{"type":"firestarter.listing","listing":{"id":"lst_1JxdJ2p_","product_name":"TOPPING Mini 300 Compact Power Desk Amplifier","category":"Headphone DAC/Amp","description":" \nA fully-balanced Class-D amplifier that fits anywhere\nA compact power amplifier that blends precision, power, and balance. The TOPPING Mini 300 delivers 140 watts per channel into 4Ω with astonishingly low distortion—less than 0.0005% THD+N at 8Ω, 5W output. Its fully-balanced Class-D architecture ensures an exceptionally clean signal path, while its quiet 124dB SNR keeps the background utterly black. Whether driving bookshelf speakers in your office or powering monitors on your desk, the Mini 300 brings clarity, composure, and control to every listening session.\n\nPower that fits anywhere\n\nThe Mini 300 is built for people who want serious power without surrendering their workspace. At just 6.5\" wide, it slips easily into desktop rigs or nearfield listening stations. Don’t let the small size fool you—this amp pushes 140W × 2 into 4Ω, plenty to drive demanding passive speakers with headroom to spare. Its all-aluminum chassis not only looks refined but also doubles as a heat sink, with bottom and side vents that quietly manage thermals while you enjoy long listening sessions.\n\nBalanced architecture, balanced sound\n\nInside, the Mini 300 runs a fully-balanced Class-D circuit. That means each channel has its own complete amplification path, eliminating crosstalk and rejecting external noise before it ever touches your speakers. The result is an ultra-quiet floor—124dB SNR and less than 15μVrms of noise—so the only thing you’ll hear is the music itself. Smooth, transparent, and effortlessly controlled.\n\nPrecision that’s audible\n\nMeasurements don’t make music, but they help explain why the Mini 300 sounds so composed. At 5W into 8Ω, total harmonic distortion plus noise measures below 0.0004%. That’s vanishingly low, translating to clean transients, stable imaging, and lifelike dynamics even at low volumes.\n\nAuto-on convenience\n\nThe 12V trigger input lets the Mini 300 power on and off in sync with your DAC or preamp—no reaching behind your stack or fumbling for switches.
