Metrum Acoustics Adagio Preamplifier / DAC

The R2R ladder architecture uses a precise array of resistors to convert digital signals to analog, which avoids the artifacts often associated with standard delta-sigma chips. This results in a more natural, organic sound signature that many audiophiles prefer for its realistic texture and depth.

Yes, the Adagio features an integrated digital preamplifier with volume control. This allows you to connect it directly to a power amplifier, effectively simplifying your signal path by removing the need for a separate standalone preamp.

A non-oversampling design processes the digital signal without the mathematical interpolation used in standard DACs. By avoiding these extra processing steps, the Adagio preserves the original timing and phase of the recording, which contributes to a more authentic and engaging soundstage.

The Adagio is well-equipped for various sources, offering one USB input, two BNC coaxial inputs, two Toslink optical inputs, and one AES/EBU XLR input. This variety ensures compatibility with most digital transports, streamers, and computers.

No, the Adagio is specifically optimized for PCM audio formats. It supports up to 24-bit/384 kHz resolution, focusing on high-fidelity playback for standard digital music libraries.

Metrum’s forward correction technique is designed to minimize the linearity errors inherent in R2R ladder designs. By correcting these micro-deviations, the DAC maintains high accuracy even at very low signal levels, ensuring that subtle details in your music remain clear and audible.
