A Digital Heart, an Analog Soul
The Lector Audio DIGITUBE S-192/DSD Digital-to-Analog Converter (DAC) is the result of a unique approach that combines the best of digital and analog technologies. Its fully tube-based output stage delivers a warm and musical sound signature, while its cutting-edge digital circuits ensure precise conversion of high-resolution signals.
This DAC supports PCM signals up to 24-bit/192 kHz as well as the DSD format, offering broad compatibility with high-resolution audio files. The proprietary conversion chip developed by Lector ensures faithful reproduction of even the subtlest musical nuances.
Versatile Connectivity for All Sources
The DIGITUBE S-192/DSD features a wide range of digital inputs to accommodate all types of equipment:
- Asynchronous USB input for computer connection
- S/PDIF inputs via RCA and BNC connectors
- AES/EBU input via XLR connector
- Optical Toslink input
Additionally, a Word Clock input allows synchronization of the DAC with other digital devices for optimal precision. On the output side, it offers unbalanced RCA and balanced XLR connectors for seamless integration into any system.
Italian Design Combining Aesthetics and Functionality
The DIGITUBE S-192/DSD boasts an elegant, typically Italian design. Its brushed aluminum front panel is adorned with a discreet LED display that indicates the input signal’s sampling rate. A single push-button allows source selection, ensuring everyday ease of use.
The device rests on four damping feet that effectively isolate it from vibrations. Inside, meticulous shielding and optimized wiring help preserve the integrity of the audio signal.
Proprietary Technology in Service of Music
Lector has developed several innovations for this DAC, starting with its S.C.R. (SPDIF Circuit Reconstruction) technology, which regenerates the digital signal before conversion. The proprietary U2S-N USB circuit ensures high-quality asynchronous connections with computers.
The tube-based output stage uses carefully selected components and point-to-point wiring to maintain the richness of the signal. The result is a highly musical sound, combining transparency with analog warmth.
Immersive and Captivating Listening
The DIGITUBE S-192/DSD stands out for its ability to deliver a wide, three-dimensional soundstage. Instruments are precisely positioned in space, with remarkable separation and definition. The rich and natural midrange particularly enhances vocals.
In the bass, this DAC provides deep, well-articulated lows without any dragging effect. The treble is smooth and free from harshness, even at high volumes. Its impressive dynamics faithfully reproduce both subtle nuances and intense passages.
The Perfect Companion to Rediscover Your Music Collection
Thanks to its high performance, the DIGITUBE S-192/DSD allows you to rediscover your favorite albums in a new light. High-resolution recordings reveal their full potential, uncovering details previously unheard. Even compressed files benefit from noticeable improvement thanks to its meticulous signal processing.
This DAC integrates seamlessly into a high-end audio system but can also elevate a more modest setup. Its versatility makes it an excellent choice for anyone looking to significantly enhance the sound quality of their digital sources.
