834 Integrated Amplifier By EAR

EAR proudly offers EAR Electronics, renowned for some of the most musical and engaging tube gear available. While the high-end tube amplifier market includes many brands, often at premium prices, EAR stands out for its visionary designs and exceptional sonic character, delivering a listening experience that feels truly special. With multiple models available, it’s possible to select the amplifier that best matches your system and the tonal qualities you prefer.

The EAR 834 is a push-pull stereo integrated amplifier delivering 50 watts per channel into 4, 8, or 16 ohms. It is compatible with 6L6, EL34, or KT66 output tubes, features self-biasing, and offers six line-level inputs plus a tape output, combining flexibility with the rich, dynamic sound that EAR amplifiers are known for.

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.
