It delivers 140W per channel into 4Ω with astonishingly low distortion – less than 0.0005% THD+N at 8Ω\/5W – and a quiet 124dB SNR that 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.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFully Balanced Class-D Architecture\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe Mini 300 runs a fully balanced Class-D circuit in which each channel has its own complete amplification path, eliminating crosstalk and rejecting external noise before it touches your speakers. The result is an ultra-quiet floor – 124dB SNR and less than 15µVrms of noise – so the only thing you hear is the music itself.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003ePower That Fits Anywhere\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eAt just 6.5 inches wide, the Mini 300 slips easily into desktop rigs or nearfield listening stations. Despite the small size, it pushes 140W x 2 into 4Ω, plenty to drive demanding passive speakers with headroom to spare.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003ePrecision That Is Audible\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eAt 5W into 8Ω, total harmonic distortion plus noise measures below 0.0004% – vanishingly low, translating to clean transients, stable imaging, and lifelike dynamics even at low volumes.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eAuto-On Convenience with 12V Trigger\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe 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. Once connected, it wakes up and shuts down with your system.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDual Inputs: Balanced and Unbalanced\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe rear panel accepts both balanced TRS and unbalanced RCA inputs, no adapters needed. Balanced inputs offer better rejection of interference for longer cable runs, while RCA keeps compatibility with everyday sources. Flip the front switch between BAL and SE to match your source.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eSafe, Silent, Reliable\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003ePower on and off are handled quietly, with protection circuitry guarding against overcurrent and overheating. The all-aluminum chassis not only looks refined but also doubles as a heat sink, with bottom and side vents that quietly manage thermals during long listening
