TAD M700S Stereo amplifier

TAD’s philosophy has remained unchanged for over 40 years, and that is to deliver sound that conveys the full range of emotions without alteration.

This philosophy has driven us to develop technology for the reproduction of music in its purest form. Over the past four decades.

TAD have advanced the ultimate limits of quality audio reproduction to achieve the finest in performance.

And now, our efforts have culminated in the fully balanced M700 monaural power amplifier with an output of 700 watts at 4 ohms and the M700S two-channel power amplifier.

These two amplifiers have converted into reality the ideal attributes in providing flawless speaker-driving capability, symbolizing uncompromised design and quality that only TAD can provide.

The M700 and M700S employ a newly designed cast-aluminum chassis that boasts a high internal loss factor for vibration, eliminating inherent sympathetic vibration at unwanted frequencies.

Components are laid out optimally inside the chassis to stubbornly resist vibrations induced by sound pressure from a speaker system. The low-impedance aluminum chassis demonstrates high electric stability.

Moreover, these amplifiers are supported by four height-adjustable spike feet, each having a single point of contact with the surface on which it stands.

This ingenious design keeps vibration transmitted through the floor from affecting the components inside the case and keeps delicate audio signals from being masked by vibration-induced distortion.

The result is more condensed and energetic audio reproduction and yet with spatial nuance of the music retained intact.

Our years of expertise in achieving audio quality and reliability has culminated in twin gigantic power transformers with the total ratings of 2.8 kVA.

In the production line of the M700 and M700S, our certified artisans manually wind insulating sheets around the core of the transformer, eliminating the need for a bobbin so as to increase the binding between the primary and secondary coils.

The coil is directly connected to the first stage of amplification to increase the purity of power supply and achieve more responsive and consistent audio reproduction.

In addition, four custom-built, sturdy 33,000 μF capacitors help effortlessly deliver dynamic and smooth sound with excellent transient response for which the M700 and M700S were designed.

True to TAD’s long-held design philosophy of “Simple is best,” the M700 and M700S reduce the number of components needed for the first stage down to a minimum so as to allow music signals to be amplified in their purest form and go through the circuit without losing even the subtlest information.

A pair of FET devices carefully hand-picked by our certified artisans in the production line was incorporated into the amplifier’s input circuit, which improves the operational stability of amplification.

As a result, every production unit of the M700 has identical performance characteristics, and the M700S delivers identical performance between the left and right channels.

In addition, the new DC servo circuit stabilizes amplification, resistant to changes in the operating temperature and magnitude of input signals and eliminating fluctuations in sound intensity.

All this attention to detail ensures that these amplifiers produce a powerful, condensed sound with deep, rich bass, allowing the listener to have a truly immersive stereophonic experience.
