The cabinet is massive, with external dimensions of approximately 340 × 251 × 512 millimeters and a weight of approximately 31 kilograms per unit. Each monoblock has a single push-pull output stage, designed with a four-stage Darlington structure, and uses industrial-grade “can-type” power transistors. The M-3 offers an output power of \u003cstrong data-start=\"1297\" data-end=\"1318\"\u003e160 watts into 4 ohms\u003c\/strong\u003e , combined with a very wide frequency response of \u003cstrong data-start=\"1366\" data-end=\"1394\"\u003e2 Hz to 200 kHz (±1 dB)\u003c\/strong\u003e .

The power transistors in metal housings (TO-3 or \"can type\") offer robust mechanical mounting and optimal heat dissipation. The Darlington output ensures high current reserves and stability even at low impedances. The layout minimizes signal paths, and the use of copper busbars reduces resistance and inductive losses. The filter stages and rectifiers are dimensioned to handle both power requirements and fast pulses. Each monoblock is tuned for power and control without compromising sonic naturalness.\u003c\/p\u003e\n\n\u003chr data-start=\"3558\" data-end=\"3561\"\u003e\n\n\u003ch3 data-start=\"3563\" data-end=\"3593\"\u003e Sustainability \u0026amp; Manufacturing\u003c\/h3\u003e\n\n \u003cp data-start=\"3595\" data-end=\"4131\"\u003eThe \u003cstrong data-start=\"3599\" data-end=\"3615\"\u003eSoulnote M-3\u003c\/strong\u003e is handcrafted in Japan with a high level of vertical integration. The choice of materials, dimensions, and components are designed for durability: solid heat sinks, sturdy terminal fittings, high-quality relays, and precise rectifier components. The weight and construction contribute to the device's thermal and mechanical stability, even during long listening sessions. Furthermore, spare parts supply and service are part of Soulnote's philosophy – the M-3 is not a quickly replaceable consumer device, but an investment.\u003c\/p\u003e\n\n\u003chr data-start=\"4133\" data-end=\"4136\"\u003e\n\n\u003ch3 data-start=\"4138\" data-end=\"4166\"\u003e Technical data (specs)\u003c\/h3\u003e\n\n\u003cp data-start=\"4168\" data-end=\"4704\"\u003e \u003cstrong data-start=\"4168\" data-end=\"4179\"\u003eSystem:\u003c\/strong\u003e Monoblock power amplifier\u003cbr data-start=\"4198\" data-end=\"4201\"\u003e \u003cstrong data-start=\"4201\" data-end=\"4222\"\u003eOutput power:\u003c\/strong\u003e 160 W at 4 Ω\u003cbr data-start=\"4235\" data-end=\"4238\"\u003e \u003cstrong data-start=\"4238\" data-end=\"4255\"\u003eFrequency response:\u003c\/strong\u003e 2 Hz – 200 kHz (±1 dB)\u003cbr data-start=\"4278\" data-end=\"4281\"\u003e \u003cstrong data-start=\"4281\" data-end=\"4330\"\u003eInput sensitivity \/ input resistance:\u003c\/strong\u003e 1 V \/ 25 kΩ \u003cbr data-start=\"4342\" data-end=\"4345\"\u003e\u003cstrong data-start=\"4345\" data-end=\"4368\"\u003eGain:\u003c\/strong\u003e 22 dB\u003cbr data-start=\"4374\" data-end=\"4377\"\u003e \u003cstrong data-start=\"4377\" data-end=\"4405\"\u003eTotal Harmonic Distortion (THD):\u003c\/strong\u003e 0.1% at 1W\u003cbr data-start=\"4419\" data-end=\"4422\"\u003e \u003cstrong data-start=\"4422\" data-end=\"4443\"\u003eOperating voltage:\u003c\/strong\u003e 230 V AC \/ 50 Hz\u003cbr data-start=\"4460\" data-end=\"4463\"\u003e \u003cstrong data-start=\"4463\" data-end=\"4485\"\u003ePower consumption:\u003c\/strong\u003e approx. 110 W\u003cbr data-start=\"4495\" data-end=\"4498\"\u003e \u003cstrong data-start=\"4498\" data-end=\"4514\"\u003eDimensions:\u003c\/strong\u003e approx. 340 × 251 × 512 mm (W × H × D)\u003cbr data-start=\"4549\" data-end=\"4552\"\u003e \u003cstrong data-start=\"4552\" data-end=\"4564\"\u003eWeight:\u003c\/strong\u003e approx. 31 kg\u003cbr data-start=\"4574\" data-end=\"4577\"\u003e \u003cstrong data-start=\"4577\" data-end=\"4597\"\u003eFinish variants:\u003c\/strong\u003e Premium Silver \/ Premium Black\u003cbr data-start=\"4628\" data-end=\"4631\"\u003e \u003cstrong data-start=\"4631\" data-end=\"4648\"\u003eScope of delivery:\u003c\/strong\u003e speaker cable, rack feet \/ spikes, power cable\u003c\/p\u003e\n\n\u003chr data-start=\"4706\" data-end=\"4709\"\u003e\n\n\u003ch3 data-start=\"4711\" data-end=\"4744\"\u003e Test reports \/ press reviews\u003c\/h3\u003e\n\n\u003cp data-start=\"4746\" data-end=\"4886\"\u003e A German-language expert review is not yet available.
