The Future of Digital is Now

To some audio connoisseurs, the word “digital” was historically laden with negative connotations due to shoddy implementation in budget systems and subwoofers. But times—and technologies—have changed, thanks to the pioneering research and development of Lyngdorf Audio. More than two decades ago, Lyngdorf Audio rewrote the playbook on digital audio, and the result is that our digital systems are now the only way to enjoy unbiased reproduction of recorded music, with each note delivered exactly as the musician and sound engineer originally intended.

The latest Lyngdorf Audio “Power DAC”—digital amplifier—is the TDAI-2170, which has its roots in the legendary Lyngdorf Audio Millennium amplifier, still available in its present MK4 version.

Stability in Signal Processing
Like all Lyngdorf Audio fully digital components, the TDAI-2170 requires extremely stable signal processing because it is not possible to implement correction systems like feedback control.

This level of accuracy in signal processing is achieved by an advanced power supply, which delivers a correct and stable voltage to the output stage even in locations with very poor and fluctuating mains power. Together with effective grid noise elimination, this removes the need for an external mains filter or power conditioner.

In simpler terms, instead of reducing the dynamic range at normal listening levels by attenuating the signal level, the TDAI-2170 uses the power supply as volume control. There is absolutely no audible noise from the amplifier, simply full fidelity from lowest to highest volume settings.

Modulated by Width, Not by Code
In Lyngdorf Audio’s fully digital signal processing, a digital input is processed only once in a pulse width modulator (PWM) based on the patented Equibit™ technology originally developed for the Millennium amplifier (as opposed to pulse code modulation). The result is potent amplification which does not stress or color the sound. The sound in the recording is the sound you hear—it’s that simple.
