Phasemation EA-220 Phono Amplifier

Description

Phasemation EA-220 MM / MC Phono Amplifier

All-Discrete Non-Feedback Circuit

At the heart of the Phasemation EA-220 is a fully discrete amplification circuit designed specifically for the very low-level signals generated by phono cartridges.

Rather than relying on operational amplifiers, Phasemation uses discrete components throughout the signal path and avoids global negative feedback.

This design philosophy aims to preserve subtle musical information, transient detail and natural harmonic structure while maintaining clarity and immediacy.

Dual-Monaural Architecture

The left and right channels are arranged in a dual-monaural configuration, helping reduce electrical interaction between channels.

Improved channel separation contributes to precise image localization, a more clearly defined soundstage and a convincing sense of depth and space.

This independent-channel approach is particularly important in phono amplification, where the signal arriving from the cartridge is extremely small and sensitive to unwanted interference.

Designed for MM and MC Cartridges

The EA-220 supports both moving magnet and moving coil cartridges, allowing it to integrate into a wide range of analogue systems.

For MM cartridges, the EA-220 provides a 47kΩ input impedance and 38dB of gain.

The dedicated MC input provides 470Ω input impedance and 63dB of gain, making the amplifier suitable for many low-output moving coil cartridges.

Rigid Low-Noise Construction

The EA-220 uses an 8mm aluminium front panel together with a 1.6mm copper-plated steel chassis.

This rigid mechanical structure is designed to reduce unwanted vibration and provide a stable environment for the sensitive phono amplification circuitry.

Heavy metal insulators further contribute to mechanical stability and help isolate the electronics from external vibration.

R-Core Transformer and Selected Audiophile Components

The internal power supply is built around an R-core transformer, selected for low magnetic leakage and quiet operation.

High-quality components include ELNA SILMIC II electrolytic capacitors, precision 1% metal-film resistors and carefully selected film capacitors.

This combination of power-supply design, component selection and mechanical construction reflects Phasemation’s focus on low noise and signal purity.

Phasemation EA-220 Key Specifications

Phasemation EA-220 Awards

The Phasemation EA-220 has received extensive recognition from leading Japanese audio publications, reflecting its combination of analogue engineering, musical performance and value.

Perfect Partner for the Phasemation T-600

For low-output moving-coil cartridges, the

Phasemation T-600 MC Step-Up Transformer

is an ideal partner for the Phasemation EA-220.

The T-600 provides passive transformer gain and impedance transformation before the signal reaches the EA-220, allowing the phono amplifier to operate through its MM input with a simple and carefully controlled analogue signal path.

Together, the

Phasemation T-600

and EA-220 create a highly synergistic Phasemation analogue front end for listeners using low-output MC cartridges.

The T-600 supports cartridges with an impedance range of 1.5Ω to 40Ω and provides 26dB of passive step-up gain, making it a particularly flexible companion for many moving-coil cartridges. :chatgpt-content-reference{index=”3″}

Japanese Analogue Engineering

Phasemation’s roots extend back to the 1970s, when the company operated as Kyodo Denshi System and developed precision measuring instruments and electronic systems.

Over the following decades, this engineering experience expanded into specialist audio technology, including phono products, step-up transformers and digital-to-analogue conversion.

The Phasemation EA-220 reflects this heritage by combining traditional analogue design principles with carefully controlled modern engineering in a compact phono amplifier.
