Yamaha A-S801 outweighs Cambridge with its 100/8 vs 30/8 W/Ohm. The A-S801 uses the ES9010K2M from ESS Technology, Inc. as the digital-to-analog converter. They selected it after a careful study of all the strengths, which in addition to high-precision processing of 32-bit audio signals include the ability to process large amounts of audio data with a resolution of 384 kHz in PCM format and a native resolution of 5.6 MHz in DSD format, powerful low-frequency register transmission and high definition in high frequency register. Moreover, the microcircuit contains a 2-channel DAC operating on the principle of a double differential.
The amplifier is equipped with a massive toroidal transformer of the audiophile class, which is mounted in the center of the anti-resonant chassis. The device operates in A / B class, which involves significant heating of its output stages. For the most effective cooling, they are mounted on massive radiators, separate for the left and right channels. Thus, the device will cope with the work of speakers with a complex impedance characteristic. The entire amplifier circuit is symmetrical to better separate stereo channels and minimize crosstalk.
