The Hifi Match is a hi-fi compatibility engine: it checks whether the components of an audio system work together and what they actually deliver in a real room. It runs entirely in the browser, with no accounts and no payments.
Every result is split into two layers, always declared. The physics layer has a formula, a threshold, a data source, and a confidence level — it's falsifiable, and that's what makes it defensible: a threshold can be argued with evidence. The editorial-criteria layer is preferences the site declares as such (for example, how several severities get grouped into one verdict), and it's never mixed visually with the physics.
The engine evaluates power margin against the room's peaks, the load and impedance the amplifier sees, impedance bridging and volume headroom when a streamer or DAC is added, the room's axial modes, and the estimated reverberation time (RT60). A missing spec is never shown as passing: it's marked "no data," and the reason is stated.
The engine never issues judgments about tonal character, predictions of sonic synergy between brands, or quality comparisons between products — that isn't calculated, and there's no plan to make it. The final listening call stays with each person; the site provides the data and the physical mechanism behind each one.
It's built for anyone assembling or reviewing an audio system who wants a physics-based check before making a purchase.
