*This product is an amplifier which has been designed using time domain theory in
order to maximize speaker operation and performance.
《What is time domain theory?》
Time domain recreates the changes that occur in sound waves over time from the
moment of output until their disappearance. Its purpose is to reproduce those
sound waves that are as close as possible to the original recorded sound.
Time domain audio systems allow sound orientation and the nuances that are
added by recorded performers to be faithfully reproduced.
