861 Power Amplifier By EAR

We’re excited to present EAR electronics, renowned for producing some of the most musical and refined tube amplifiers on the market. In the world of high-end tube audio, countless brands claim to offer top-tier performance, with many carrying much higher price tags than EAR. However, at Jaguar, we focus exclusively on amplifiers from visionary designers like EAR and Lamm, whose creations stand head and shoulders above the rest, offering unparalleled sound and craftsmanship.

With a variety of models to choose from, you can find the perfect EAR amplifier to match your system and bring your desired sound character to life.

The EAR 861 is a pure Class A push-pull power amplifier that operates in enhanced triode mode, delivering 32 watts per channel in stereo (and 64 watts in mono when bridged). It effortlessly drives 4, 8, or 16 ohm speakers with zero overall negative feedback, ensuring incredibly clean and natural sound reproduction. Featuring EL519 output tubes, a self-biasing design, and both balanced and unbalanced inputs, the 861 offers audiophiles a true high-performance solution for ultimate listening enjoyment.

EAR (formerly “Esoteric Audio Research”) is the brainchild of Tim de Paravicini, whose name has been associated since the 1970s with electronics of the highest fidelity. De Paravicini’s innovative techniques have not only borne fruit in products for EAR, but in designs for some of the world’s most highly regarded electronics manufacturers. Some of these designs have been continually prized—and sought—by discerning listeners for decades after their introduction.

Tim de Paravicini has also made unique contributions to the world of professional recording and mastering. Users of his tape recording systems, microphones, and other recording technology include performers Pink Floyd and Lenny Kravitz, the Altarus and Water Lily record labels, and renowned recording and mastering engineers like Robert Ludwig, Joe Gastwirt, and James Guthrie. One of the world’s highest-ranked mastering facilities, The Exchange in London, uses two playback systems in which the entire chain–from tape machines and equalizers to cutter amplifiers and monitoring equipment—is EAR-designed and built. Mobile Fidelity Sound Labs uses his LP cutting system, as well as a playback tape deck with his electronics.

EAR amplifiers are unequaled in their ability to deliver a pure rendition of the signal fed into them, free from the colorations and distortions of most amplifiers. Tim de Paravicini has been instrumental in investigating the role of ultrasonic resonances in amplifier circuits and their effect on transient response. He has also undertaken significant original research on the subjective effects of distortion. This research has not only facilitated the interpretation of amplifier measurements but has shed light on the correlation between measurements and sound quality. The results are easy to appreciate—EAR amplifiers are among the most accurate amplifiers ever made.
