Why 85?
A weighted aggregate of four category scores. Reasoning is editorial — physics-grounded engine in development.
JDS Labs Atom Amp 2 drives 300 Ω loads cleanly within its rated output. HD 600 is a benchmark headphone for amp matching; the Atom is documented as transparent above the noise floor at typical listening levels.
WiiM Ultra outputs analog RCA into the Atom — an honest line-out path with the Ultra's onboard ESS DAC. Streaming protocol coverage spans Tidal Connect / Roon / Spotify Connect. No digital re-clocking needed since the chain is single-conversion.
Headphones bypass room acoustics entirely. The 'room match' category here reflects desk ergonomics rather than acoustic loading — small office with the listener in a comfortable seated position.
HD 600 is a reference-neutral headphone with a documented measured response close to the Harman over-ear target. Atom amp adds nothing audible. WiiM's DAC has been measured at low THD across the audioband.
