The higher the sampling rate, the more advanced the time resolution and the more faithful the reproduced sound is to the original. 1-bit samples sound at an incredible high speed of 2,822,400 times per second (2.8MHz). In the time it takes CD to sample once, DVD-Audio samples 4 times and 1-bit samples the same sound 64 times. It is this greater sampling rate (64 times greater than CD) that makes 1-bit so revolutionary in reproducing sound. With the greatest time resolution ability ever achieved, 1-bit produces signals that are greatest in terms of faithful reproduction of the original signal and in transient response.

CD	22.6757	1.00	44,100	0 Hz -- 20 kHz	96
DVD-Audio	5.2083	4.35	192,000	0 Hz -- 96 kHz	144

*Theoretical value.

There is a considerable difference between amplifiers processing analogue signals and those that process digital signals. Analogue signals transmitted and amplified by analogue amplifiers suffer signal noise and degradation due to their nature. 1-bit amplifiers, however, transmit and amplify a pure 1-bit digital signal stream generated by a 7th-order (delta-sigma) modulation A/D converter. Processing digital signals instead of analogue signals,
1-bit amplifiers eliminate sound deterioration that plague analogue amplifiers. By taking full advantage of digital technology 1-bit amplifiers achieve high-quality, stunning sound.

1-bit amplifiers employ a simple switching operation, giving them several advantages over class-A and class-AB analogue amplifiers with the same output power. Compared to conventional amplifiers, power consumption is approximately half, while heat radiation is only one-fifth, allowing 1-bit amplifiers to be one-third the size. Compact and energy efficient, 1-bit amplifiers shatter the conventional image of amplifiers being bulky and unsound from environmental and economical viewpoints.
