Phasemation MA-3000

• MA-3000 Product Information

Main feature

The output stage employs 300B triodes in a parallel single configuration, ensuring a maximum output of 25W

Vacuum tube amplifiers are by no means mere nostalgic relics. The vacuum tube is a device capable of extraordinary signal transmission speeds, and when properly utilized, it can deliver sonic expression that surpasses even solid-state amplifiers. This is why Phasemation is dedicated to using vacuum tubes—specifically, directly heated triodes, which offer the ultimate in expressive power. The MA-3000 features a parallel single-ended configuration of the 300B, the iconic triode. By keeping the circuitry simple, it achieves a reproduction that is both pure and remarkably high-speed.

Transformer-Coupled EL34 Drive Stage, Engineered for very detailed Linearity

The audio signal is driven from an EL34 connected in triode mode, passing through an interstage transformer to the output stage. Notably, while conventional driver stages function merely as voltage amplification, the MA-3000—mirroring the flagship MA-5000— utilizes the driver stage itself as a power amplification circuit. This unique configuration dramatically reduces impedance and maximizes signal linearity.

Enhanced High-Speed Performance and a Wider Sound Stage with a Newly Designed Toroidal Power Transformer

The redesign of the MA-3000 introduced a completely renewed power transformer. The newly developed, high-regulation toroidal power transformer drastically lowers power circuit impedance. This critical advancement delivers enhanced high-speed performance and projects a remarkably wide, immersive sound stage.

Exquisite Sound Achieved Through the Flagship-Inherited Vibration-Damping Structure

The interior of any amplifier is inherently prone to noise sources and micro-vibrations—a persistent challenge for audio engineers. Large power transformers, in particular, generate substantial physical vibration, making precise control over these forces a critical factor in final sound quality. The MA-3000 seamlessly inherits the advanced transformer isolation technology developed for the flagship MA-5000, eliminating unwanted noise to deliver pristine, high-resolution playback.

Evolution of Pure Audio: Eradicating Leakage via Flux Control

Leakage magnetic flux kills audio resolution. The MA-3000 eliminates this threat entirely. Beyond comprehensive shielding for all transformers and coils, its architecture is precision-engineered to isolate core vacuum tube signal paths, ensuring absolute sonic transparency.

Precision-Engineered Aesthetics: Masterful Design in Every Detail

Unlike conventional tube amplifiers designed to be played uncovered, Phasemation engineered this unit to achieve optimal acoustic performance with its cover securely in place. The chassis top features intricately crafted ventilation holes incorporating traditional Japanese patterns, seamlessly blending functional cooling with artistic elegance. This is complemented by the front panel, which showcases Phasemation’s signature modern, thick, and precisely slanted profile
