LAiV Crescendo Verse R2R DAC Preamplifier Headphone Amplifier 32bit 768kHz DSD256 Silver
The LAiV Crescendo Verse is a high-end, all-in-one audio solution combining a discrete R-2R DAC, a discrete buffered output preamplifier, and a discrete headphone amplifier in a single compact and versatile device. It is based on LAiV's proprietary R-2R architecture, designed to deliver natural tonal reproduction and detailed precision, as well as native 1bit DSD processing combined with an integrated sample rate converter for flexible handling of PCM and DSD formats up to PCM 32bit 768kHz / DSD256, ensuring extensive compatibility with modern high-resolution audio sources.
Compact yet comprehensive, the Crescendo Verse offers a wide range of connections with USB, optical, coaxial and I2S inputs, balanced XLR and single-ended RCA analog outputs, as well as balanced and single-ended headphone outputs, with an amplifier capable of delivering up to 1100mW per channel in balanced output and 290mW in single-ended output, suitable for both sensitive headphones and power-hungry models. The front panel features a matrix LED display and comprehensive controls, while the entire system is designed to fit easily on a desk or into a main audio system.
LAiV Crescendo Verse: R-2R architecture and digital processing
At the heart of the Crescendo Verse is LAiV's proprietary R-2R DAC architecture, based on a network of high-precision resistors for natural, smooth, and detailed sound reproduction, offering minimal coloration and excellent dynamics.
The internal processor, powered by an Altera® Cyclone® FPGA chip, also handles advanced digital processing, including native 1bit DSD modes, which allow DSD to be played in its native format without conversion, as well as an integrated sample rate converter that offers PCM and DSD resampling options for optimal compatibility with different sources and audio libraries.
Native 1bit DSD processing allows DSD streams to be played back without prior conversion to PCM. This approach fully respects the nature of the DSD signal, preserving its temporal structure, precision, and original sound signature throughout the processing chain. Designed for audiophiles seeking the most faithful reproduction of DSD recordings, this mode ensures a direct, unaltered signal path from the source to the analog output.
DSD processing modes
| Function | DSD Native | DSD Multibit |
|---|---|---|
| Processing | True 1bit DSD | DSD converted to multibit |
| Signal Path | Direct, unaltered | Optimized for stability |
| Best For | Pure DSD albums | Mixed sampling rate libraries |
| Track Switching | May produce pop with rate change | Smooth, silent transitions |
| Recommended Use | Critical listening | Daily listening, playlists |
LAiV Crescendo VERSE: Extensive connectivity
Despite its compact size, the Verse offers a full range of digital inputs:
- USB for direct connection to a computer or digital source.
- Optical Toslink for conventional digital audio devices.
- Coaxial.
- I2S for high-fidelity compatible sources.
In terms of output connectivity, the Crescendo Verse features a discrete preamplifier with buffered output that delivers both balanced XLR outputs (~4Vrms) and single-ended RCA outputs (~2Vrms). These outputs can operate simultaneously, facilitating integration into multi-component audio systems, whether with active speakers, external power amplifiers, or other analog components.
LAiV Crescendo Verse: Powerful discrete headphone amplifier
The headphone section of the Verse uses a discrete topology with a gain selector (Low/Medium/High), suitable for both sensitive and demanding headphones. In high gain mode, it delivers up to 1100mW per channel via the balanced 4.4mm jack output. In single-ended 6.35mm jack mode, it provides up to 290mW per channel, enough to drive very demanding headphones. Integrated protection circuits ensure reliable everyday use.
LAiV Crescendo Verse: Volume control & versatility
The LAiV Crescendo Verse features a built-in analog volume control, designed to offer precise, gradual, and perfectly controlled adjustments without sudden level changes. It comes with a remote control, allowing for comfortable adjustment with both sensitive headphones and a complete audio system. Thanks to this analog volume control, the VERSE can be connected directly to active speakers or used as a preamplifier in combination with an external power amplifier, eliminating the need for an additional device.
