Specs first. Measurements when available. Caveats always.
Every spec is colored by where it came from and whether anyone independent confirmed it. A wash of gold means "manufacturer’s word only"; green and blue mark numbers a lab stands behind.
Self-check: only 1% of populated spec cells are actually checked so far. Review sites, please keep going; the spreadsheet is hungry and press releases are not a food group.

The manufacturer’s number, and an independent measurement agrees.
The manufacturer’s number. Nobody independent has checked it.
The value comes from an independent lab/review; the maker was silent.
Vendor claim and independent measurement disagree beyond that field’s tolerance.
The cell needs context: either a claim conflicts with measurement, or the raw value was normalized for comparison.
Heaviest, priciest, the cheapest way into Atmos, the measurably-quietest — auto-derived leaderboards, each a plain sort over the data, labelled by what we actually have.
Speakers
Full-range tower loudspeakers.
Bookshelf / stand-mount loudspeakers.
Center-channel loudspeakers.
Atmos elevation / height-channel speakers (up-firing or dedicated).
Slim on-wall loudspeakers.
Architectural in-wall and in-ceiling loudspeakers.
Subwoofers — powered (most) and passive.
Bluetooth speakers — the professional kind. Powered PA cabinets that happen to pair with your phone. Sorted by SPL, because that is the spec that matters. No plastic eggs.
Amplifiers
Stereo, monoblock and multichannel power amplifiers.
Preamp + power amp in one chassis; some add a DAC, phono stage, or streaming.
Line-level preamplifiers.
Standalone phono stages (MM/MC).
Standalone audio power supplies, DC adapters, motor controllers and PSU upgrade chassis.
Headphone amplifiers and DAC/amps — drive capability into common loads.
Headphones and in-ear monitors — driver type, acoustic design, impedance, sensitivity, fit and connection facts.
Furniture-style all-in-one music systems: cabinet, amplification, speakers, sources, and record storage as one object.
External DSP, speaker-management, active-crossover and bass-management processors for multichannel or multiway systems.
Home Theater
Two-channel receivers (integrated amp + tuner, often with DAC/streaming).
Multichannel home-theater receivers (amplification + surround processing).
Surround-sound preamplifier-processors (no power amplification).
Current-production home-theater TVs only: Dolby Vision and HDR10+ support are both required.
Current-production home-theater projectors only: Dolby Vision and HDR10+ support are both required.
Sources
Analog
Record players / turntables (manual and automatic).
Tonearms — geometry and effective mass for cartridge matching.
Phono cartridges — the matching figures a phono stage and tonearm need.
Compact cassette decks — playback and record/playback. Current production only; vintage Nakamichi/etc. belong in a later archive.
Reel-to-reel / open-reel tape machines. Current production only; classic Studer/Revox/etc. belong in a later archive.
Standalone AM/FM/DAB/HD/internet radio tuners sold as source components — not tuners bundled inside a receiver.
Digital audio
Digital-to-analog converters. Input/output columns are connector counts (number of each jack).
Network streamers, digital transports, streaming DACs and streaming preamps. No structured comparison source exists for these anywhere — this schema is the first.
CD, SACD and disc players / transports.
Video
Game consoles as AV sources and historical machines — native output paths, video/audio capability, and the hardware facts that give each generation its character.
Media streamers (Apple TV, Shield, Roku…) — resolution, HDR, and the Dolby/DTS passthrough limits that bite ripped-disc playback.
4K UHD Blu-ray players — disc formats, HDR, lossless audio bitstreaming, and analog output.
