“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.”

EAR Yoshino (formerly Esoteric Audio Research) was founded by legendary designer Tim de Paravicini, whose name has been synonymous with high-fidelity electronics since the 1970s. His groundbreaking circuit designs have shaped not only EAR components, but also products for many of the world’s most respected audio manufacturers. Several of his creations remain highly sought after decades after their introduction — a testament to their enduring performance and musical integrity.

Beyond the world of home audio, Tim de Paravicini made significant contributions to professional recording and mastering. His tape machines, microphones, and electronics have been used by artists such as Pink Floyd and Lenny Kravitz, as well as acclaimed labels including Water Lily Acoustics. Renowned engineers like Robert Ludwig, Joe Gastwirt, and James Guthrie have relied on his designs. London’s prestigious The Exchange employs complete playback chains built around EAR electronics, while Mobile Fidelity Sound Lab has utilized his LP cutting and tape playback systems.

EAR amplifiers are celebrated for their ability to reproduce music with exceptional purity and accuracy, conveying the original signal with remarkable transparency. Tim de Paravicini’s pioneering research into ultrasonic resonances, transient response, and the subjective perception of distortion helped bridge the gap between technical measurements and real-world listening experience.

The result is amplification widely regarded by enthusiasts and professionals alike for its precision, musicality, and long-term listening satisfaction — a legacy that continues to define the EAR name today.
