Technical Audio Devices Laboratories, Inc. has unveiled its latest innovation, the TAD-M2500TX two-channel power amplifier, marking a significant addition to its acclaimed Evolution Series of high-fidelity audio components. This new amplifier is designed to elevate the listening experience with its state-of-the-art features and performance enhancements.
Cutting-Edge Design and Performance
The TAD-M2500TX amplifier features a completely reimagined circuit layout, upgraded power transformers, and a newly designed machined aluminum chassis. It delivers an impressive 550 watts of power per channel at 4 ohms, providing a powerful audio output when paired with TAD speakers from the Evolution Series. This combination ensures that listeners experience the exceptional clarity and dynamism that TAD components are renowned for.
Ultimate Symmetry in Circuitry and Layout
At the heart of the TAD-M2500TX’s design is a commitment to achieving ultimate symmetry in its circuitry. The amplifier employs a bridge-tied load (BTL) design connecting two separate amplifiers in a balanced configuration for each channel. This setup ensures that both positive and negative power supplies maintain perfect symmetry. Additionally, the redesigned machined aluminum chassis features a joint-free design that minimizes grounding point impedance, enhancing the overall symmetry between channels and signals.
High-Capacity Transformers with Greater Purity and Efficiency
The TAD-M2500TX is powered by dual high-capacity toroidal transformers, each rated at 1 kVA. These transformers are designed to enhance power supply purity by minimizing contact points with leading wires. Using oxygen-free copper for terminals and mounting screws, the amplifier effectively eliminates magnetic distortions. Furthermore, the circular transformer core design reduces unwanted magnetic flux leakage and vibrations, resulting in a power supply that is both pure and responsive.
Power Rating of 550 Watts per Channel at 4 Ohms
Delivering an astounding 550 watts per channel at 4 ohms, the TAD-M2500TX employs a simplified Class-D single-output stage utilizing ultra-low on-resistance power MOSFET devices. This combination minimizes power losses and ensures high-speed responses, producing powerful yet agile sound reproduction. The machined aluminum chassis also contributes to excellent heat dissipation, further enhancing performance.
Meticulous Vibration-Control Design
Constructed from a solid 90 kg block of aluminum, the TAD-M2500TX’s chassis is designed to counteract external vibrations. Its joint-free design stabilizes both ground potential and audio signals, leading to improved sound quality. The three-point support structure with internally inverted spikes isolates the chassis from vibrations, resulting in more condensed and energetic audio reproduction. Additionally, heavy-duty speaker terminals reduce mechanical and electrical stress on connected cables, optimizing their performance.
Bi-Amping Option for Enhanced Clarity
The TAD-M2500TX offers a bi-amping option for compatible speakers, allowing one amplifier to connect to the tweeter terminals and another to the woofer terminals. This configuration eliminates interference between speaker units, enhancing separation and clarity. The bi-amping capability enables a more refined and immersive listening experience, showcasing the full potential of both the amplifier and speakers.
