The company's new flagship combines headphone amplification, speaker amplification, and preamplifier functionality in a single component. Featuring a pair of 300B power tubes driven by CV181 (6SN7) tubes, the Eos is designed to deliver the warmth and musicality associated with triode amplification while offering the power, low noise, and versatility needed for a wide range of listening systems.\u003c\/p\u003e\n\n\u003cp\u003eThe Eos is the first Feliks Audio amplifier capable of driving both headphones and loudspeakers. Its headphone outputs deliver up to 8 W, while its speaker outputs provide up to 6 W for suitably efficient loudspeakers. Despite this substantial output, the Eos is also designed to accommodate sensitive headphones and IEMs with impedances as low as 10 ohms. RCA and balanced XLR preamp outputs extend its versatility, allowing the Eos to serve as the centerpiece of a larger audio system.\u003c\/p\u003e\n\n\u003cp\u003eFeliks Audio has also equipped the Eos with a display, integrated diagnostics, and remote operation. Listeners can monitor operating conditions and tube health, adjust gain, change inputs, and switch between headphones and speakers without disconnecting either. Oak and American Walnut finishes complement the amplifier's substantial chassis and traditional tube architecture.\u003c\/p\u003e\n\n\u003ch4\u003e300B Power With Exceptional Versatility\u003c\/h4\u003e\n\u003cp\u003eAt the heart of the Eos are two 300B power tubes paired with two CV181 (6SN7) driver tubes. The 300B is celebrated for its expressive midrange, natural tonal character, and ability to communicate musical dynamics. In the Eos, this classic tube combination is implemented in a design that delivers 5 W of headphone power at 1% THD, rising to a maximum of 8 W at 5% THD. Speaker output is rated at 4 W at 1% THD, with a maximum of 6 W at 5% THD.\u003c\/p\u003e\n\n\u003cp\u003eThe Eos is equally concerned with finesse. Feliks Audio reports that the amplifier achieves the lowest distortion and widest frequency range in its product lineup. A low output impedance and carefully controlled noise levels make it suitable not only for demanding full-size headphones but also for sensitive designs and IEMs. Its preamplifier section also benefits from improvements in frequency response and noise performance compared with previous Feliks Audio models.\u003c\/p\u003e\n\n\u003ch4\u003eIntelligent Monitoring and Convenient Control\u003c\/h4\u003e\n\u003cp\u003eThe Eos introduces a comprehensive monitoring system designed to make owning a high-performance tube amplifier easier. Its integrated display provides information about the selected input, output, and gain settings, along with a VU meter. A diagnostic function allows owners to check operating voltages, temperature, and tube health, providing useful information about the amplifier's condition.\u003c\/p\u003e\n\n\u003cp\u003ePhysical controls and an included remote provide access to input selection, gain settings, display customization, and volume adjustment. A motorized volume control allows listening levels to be changed from the listening position. Headphones and speakers can remain connected simultaneously, with switching handled through the amplifier's controls.\u003c\/p\u003e\n\n\u003ch4\u003eFlexible System Integration\u003c\/h4\u003e\n\u003cp\u003eTwo unbalanced RCA inputs and one balanced XLR input accommodate a range of analog sources. Headphones connect through either a 6.3 mm jack or a 4-pin XLR connector, while dedicated speaker terminals allow the Eos to power a pair of suitably efficient loudspeakers. For larger systems, RCA and XLR preamp outputs allow connection to an external power amplifier or compatible active loudspeakers.\u003c\/p\u003e\n\n\u003ch3\u003eIncluded Accessories\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e2 × 300B power tubes\u003c\/li\u003e\n\u003cli\u003e2 × CV181 (6SN7) driver tubes\u003c\/li\u003e\n\u003cli\u003eRemote control with batteries\u003c\/li\u003e\n\u003cli\u003eAC power cord\u003c\/li\u003e\n\u003cli\u003eUser manual\u003c\/li\u003e\n\u003cli\u003eWarranty card\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eAmplifier Type:\u003c\/strong\u003e Tube headphone, speaker, and preamplifier\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003ePower Tubes:\u003c\/strong\u003e 2 × 300B\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDriver Tubes:\u003c\/strong\u003e 2 × CV181 (6SN7)\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eHeadphone Power Output:\u003c\/strong\u003e 5 W at 1% THD; maximum 8 W at 5% THD\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eSpeaker Power Output:\u003c\/strong\u003e 4 W at 1% THD; maximum 6 W at 5% THD\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eSupported Headphone Impedance:\u003c\/strong\u003e As low as 10 Ω\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eAnalog Inputs:\u003c\/strong\u003e 2 × stereo RCA, 1 × balanced XLR\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eInput Sensitivity:\u003c\/strong\u003e 1 V RMS\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eInput Impedance (RCA):\u003c\/strong\u003e 43 kΩ\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eInput Impedance (XLR):\u003c\/strong\u003e 41 kΩ\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eHeadphone Outputs:\u003c\/strong\u003e 6.3 mm, 4-pin XLR\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eSpeaker Outputs:\u003c\/strong\u003e Stereo speaker terminals\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003ePreamplifier Outputs:\u003c\/strong\u003e 1 × stereo RCA, 1 × balanced XLR\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003ePreamp Output Impedance:\u003c\/strong\u003e 1.4 Ω at 1 kHz\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDisplay:\u003c\/strong\u003e Input, output, and gain settings; VU meter; diagnostic information\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDiagnostics:\u003c\/strong\u003e Operating voltage, temperature, and tube health monitoring\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eVolume Control:\u003c\/strong\u003e Motorized, with remote operation\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eAC Power:\u003c\/strong\u003e 115 V or 230 V (±5%), 50\/60 Hz, depending on version\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFinishes:\u003c\/strong\u003e Oak, American Walnut\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDimensions (W × H × D):\u003c\/strong\u003e 18.5\" × 11.6\" × 18.5\" (470 × 295 × 470 mm)\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWeight:\u003c\/strong\u003e 57.3 lb.
