Phasemation EA-1200 Phono Equalizer Amplifier

The Phasemation EA-1200 Phono Equalizer Amplifier is a reference-level vacuum tube phono stage from Phasemation, designed to extract exceptional musical detail and emotional realism from vinyl playback. Built around a non-feedback LCR equalizer architecture, the EA-1200 combines advanced transformer design, precision circuitry, and premium construction to deliver a natural, highly dynamic listening experience.

With dedicated MC and MM support, multiple equalization curves, and a robust tube-based power supply, this phono amplifier is engineered to reveal the full character and nuance of high-quality analog recordings.

Key Highlights

Precision MC Step-Up Transformer

The EA-1200 features a specially tuned moving-coil step-up transformer derived from the Phasemation T-1000 Step-Up Transformer. This carefully optimized design helps deliver exceptional signal purity and improved resolution when used with MC cartridges.

Advanced Non-Feedback LCR Equalizer

A sophisticated LCR equalizer circuit operates without negative feedback, helping preserve speed, dynamics, and musical detail. The circuit uses an SRPP configuration with ECC-803S tubes to provide wide dynamic range and expressive, lifelike sound reproduction.

For additional flexibility, three selectable equalization curves are available:

• RIAA for standard stereo LP playback
• Mono 1 (DECCA) for select mono recordings
• Mono 2 (Columbia) for vintage Columbia mono pressings

Independent left and right channel operation further enhances channel separation and clarity.

High-Performance Tube Power Supply

The EA-1200’s power supply is based on the design used in the Phasemation EA-1000 Phono Equalizer Amplifier. It incorporates a large-capacity R-core transformer, magnetically shielded choke coils, and 5U4G rectifier tubes to deliver stable, low-noise power. A precision three-terminal regulator helps maintain an excellent signal-to-noise ratio for clean, transparent playback.

Premium Construction and Connectivity

Attention to mechanical design and materials helps ensure both durability and optimal sonic performance. The EA-1200 features a solid chassis with a 10 mm thick aluminum front panel designed to minimize vibration and magnetic interference.

High-quality connectors—including Flutech RCA terminals and Neutrik-plated XLR inputs—provide reliable, high-integrity connections for demanding audio systems.

Designed for Serious Vinyl Enthusiasts

With its advanced tube circuitry, precision transformers, and meticulous build quality, the Phasemation EA-1200 offers a compelling solution for audiophiles seeking a phono stage capable of revealing the depth, nuance, and emotion captured in vinyl recordings.
