Repair technicians see what’s actually inside every speaker and receiver that comes through their shop. This handbook writes down what they’ve been telling each other for years.
Parts 01–05 are in every edition. The Buyer’s Toolkit and Reference section come with the $49 and $99 editions. The two bonus parts are exclusive to the $99 Complete Archive.
Yes. The handbook isn't just a list — it teaches the underlying checks (ownership history, real wattage specs, the chassis test) so you can evaluate any brand, listed or not, using the same method.
Most readers apply it on their very next purchase — the savings table and checklists are built for a five-minute lookup before you buy, not a long study session.
The buy lists give you specific starting points at every budget, from a $350 bookshelf pair to a full receiver system — no prior knowledge assumed.
Almost certainly — the ownership-history angle and the real vs. advertised wattage data aren't things most enthusiasts have seen laid out this directly, even after years in the hobby.
Each edition is a PDF (23 to 67 pages depending on which you choose), delivered as an instant download the moment your payment clears — works on any device, no app required.
7-day money-back guarantee, no questions asked. If it doesn't save you at least one bad purchase, email us for a full refund.
