Sony - Amplificatore di potenza TA-N88B, preamplificatore TA-E88B - High End Set stereo

Legendary and incredible rare High End set from Sony, the amazing TA-N88B (V-fet) amplifier Class A and the preamplifier from the same series TA-E88B. STUNNING and amazing sound, beautiful and pleasant, relaxed sound.


DESCRIPTION:

Now that high-power amplification has become a reality for outstanding home sound reproduction and, of course, commercial sound reinforcement applications, amplifier efficiency is an important factor in judging component value.

With the new Sony TA-N88 power amplifier, high efficiency, power and performance combine to provide excellent value. But before getting into the details of efficiency and performance, the need for high power itself is worth considering.

In short, high power levels are needed for realistic reproduction of transient musical peaks. For the major duration of a given piece of music, an amplifier typically may be required to deliver only 10-20 percent of its full power output, but for accurate reproduction, according to today's high-fidelity standards, sharp-attack tones require high power levels.

For example, the sharp strike of cymbals in a symphony or the drum beats that punctuate a rock concert, even a sudden blast from a trumpet, are transients requiring lots of power.

This brings us back to the new Sony TA-N88. Rated at 160 watts per channel (minimum RMS at 8 ohms, from 20Hz to 20kHz, with no more than 0.5 percent total harmonic distortion). In the TA-N88, Sony engineers have utilized Pulse Width Modulation (PWM) design, an advanced new breed of amplifier circuitry, to solve the problem of amplifier efficiency.
