Jaguar is pleased to offer EAR electronics, some of the most musical tube gear in existence. When it comes to high-end tube amplifiers, there are hundreds of brands on the market, many costing much more than EAR. However, at Jaguar we’re only interested in amps like EAR or Lamm, which are created by visionary designers and stand above the others as truly unique and special. Numerous available models allow you to select one that’s the best match for your system and the sound character you’re going for.

The EAR 890 is a Push-pull power amplifier that outputs 70 Watts per channel stereo (bridgeable to 140 watts mono) into 4, 8, or 16 ohms. It uses KT90 output tubes, is self-biasing and is capable of balanced and unbalanced operation.


“All in all, this is a great amplifier! It is extremely easy to set up and sounds good with little or no tweaking. It is about enjoying the music and not a finicky or touchy piece of gear. It is very cohesive and the tonality is excellent and very well integrated from highs to lows.”


About EAR

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.

  1. Andrew Harris

    “Even the inevitable transfer noise, though still audible, imparted less distraction and fussiness to the listening experience.”


  2. Rajendra Rehman Thaman

    “I not only recommend it, I’m buying the review sample to prove to my Positive Feedback friends that I stand behind my reviews! I highly recommend the EAR 890 Power Amplifier. It is class A+ in my audiophile domain, and my new tube reference.”


  3. Yogesh Handa

    “the more I listened, the more its general even handedness and superb midrange eventually worked on me an alluringly sensuous magic. I realized I was absolutely enjoying the music, swept along in both the thrill and the repose of its finer tones.”
