Disclosure & Funding

SoundPath Lab exists to help readers make better audio decisions through clear, practical, independently judged information. The publication is operated by FASTHiFi Technology Co., Limited, a company registered in Hong Kong.

OWNERSHIP AND OPERATIONAL SEPARATION

SoundPath Lab operates independently from retailers and marketplaces. Retail inventory, margins, seller priorities or sales activity do not determine what SoundPath Lab covers, recommends or criticizes.

Under the policy effective 24 October 2026, SoundPath Lab has no current brand agency, distribution or promotional partnership relationships. Each author, editor and contributor must separately declare relevant current and historical interests before editing, scoring or reviewing a product. A declared or unresolved conflict requires editorial review, disclosure and, where appropriate, recusal; it cannot purchase a rating, recommendation, issue removal or conclusion.

EDITORIAL INDEPENDENCE

Our conclusions are based on evidence, repeatable use and editorial judgment. Manufacturers, distributors, retailers and advertisers cannot approve, rewrite, suppress or purchase a conclusion. We report strengths and limitations, including compatibility, software behavior, usability, reliability, ownership risk and value—not only sound quality.

COVERAGE AND PRODUCT SELECTION

SoundPath Lab is built for users, not for a retailer's catalogue. Brands and products are selected because they answer real reader questions, represent important alternatives, introduce relevant technology, reveal ownership risks or improve a category comparison. Coverage is not limited to products sold by any retailer or company connected to a contributor. A product can be included even when no purchase link is available.

HOW PRODUCTS ARE SOURCED

From 24 October 2026, new SPL review tests use independently purchased units, with the purchase source recorded for each unit. Historical supplied, loaned, discounted or industry-access units retain their original source disclosures and test dates. Any unverified historical acquisition remains explicitly pending, and a documented product profile is never relabeled as a self-purchased or independently measured review without supporting records. Manufacturer documents, owner reports, SPL functional tests and SPL instrument measurements remain separate evidence types, each limited to its recorded scope.

SELLER LINKS AND PLACEMENT

The only link shown directly in a buying component is the manufacturer's official product-information page, used as a reference source rather than a purchase endorsement. Amazon, EMiUZEK, official brand stores, marketplaces and all other transaction links appear under More sellers. Their order follows reader region, authorized status, warranty clarity, returns and availability—not commission or retailer profit. Every seller has zero editorial weight.

AFFILIATE LINKS

Under the policy effective 24 October 2026, SoundPath Lab does not enter new affiliate arrangements or accept commissions for product coverage, placement, rankings or conclusions. Historical affiliate relationships, if any, remain disclosed on the affected records with their original dates. Any remaining commission-bearing links must be removed from current buying components or retained only in clearly labeled historical records after editorial review.

ADVERTISING AND SPONSORSHIP

From 24 October 2026, SoundPath Lab does not accept brand-sponsored reviews or paid product placement. Previously sponsored or supplied content retains its original disclosure and is not relabeled as independent testing. No advertiser or sponsor may approve, suppress or purchase editorial conclusions or the removal of substantiated limitations.

PRICING AND AVAILABILITY

Prices, firmware features, service support, regional availability and compatibility can change. Readers should verify critical details before purchase. Meaningful errors and changes are corrected, dated and retained in the public record where appropriate.

READER TRUST

The long-term value of SoundPath Lab depends on serving a broad audio audience rather than a single store, brand or existing product pool. Funding supports research, testing, photography, measurement, hosting and editorial work without turning the publication into a storefront.

Current independence policy effective: 24 October 2026. This policy revision does not change original publication dates, historical source disclosures or test dates.
