Ethics Policy: How We Stay Independent
The Shelfline Compendium stays independent by refusing paid listings, sponsored content, and paid placement from audio retailers, installers, or equipment manufacturers. We do not rank products by affiliate commission or advertising spend. Recommendations are earned through direct experience, technical merit, and community trust. This policy is binding across every page of the site and every update to our recommendations. Independence is not aspirational—it is structural. No advertiser account, no revenue from referrals, no affiliate fees that vary by product or vendor. A reader who doubts whether a recommendation is genuine can point to the absence of competing financial interests.
Our independence, in plain terms
100% reader-supported · 0 paid listings · 12+ years of independent reviews · Affiliate links disclosed on every mention · Recommendations withdrawn immediately if issues arise · Conflicts of interest reported within 30 days

The Reference Rules
| Recommendation Type | How It Is Earned | When It Is Withdrawn |
|---|---|---|
| Core recommendation | Direct use over 6+ months, documented performance, community verification | Failure to perform, price change beyond market range, vendor conflict, safety issue reported |
| Alternative option | Tested by at least one editor, meets stated requirements, no known issues | Superseded by a better option, vendor conflict, quality decline reported by multiple readers |
| Reference link | Published by an authority body (standards org, gov agency, university), publicly accessible, no paywall | Link goes dead, content is archived or removed, source loses authority status |
| Affiliate product | Same standards as core, with affiliate disclosure visible on every mention | Same withdrawal rules; affiliate relationship terminated immediately upon conflict discovery |
Footnote: This table describes our internal policy. It does not cover edge cases where a product is recommended by name without a direct retailer link, or where a recommendation includes a caveat (such as “this model has been superseded but is still available secondhand at fair prices”). Those situations are handled case-by-case and documented in the page where they appear.
