Delivers 550 watts per channel at 4-ohms, providing uncompromised power and precision.
Features a bridge-tied load (BTL) architecture for perfect symmetry and diaphragm accuracy.
Utilizes dual 1 kVA toroidal transformers with circular cores for cleaner and responsive power.
Technical Audio Devices Laboratories (TAD) has unveiled the TAD-M2500TX, a standout addition to its prestigious Evolution Series of hi-fi audio components. This two-channel power amplifier is engineered to deliver exceptional performance, boasting a robust 550 watts per channel at a 4-ohm load. The M2500TX embodies TAD’s commitment to precision and power, making it a noteworthy contender for audiophiles seeking uncompromised sound quality.
At the heart of the TAD-M2500TX lies a meticulously designed BTL (bridge-tied load) architecture, ensuring ultimate symmetry in both circuitry and layout. This balanced configuration, extending from the input to the output stages, guarantees that the positive and negative currents driving the speaker units are identical, resulting in unparalleled diaphragm precision. The amplifier is housed in a newly redesigned machined aluminum chassis, which eliminates joints and reduces grounding impedance, further enhancing the system’s overall symmetry and stability.
Power delivery is managed through dual high-capacity toroidal transformers, each rated at 1 kVA. The secondary coils are directly integrated into the power supply circuit, minimizing contact points and preserving the purity of the electrical flow. Additionally, the transformer cores have been redesigned from square to circular cross-sections, reducing magnetic flux leakage and vibrations. This enhancement ensures a cleaner and more responsive power supply, contributing to the amplifier’s ability to reproduce music with both power and agility.
The TAD-M2500TX also features an advanced vibration-control system. Encased in a solid 90-kilogram aluminum block, the amplifier is supported by a three-point structure with internally inverted spikes that isolate it from external vibrations. This design minimizes interference from surface-induced vibrations, allowing for a more concentrated and dynamic audio output. Furthermore, the amplifier includes heavy-duty, extra-large speaker terminals that reduce mechanical and electrical stress on connected cables, ensuring stable and high-fidelity sound transmission.
Offering versatility for audiophiles, the TAD-M2500TX supports bi-amping configurations for compatible speakers. This capability allows separate amplification of tweeters and woofers, eliminating interference between speaker units and enhancing sound clarity. With its combination of powerful output, sophisticated design, and technical excellence, the TAD-M2500TX stands as a testament to TAD’s legacy of delivering superior audio performance.
