It’s the first release from ARC’s new solid-state engineering team, built around a fully balanced architecture that blends high-current dynamics with tonal control and clarity. From the first note, the S-100 reveals nuance and weight with an effortlessness that defies its understated form. This isn’t just a new model. It’s the start of a new era in ARC’s power amplifier lineage.\u003c\/p\u003e\n\u003ch5\u003eAudio Research S-100 Key Features\u003c\/h5\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eRated Power:\u003c\/strong\u003e 100 WPC into 8 ohms, 200 WPC into 4 ohms\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSignal Path:\u003c\/strong\u003e Differential JFET input stage, bipolar transistor voltage and output stages\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTopology:\u003c\/strong\u003e Fully balanced from input to output\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInput Select:\u003c\/strong\u003e Rear-panel switchable between balanced XLR and single-ended RCA\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChassis:\u003c\/strong\u003e New low-profile case with custom-machined heatsinks\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDesign Philosophy:\u003c\/strong\u003e Solid-state architecture voiced for ARC’s classic musicality\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturing:\u003c\/strong\u003e Hand-built in Minnesota, USA\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch5\u003eSolid-State Power, ARC Soul\u003c\/h5\u003e\n\u003cp\u003eAt its heart, the S-100 is a fully analog design that prioritizes low distortion, wide bandwidth, and dynamic agility. The front end starts with a differential JFET input stage for excellent linearity and noise rejection. From there, the signal flows through bipolar voltage and output stages operating in Class AB, delivering grip and tonal authority across a wide range of speakers. The result is power with finesse—never sterile, always musical.\u003c\/p\u003e\n\u003ch5\u003eBalanced from Input to Output\u003c\/h5\u003e\n\u003cp\u003eThe S-100’s fully balanced topology helps eliminate interference, lower distortion, and preserve signal integrity from source to speaker. A rear-panel selector lets you switch between balanced XLR and single-ended RCA inputs depending on your system. Internally, the circuit remains symmetrical, maintaining coherence regardless of input type. For listeners who demand both flexibility and fidelity, this architecture offers the best of both worlds.\u003c\/p\u003e\n\u003ch5\u003eDesigned for the Next Chapter\u003c\/h5\u003e\n\u003cp\u003eThe S-100 debuts a new Audio Research chassis design with custom-machined heatsinks, a low-profile silhouette, and subtle industrial refinement. It’s built by hand at ARC’s Minnesota facility alongside the rest of the Reference and Foundation Series. The S-100 is part of a new generation of ARC components launching in 2025 to mark the company’s 55th anniversary, and it’s a clear sign that the future is every bit as exciting as the past.
