It demonstrates that a preamplifier can be not only clean and technically superior, but also deeply involved in the musical experience: sober enough to deliver transparency, warm enough to prevent the musical material from being rendered like mere data. For listeners who demand timbres, stage imaging, and dynamics while simultaneously achieving great detail, the P-3 is a true touchstone—anyone who has ever used it will hear that detail, quality, and soul come together here.\u003c\/p\u003e\n\n\u003chr data-start=\"926\" data-end=\"929\"\u003e\n\n\u003ch3 data-start=\"931\" data-end=\"953\"\u003e Product presentation\u003c\/h3\u003e\n\n \u003cp data-start=\"955\" data-end=\"1648\"\u003eThe \u003cstrong data-start=\"959\" data-end=\"975\"\u003eSoulnote P-3\u003c\/strong\u003e is a high-end line preamplifier that makes no compromises.

For example, Soulnote uses \u003cstrong data-start=\"1841\" data-end=\"1867\"\u003enaked foil resistors\u003c\/strong\u003e , a special type of very high-quality foil resistor without additional resin or potting compounds, in order to keep distortion and temperature sensitivity to a minimum. There is a \u003cstrong data-start=\"2051\" data-end=\"2103\"\u003eself-developed relay switch type (RSR-2-12D)\u003c\/strong\u003e that is used both as an input selector and for volume control - high quality, with low contact damping, precise and durable. The P-3 is constructed as a completely separate mono unit (twin mono), and the housing and internal elements are designed to minimize vibrations and resonances as much as possible. Also integrated is a switch to avoid GND loops (“ground loops”) - both the signal and ground connection can be switched so that inactive sources do not affect the sound.\u003c\/p\u003e\n\n\u003chr data-start=\"2691\" data-end=\"2694\"\u003e\n\n \u003ch3 data-start=\"2696\" data-end=\"2721\"\u003eTechnology \u0026amp; Materials\u003c\/h3\u003e\n\n \u003cp data-start=\"2723\" data-end=\"3628\"\u003eThe internal technology of the \u003cstrong data-start=\"2746\" data-end=\"2753\"\u003eP-3\u003c\/strong\u003e contains everything that makes Soulnote a top brand: The output stage uses \u003cstrong data-start=\"2837\" data-end=\"2929\"\u003ea balanced Type-R circuit without negative feedback (non-feedback balanced circuit)\u003c\/strong\u003e , which ensures a very clean, undistorted output signal. The volume is controlled via a \u003cstrong data-start=\"3033\" data-end=\"3056\"\u003erelay switching system\u003c\/strong\u003e with typically 144 steps in approximately 0.5 dB increments, meaning volume changes occur with almost no audible transition. The construction is designed to preserve detail even at lower volumes. The transformers are generously dimensioned, and the layout was conceived to ensure short paths and a stable, interference-free power supply. Mechanically, the P-3 also relies on high-quality materials, rigid aluminum housing elements, and solid cooling structures that ensure thermal stability and reduced self-resonance.\u003c\/p\u003e\n\n\u003chr data-start=\"3630\" data-end=\"3633\"\u003e\n\n \u003ch3 data-start=\"3635\" data-end=\"3665\"\u003eSustainability \u0026amp; Manufacturing\u003c\/h3\u003e\n\n\u003cp data-start=\"3667\" data-end=\"4228\"\u003e The \u003cstrong data-start=\"3671\" data-end=\"3687\"\u003eSoulnote P-3\u003c\/strong\u003e is built in Japan with a high level of vertical integration and great care. Every component is carefully tested, and the housing and switches\/parts exposed to potential stress are dimensioned for longevity. The design emphasizes repairability and component quality – this is evident in the relays, resistors, and the power and voltage supply. The design of the housing and heatsinks also indicates a long service life where neither component fatigue nor cost-cutting measures will compromise the sound quality.\u003c\/p\u003e\n\n\u003chr data-start=\"4230\" data-end=\"4233\"\u003e\n\n\u003ch3 data-start=\"4235\" data-end=\"4263\"\u003e Technical data (specs)\u003c\/h3\u003e\n\n\u003cp data-start=\"4265\" data-end=\"4879\"\u003e \u003cstrong data-start=\"4265\" data-end=\"4278\"\u003eInputs:\u003c\/strong\u003e 4 x XLR (balanced), 4 x RCA \/ RCA (single-ended)\u003cbr data-start=\"4329\" data-end=\"4332\"\u003e \u003cstrong data-start=\"4332\" data-end=\"4345\"\u003eOutputs:\u003c\/strong\u003e 3 x XLR (balanced), 1 x Cinch\/RCA (switchable or deactivated)\u003cbr data-start=\"4410\" data-end=\"4413\"\u003e \u003cstrong data-start=\"4413\" data-end=\"4443\"\u003eMaximum output voltage:\u003c\/strong\u003e 21 Vrms \u003cbr data-start=\"4451\" data-end=\"4454\"\u003e\u003cstrong data-start=\"4454\" data-end=\"4473\"\u003eMaximum gain:\u003c\/strong\u003e 11 dB\u003cbr data-start=\"4479\" data-end=\"4482\"\u003e \u003cstrong data-start=\"4482\" data-end=\"4499\"\u003eFrequency response:\u003c\/strong\u003e approx. 2 Hz – 1 MHz (±3 dB)\u003cbr data-start=\"4524\" data-end=\"4527\"\u003e \u003cstrong data-start=\"4527\" data-end=\"4558\"\u003eTotal harmonic distortion (THD):\u003c\/strong\u003e about 0.0015% at 1.5 Vrms\u003cbr data-start=\"4585\" data-end=\"4588\"\u003e \u003cstrong data-start=\"4588\" data-end=\"4622\"\u003eResidual noise:\u003c\/strong\u003e approx. 13 µV (at 20 kHz low pass)\u003cbr data-start=\"4654\" data-end=\"4657\"\u003e \u003cstrong data-start=\"4657\" data-end=\"4678\"\u003eOutput impedance:\u003c\/strong\u003e 6.8 ohms\u003cbr data-start=\"4686\" data-end=\"4689\"\u003e \u003cstrong data-start=\"4689\" data-end=\"4711\"\u003ePower consumption:\u003c\/strong\u003e about 20 W in operation\u003cbr data-start=\"4732\" data-end=\"4735\"\u003e \u003cstrong data-start=\"4735\" data-end=\"4751\"\u003eDimensions:\u003c\/strong\u003e approx. 454 × 174 × 430 mm (W × H × D)\u003cbr data-start=\"4786\" data-end=\"4789\"\u003e \u003cstrong data-start=\"4789\" data-end=\"4801\"\u003eWeight:\u003c\/strong\u003e approx. 25 kg\u003cbr data-start=\"4811\" data-end=\"4814\"\u003e \u003cstrong data-start=\"4814\" data-end=\"4831\"\u003eScope of delivery:\u003c\/strong\u003e remote control, power cable, spike board, spikes\u003c\/p\u003e\n\n\u003chr data-start=\"4881\" data-end=\"4884\"\u003e\n\n\u003ch3 data-start=\"4886\" data-end=\"4919\"\u003e Test reports \/ press reviews\u003c\/h3\u003e\n\n \u003cp data-start=\"4921\" data-end=\"5465\"\u003eThere are German articles, for example, in \u003cstrong data-start=\"4956\" data-end=\"4973\"\u003eHiFiStatement\u003c\/strong\u003e , praising the P-3 as a preamplifier that offers an exceptionally homogenous sound.
