Phasemation EA-550 Phono Amplifier

The Phasemation EA-550 is a high-end phono amplifier designed for true analog performance. It uses a fully discrete, non-feedback circuit to reproduce music with clarity and emotion. As a result, it reveals the full depth and character of vinyl recordings.

Built as a dual-mono design in two separate units, the EA-550 focuses on purity and precision. In addition, it combines advanced circuit design with premium components. Therefore, it delivers a highly detailed and natural listening experience.

Dual-mono construction

The EA-550 uses two separate units for left and right channels. This layout improves channel separation and reduces interference. As a result, it creates a wider and more accurate soundstage.

Non-feedback discrete circuit

The amplifier uses a fully discrete, all-stage symmetrical non-feedback design. Unlike feedback circuits, it avoids time delay and distortion. Therefore, it produces a more direct, dynamic, and expressive sound.

Precision MC transformer

A newly developed MC transformer uses a special split winding structure. It also features high-purity copper for improved signal transfer. Because of this, it enhances detail and maintains signal integrity.

Flexible cartridge support

The EA-550 includes three inputs with MM and MC compatibility. Inputs 1 and 2 also support balanced XLR connections. As a result, it works with a wide range of turntables and cartridges.

Advanced equalization options

The amplifier offers multiple playback curves, including RIAA, Mono1, and Mono2. This allows accurate playback of different record types. In addition, a low-cut filter helps reduce unwanted low-frequency noise.

High-quality components

The EA-550 uses carefully selected audio-grade parts throughout. For example, it includes metal film resistors, mica capacitors, and ELNA capacitors. Therefore, it ensures stable performance and high sound quality.

Low-noise power supply

The power supply uses separate R-core transformers for each stage. It also includes low-noise diodes and high-grade capacitors. As a result, the amplifier delivers clean power with minimal noise.

Resonance and vibration control

The chassis uses thick aluminum and copper-plated steel for strength. In addition, heavy metal feet reduce external vibrations. Therefore, it maintains stability and preserves sound clarity.

Enhanced analog playback

The EA-550 includes a degauss function for MC cartridges. This helps restore clarity over time. As a result, it keeps playback clean and consistent for long-term use.
