The distortion reduction in the THX AAA technology has an additional benefit: it dramatically reduces power supply-induced distortion and noise — a high PSRR (power supply rejection ratio).
In any amplifier, when the power supply works hard under heavy load conditions, it can introduce unwanted distortion and noise in the output signal. The THX patented solution is particularly effective in reducing these components to unprecedentedly low levels.
That means more of what you hear is music, and less of what you hear is the character of the power supply associated with the amplifier.
Combining this with meticulous layout and design, the THX AAA technology delivers a signal- to – noise ratio (SNR) in excess of 130 dB — this is 30 dB greater than most amplifiers. That’s 30 times less noise than typical amplifiers — the perfect amplifier for a high-resolution audio playback system.
