MA-5000

PHASEMATION MA-5000 is a flagship monaural vacuum tube power amplifier from Japan, designed to reproduce music with exceptional dynamics, expressive detail, and natural tonal character. It uses parallel single-ended PSVANE WE-211 output tubes, driven by a transformer-coupled WE-300B stage, to deliver powerful performance while preserving the musical qualities of triode amplification.

Key Features

• Pure Class A Operation: Uses parallel single-ended PSVANE WE-211 output tubes for powerful and expressive sound reproduction.
• Transformer-Coupled Driver Stage: A PSVANE WE-300B tube drives the WE-211 output stage for stable operation and dynamic performance.
• All-Triode Circuit Design: Uses ECC803S, WE-300B, and WE-211 tubes in a non-feedback circuit to preserve musical detail and dynamics.
• Premium Lundahl Transformers: Swedish-made interstage and output transformers are selected for signal transmission and loudspeaker driving performance.
• Balanced and Unbalanced Inputs: Supports both XLR and RCA connections, with adjustable input attenuation of −3 dB, −6 dB, and −10 dB.
• Independent Power Supplies: Separate power transformers for the driver and output stages help reduce interference.
• Low-Noise Design: Uses 5R4G rectifier tubes, choke-filtered high-voltage power supplies, and DC-powered tube heaters to minimize noise.
• Premium Construction: Features thick aluminium panels, TAOC cast-iron insulators, Furutech speaker terminals, and a decorative glass tube cover inspired by traditional Japanese cloisonné craftsmanship.
• Award Recognition: Received the Stereo Sound Grand Prix 2023 and other Japanese audio awards.
