It combines the principles of the Series 3 preamplifier and monoblocks into a single unit – without compromising on performance, design, or sound. Its sophisticated design, featuring separate ground systems, high-quality transistors, and innovative components, makes it a winner for listeners seeking the highest resolution, naturalness, and a member experience without technical coloration. The A-3 acts like a window into the musical scene – detailed, vibrant, and full of spontaneity.\u003c\/p\u003e\n\n\u003chr data-start=\"761\" data-end=\"764\"\u003e\n\n\u003ch3 data-start=\"766\" data-end=\"788\"\u003e Product presentation\u003c\/h3\u003e\n\n \u003cp data-start=\"790\" data-end=\"1900\"\u003eThe \u003cstrong data-start=\"794\" data-end=\"810\"\u003eSoulnote A-3\u003c\/strong\u003e is part of the Series 3 product line and is available in two finishes: \u003cstrong data-start=\"887\" data-end=\"905\"\u003ePremium Silver\u003c\/strong\u003e and \u003cstrong data-start=\"910\" data-end=\"927\"\u003ePremium Black\u003c\/strong\u003e . The device is a real powerhouse - two 700-VA toroidal transformers supply the left and right channels separately, plus an additional transformer for control and pre-amp functions. The output power is \u003cstrong data-start=\"1169\" data-end=\"1197\"\u003e120 W per channel into 4 ohms\u003c\/strong\u003e . The A-3 uses a \u003cstrong data-start=\"1218\" data-end=\"1259\"\u003esingle-push-pull (SEPP) output stage\u003c\/strong\u003e with TO3-type transistors, similar to those used in the M-3 Series monoblocks. The pre-driver\/driver stages operate in a Darlington configuration, and all control and relay functions are electrically isolated to minimize interference. A special feature is the complete separation of the ground wire systems for the left and right channel networks, as well as the use of a newly developed non-negative feedback (non-NFB) circuit in the voltage gain stage. This technical framework gives the A-3 clarity, control, and detail to a degree rarely heard in integrated amplifiers.\u003c\/p\u003e\n\n\u003chr data-start=\"1902\" data-end=\"1905\"\u003e\n\n \u003ch3 data-start=\"1907\" data-end=\"1936\"\u003eSpecial features\u003c\/h3\u003e\n\n \u003cp data-start=\"1938\" data-end=\"2883\"\u003eThe \u003cstrong data-start=\"1942\" data-end=\"1958\"\u003eSoulnote A-3\u003c\/strong\u003e offers many outstanding features: it has three \u003cstrong data-start=\"2017\" data-end=\"2038\"\u003ebalanced (XLR)\u003c\/strong\u003e and three \u003cstrong data-start=\"2048\" data-end=\"2071\"\u003eunbalanced (RCA)\u003c\/strong\u003e inputs; one of these inputs serves as a recording in\/out with a bypass function, allowing sources to be played directly without affecting the volume control. The volume control uses resistive switching relays to prevent noise or sonic interference from electronic components. The cabinet design utilizes floating elements—the top cover and parts of the rear panel are not rigidly attached; this technology serves to minimize vibration and resonance. The heatsink is innovative: a solid copper plate acts both as a power rail for the power transistors and as a heat sink. This design reduces the need for additional wiring, and performance remains more stable under load.\u003c\/p\u003e\n\n\u003chr data-start=\"2885\" data-end=\"2888\"\u003e\n\n \u003ch3 data-start=\"2890\" data-end=\"2915\"\u003eTechnology \u0026amp; Materials\u003c\/h3\u003e\n\n\u003cp data-start=\"2917\" data-end=\"3729\"\u003e The A-3's technology is based on high-quality components and a sophisticated architecture. The \u003cstrong data-start=\"3008\" data-end=\"3045\"\u003eTO3 Metal CAN bipolar transistors\u003c\/strong\u003e in the output and driver stages ensure high current and power handling. The Darlington configuration ensures that the control voltage remains stable even at low levels and high power. The absence of negative feedback in the preamplifier (non-NFB) ensures that the signal remains direct and undistorted, and interference is minimized. Two powerful toroidal transformers (700 VA each) serve as the power supply, plus another for control functions; rectification and supply are redundant and robustly designed. This combination offers not only power but also an audible degree of calm, control, and resolution in every sound range.\u003c\/p\u003e\n\n\u003chr data-start=\"3731\" data-end=\"3734\"\u003e\n\n\u003ch3 data-start=\"3736\" data-end=\"3766\"\u003e Sustainability \u0026amp; Manufacturing\u003c\/h3\u003e\n\n \u003cp data-start=\"3768\" data-end=\"4529\"\u003eThe \u003cstrong data-start=\"3772\" data-end=\"3788\"\u003eSoulnote A-3\u003c\/strong\u003e is manufactured in Japan with high standards of craftsmanship, using materials designed for durability and performance. The craftsmanship is meticulous – heavy, rigidly machined aluminum plates, high-quality connectors, and robust mechanics demonstrate that no cheap compromises were made. The weight of over \u003cstrong data-start=\"4115\" data-end=\"4124\"\u003e30 kg\u003c\/strong\u003e ensures not only thermal stability but also low vibration sensitivity. Soulnote also places great importance on user control over many aspects – such as switchable ground connections, bypass functions, and high-quality relays.

The Series 3 components represent the current highest level of development, where technology is tested for sonic performance—not just based on measured values. The A-3 continues this philosophy: It integrates a preamp and power amplifier in a single enclosure with features otherwise found in separate, very expensive systems. The developer places particular emphasis on structural solutions such as floating panels, separate ground lines, and high-quality components that work together like the gears of a clockwork.\u003c\/p\u003e\n\n\u003chr data-start=\"6932\" data-end=\"6935\"\u003e\n\n\u003ch3 data-start=\"6937\" data-end=\"6968\"\u003e Basic knowledge (optional)\u003c\/h3\u003e\n\n\u003cp data-start=\"6970\" data-end=\"7002\"\u003e A few technical explanations:\u003c\/p\u003e\n\n \u003cp data-start=\"7004\" data-end=\"7236\"\u003e\u003cstrong data-start=\"7004\" data-end=\"7039\"\u003ePush-Pull (SEPP) output stage:\u003c\/strong\u003e This stage uses two complementary transistors, each responsible for the upper and lower parts of the signal.
