You may actualy be able to schedule your stereo gear on a Musical instrument floater (or a personal article floater). It would provide broader coverage (maybe electrical surge/arcing) than a homeowners policy, probably lower deductible, offer, possibly, agreed or stated value (rather than actual cash value or replacement cost-neither buy you new gear)but, much higher premium. Your Homeowners policy in its standard form (assuming it provides theft coverage) doesn't have any limitation in its contents coverage (personal property of insured)provision for stereo gear, but, it is subject to your HO policy perils (fire/water/theft), deductible, and valuation provisions. In any event, the single most important thing you need to do is document your gear; original invoice's, ordering forms; I take time stamped photos and have even secured affidavits from my dealer over the years as to its condition/value as well as listeners (a 10 year old $50,000 amp would yield a few grand should it be stolen on a HO policy if you don't know how to navigate the waters). An HO policy with replacement cost provides "replacement with like kind and quality...". And that is (w/o your documentation) subjective by an insurance adjuster who has no idea a cable not made by monster can cost more than $100.
