TAD-M2500TX – New Amplifier will be Available in Mid-April 2025
15.04.2025 06:21 | ~1 minute read
Technical Audio Devices Laboratories has introduced the TAD-M2500TX stereo power amplifier – the device sports a completely rethought circuit design, uses upgraded power transformers and a redesigned machined aluminum chassis (machined from a 90 kg solid block of aluminum).
The TAD-M2500TX weighs 42 kilograms and offers 2 x 550 W into a 4 Ohm load at 0.05% distortion and 112 dB signal-to-noise ratio. The amplifier operates in a frequency range from 10 Hz to 50 kHz and has a gain of 29.5 dB. TAD-M2500TX uses a bridge-tied load design that connects two amplifiers in a balanced configuration in the circuit from input through output stages. The redesigned machined aluminum chassis has no joints, and the amplifier's grounding scheme has also been upgraded.
The model uses twin high-capacity toroidal transformers with a power rating of 1 kVA each. All connections inside the device are made of oxygen-free copper coated with nonmagnetic materials to eliminate even the slightest magnetic distortions. The amplification scheme itself remains the company's favorite class D, but quite tricky - simplified Class-D single-output-stage consisting of power MOSFET devices with ultra-low on-resistance.
