LAiV Crescendo VERSE R2R is an all-in-one audio component that combines an R2R DAC, preamplifier and headphone amplifier in a single device. Its compact format is designed to fit both a desktop setup and a main audio system, providing a management center for digital sources, headphone listening and connection to a system with an amplifier or active speakers.

The design is based on LAiV’s proprietary R2R ladder architecture, with a discrete balanced network consisting of individual resistors with a tolerance of 0.05%. This conversion section is complemented by native 1-bit DSD processing, an integrated sample-rate converter and an analog section with a discrete output buffer. The result is a versatile platform intended for those who want to manage different sources and listening modes without multiplying the system’s components.

R2R DAC and digital architecture

The heart of Crescendo VERSE is its proprietary R2R ladder network DAC. In this configuration, digital-to-analog conversion uses a precise arrangement of discrete resistors rather than relying on a single integrated converter. The stated 0.05% tolerance is part of the design focused on signal precision and reproduction consistency.

The R2R architecture was designed to preserve musical texture and tonal accuracy, with a presentation described as natural and also suitable for extended listening sessions. These characteristics make VERSE a DAC suited to those who pay attention to signal structure, image stability and listening continuity, without giving up the possibility of adjusting digital processing.

The device supports native 1-bit DSD conversion. In this mode, the DSD signal is reproduced without conversion to PCM, maintaining the intended path for this format. Several resampling options are also available for PCM and DSD sources, allowing the user to choose whether to retain the original format or apply a different sample rate.

• PCM resampling at 1x, 2x, 4x, 8x and 16x, up to 768 kHz or 705.6 kHz.
• DSD resampling to DSD64, DSD128, DSD256 and DSD512.
• Playback up to PCM 768 kHz and DSD256 via USB.
• Stated overall support up to PCM 768 kHz and DSD512 for the processing provided by the device.

Digital inputs and source management

Despite its compact dimensions, LAiV Crescendo VERSE provides four digital inputs: USB, Optical, Coaxial and I2S. This selection allows different sources to be connected, from the latest digital equipment to components already present in a system. The availability of the I2S input expands integration possibilities with compatible sources, while USB, Optical and Coaxial cover the most common digital connections.

Format specifications depend on the input used. Via USB, VERSE handles PCM from 44.1 kHz to 768 kHz and DSD from DSD64 to DSD256. The Optical input supports PCM from 44.1 kHz to 192 kHz and DSD64 via DoP. For the Coaxial and I2S inputs, the available data identify the presence of the connectors but do not report separate compatibility ranges; it is therefore advisable to refer to the source and the actual system configuration.

Control of the digital path allows processing to be adapted to the music library and personal preferences. The user can use native DSD handling or choose one of the available resampling options for PCM and DSD. This flexibility does not imply a single mandatory result; instead, it allows the system’s behavior with different formats and sample rates to be evaluated, keeping the choice within the device.

Three functions in a single component

VERSE is not just a DAC. Its configuration integrates a preamplifier with chip-based analog volume control, a discrete output buffer and a fully discrete headphone amplifier. It can therefore perform different roles within the same system: converting the digital signal, managing the listening level and driving headphones directly.

The preamplifier outputs include a balanced XLR pair and a single-ended RCA pair. Both outputs are available simultaneously, which is useful when connecting multiple system sections or maintaining a configuration with balanced and unbalanced connections. The XLR output provides approximately 4 Vrms with an impedance of 82 Ω; the RCA output provides approximately 2 Vrms with an impedance of 41 Ω.

The preamplifier section specifies total harmonic distortion of 0.0045%. The signal-to-noise ratio is equal to or greater than 120 dB on the balanced output and 110 dB on the single-ended output. These values describe the stated performance for the respective paths and help assess the integration of VERSE into an audio chain with an XLR or RCA input.

Headphone amplifier with two outputs

For personal listening, Crescendo VERSE offers two headphone outputs: a 4.4 mm balanced jack and a 6.35 mm single-ended jack. The headphone amplifier is discrete and features selectable gain, allowing the gain level to be set according to the headphones used and the desired listening experience.

• 4.4 mm balanced output: approximately 11 Vrms, 5.1 Ω impedance and up to 1100 mW per channel.
• 6.35 mm single-ended output: approximately 5.5 Vrms, 2.6 Ω impedance and up to 290 mW.
• Signal-to-noise ratio equal to or greater than 110 dB for the balanced output and 100 dB for the single-ended output.
• Stated total harmonic distortion of 0.008% for the headphone amplifier.

The presence of both connections makes it possible to use headphones with different terminations, choosing the connection corresponding to the available cable. Selectable gain adds an adjustment element to the headphone section, while the voltage, impedance and power data allow the pairing with a particular model to be examined more precisely. The device also includes comprehensive protection circuits, intended for everyday use with a wide range of headphones.

Connections, control and system integration

Thanks to its XLR and RCA outputs, VERSE can be connected to a system equipped with balanced or single-ended inputs. The preamplifier function allows it to be placed upstream of a power amplifier or another compatible amplification section, while the headphone output makes it possible to switch to personal listening without necessarily adding a dedicated amplifier.

The front display is a 20×7 dot-matrix LED model. It provides the visual interface for the information and settings supported by the device, in a format consistent with the product’s compact dimensions. The output phase can be set to positive or negative, providing an additional adjustment for system configuration.

The required power supply is 15 VDC / 2 A and uses a 5.5/2.5 mm female DC connector. Installation therefore requires verifying the correct availability of the power supply and the specified connection. Dimensions and weight may vary depending on the configuration and production process; this should be considered when planning placement on a desk or within a stackable system.

Who is LAiV Crescendo VERSE R2R intended for?

LAiV Crescendo VERSE R2R is intended for those seeking a central component for a compact digital system, without separating the DAC, preamplifier and headphone amplifier. It is an interesting solution for a desktop setup with multiple sources, as well as for a main system requiring XLR and RCA outputs and the ability to listen either through the system or directly through headphones.

The discrete R2R ladder network, PCM and DSD support, configurable resampling and two headphone outputs define a device focused on flexibility. Before purchasing, it is advisable to verify the formats supported by the source, the desired connection type and the headphone requirements, particularly when intending to use the 4.4 mm balanced output or the 6.35 mm single-ended output.
