Getting Personal Property Insurance for your rig.

My hi-fi is covered as personal property under my policy.
Yes, I had a claim ... once. They paid.
You need to speak with an independent insurance agent that represents many companies. Allstate agents only write Allstate policies.

I have Hartford homeowner’s and I have asked them several times if I needed extra coverage for an expensive stereo and large music collection and they have always told me no, that it’s covered under personal property. I have never filed a claim though and I’m still not sure that they will come through if needed.

That's how it works. Increase the value of your personal property to reflect your HIFI's value and take photos, keep receipts, and serial numbers.

For those who have an extensive and higher end collection of LP(s),
I would seek an independent insurance agent that specializes in such matters.  Most (read all) insurance companies will attempt to "cheap out" if a substantial claim is made.

@jafant , if you have rare, "collectable" LPs, then it would make sense to find an independent agent to insure these items.
But, as far as equipment goes, it's only treated as hardware.
