Product Description

6moons Bluemoon Award winner, read the full review here.

The ultimate challenge: "reproduce every drop of recorded material that lives and breathes within the master tape." For over twenty two years, ESOTERIC has drawn on TEAC's extensive heritage in audio reproduction to forge state of the art sound technologies. These efforts have now come to fruition in ESOTERIC's Master Sound Works product category. The design of the E-03 phonostage preamplifier is focused on one thing...the re-creation of a masterpiece.

L/R dual mono construction that stands by ESOTERIC's philosophy:
Identical R-core power supply transformers, power boards, and audio boards are mounted on each channel. By avoiding the left and right channels having to share these components, the E-03 has achieved the ideal signal path and separation, while ensuring that it has power to spare. Moreover, the components and the boards are positioned symmetrically to achieve mechanical stabilization.

Audio circuitry with all discrete construction:
The Esoteric E 03 contains MC head amplifier that doesn't compromise the purity of the musical signals at low input levels, and an NF-CR type RIAA amplifier that achieves both excellent RIAA characteristics and NF reduction. To ensure extensive headroom and transfer, and a wide range of musical signals with plenty of power to spare, the RIAA and output buffer amplifiers both use high voltage circuits. These features achieve the vivid reproduction of every expression of the music, from dynamic power to subtle nuances.

Settings that exploit the full potential of your cartridge:
Listening to a masterpiece with a beloved cartridge is one of the true pleasures of your analog experience. In recent years, various models of MC cartridges have entered the market, including a type with very-low inner resistance. Placing high importance on supporting various types of MC cartridges, the E-03 allows you to select from two MC-compatible input systems and seven impedance positions. The E-03 also allows you to select between three different load capacities-0pF, 100pF and 330pF-supporting the specified load capacities for MM cartridges.

Taking extra care for simple construction to achieve high sound quality:
The Esoteric E03 does not have a microprocessor, thus eliminating the noise produced by such components. In the pursuit of high sound quality, input and load are switched on the audio board. By minimizing switching functions to eliminate switching circuits, we have optimized the signal paths which greatly reduces noise and interference associated with conventional designs.

"DEMAG"position located on each input controller helps to demagnetize MC cartridges and signal path or step-up transformers very easily.

The chassis structure and a highly rigid body provide additional noise reduction:
The dual split chassis structure prevents the influence on the audio circuit of flux leakage from the power transducer and effectively stiffens the body. The excellent internal weight balance and the three-point support provided by the unique hardened steel pin-point feet, minimize the negative effects of unnecessary resonance.

Sophisticated sculpturing and a beautiful thick aluminum body:
The blast finish and short scratch finish contrast beautifully on the E-03's body. The artistic sculpting of the screw less top panel and rounded corners results in a beautiful integration with ESOTERIC's high-end products.
