Product Description
Experience the Pinnacle of Sound Quality with the MA-2000 Amplifier
In the realm of audio amplifiers, enthusiasts can explore a variety of options, from semiconductors to tube amplifiers. Among them, tube power amplifiers featuring legendary tubes like the 2A3 and 300B stand out for their unique sound quality that continues to captivate audiophiles today.
Introducing the MA-2000, a monaural power amplifier meticulously crafted to deliver the exceptional sound produced by a 300B tube in a parallel single-ended circuit, complemented by a transformer-driven 2A3 circuit. Developed in 2016, this amplifier resonates with the desires of true audio connoisseurs.
Key Features
Superior Sound with 300B Parallel Single-Ended Design
The MA-2000 utilizes a fixed-bias, pure Class-A operation to maximize the innate qualities of the 300B tube. With dedicated power supplies for each PSVANE WE300B tube, we ensure optimal operating conditions for a robust output exceeding 25W, perfect for driving your speakers with clarity and power. The added timer control feature enhances reliability during startup.
Optimal Driving with SOVTEK 2A3
The amplifier employs the renowned 2A3 tube to optimally drive the 300B, maintaining stability and clarity through individually supplied fixed biases. This meticulous design ensures your speakers are driven with unwavering precision.
Non-Feedback Design for Authentic Sound
Experience the richness of music reproduction through our non-feedback amplifier, featuring triode tubes in every stage: 12AX7SRPP, 2A3, and 300B. This configuration delivers dynamic and expressive sound that only a non-feedback circuit can provide.
Premium LUNDAHL Transformers
Our choice of inter-stage and output transformers from LUNDAHL, Sweden, ensures the highest quality sound. With individually allocated fixed bias circuits for the 300B tubes, we maintain optimal performance and stability. The design supports both 4 and 8-ohm speakers for versatile compatibility.
Independent Power Choke Transformers
Each stage of the amplifier—the driver (2A3) and power stage (300B parallel single-ended)—is powered by independent choke transformers, eliminating interference and providing clear amplification for all signal levels, from the faintest whispers to powerful crescendos.
Innovative Noise Reduction Design
We prioritize sound purity with our comprehensive noise reduction features:
– A 5R4G rectifier tube that minimizes switching noise.
– Choke transformer-based rectifier circuits.
– Complete DC power supplies for all tube heaters, ensuring a clean signal.
Stylish Timer Indicator and Design
The MA-2000 features an elegant front panel with a dual-color LED timer indicator that transitions from red in standby mode to blue after one minute. Its refined appearance makes a striking addition to any audio setup.
