with the specific coverage limits set out in the contract.  It is quite normal for limits to be placed on Fur Coats, Jewelry and individual pieces of art (as examples).  I have never seen a limit on stereo equipment which means it would all be covered under the total umbrella amount.  The most important provision is coverage for replacement cost.  In this case, you are guaranteed to be able to get the same gear.  In fact, if you don't replace something you will only be paid the  depreciated value.  Pictures are a good idea.  Receipts aren't that important as the replacement values are self evident.   Just read your policy or ask your agent if limits apply and if replacement cost is covered.  The policy is required reading as bad information from the agent won't help you at time of claim.  Cheers.

I revisited insurance coverage on the hifi and record collection when I moved from NY to Texas at the very beginning of 2017. DOT insurance is by gross weight and a joke. I was covered by Chubb, which I started using years ago- they insured various exotic cars I had for less than what they charged for a daily driver.

I have riders for the hi-fi, the records, and some other high value stuff. A year or more ago, we finally parted ways with Chubb- though I thought they were very good--their premiums got crazy. We switched to a company called "Pure" which writes for high value assets. Hopefully it is never going to be an issue.

Lloyds will insure just about anything of value, for a cost. But maybe just a rider on your homeowners delineating all your audio stuff.

As stated by others, stereo equipment is covered under the personnel property coverage of your HO policy. However, records are considered media and may have a specific dollar limit. Read the policy 

What you’re looking for is called a Personal Articles Policy. It’s used to insure things like art collections, stereo equipment, and other expensive collectibles. It’s one of the cheapest insurance types to have; don’t try to list these on your regular homeowners or renters policy, as it will be really expensive and/or you’ll max out the allowed scheduled amount. A seven figure Personal Articles Policy will run you two or three grand... Ask your broker about adding it to a homeowners or renters policy.
