Inspired by Architectural Grandeur

Inspired by the monumental beauty of architecture, this device was created to reveal the full scale, richness, and emotional depth of music. A precision-engineered R-2R DAC designed for natural, dynamic, and lifelike reproduction.

The Inspiration

During the first visit to Barcelona, the founder encountered the extraordinary presence of La Sagrada Família. Its immense scale, intricate details, and harmony between strength and softness became the inspiration.

Music, like architecture, should have presence. It should be powerful yet delicate, complex yet natural.

R-2R DAC Architecture

At the heart is a custom discrete R-2R DAC architecture based on sign-magnitude conversion technology. Unlike conventional Delta-Sigma DAC designs, the R-2R approach converts digital signals directly into analog through precision resistor networks. This allows the device to preserve musical texture, micro-dynamics, and natural harmonic structure.

The device uses dual R-2R networks for positive and negative signal paths. This sign-magnitude architecture reduces non-linearity across different signal levels, maintaining consistent accuracy even with low-level musical details.

Precision Components

The DAC section features a custom 27-bit precision R-2R module with ultra-high precision thin-film resistors. Each digital signal passes through a carefully optimized FPGA processing stage before conversion, ensuring maximum accuracy and musical integrity.

FPGA Processing

Advanced digital signal management is handled through FPGA processing. High precision upsampling is performed with 67-bit calculation accuracy, reducing rounding errors and maintaining signal integrity throughout the conversion process.

Format Support

PCM support up to 384kHz / 32-bit and DSD256. DSD playback is handled through FPGA processing, converting DSD signals while preserving the advantages of the R-2R conversion architecture.

S/PDIF Blade Technology

Digital transmission is not only about data. It is also about timing. S/PDIF signals are affected by waveform distortion, threshold detection, and jitter.

With nine selectable levels, S/PDIF Blade allows the device to adapt to different digital sources, improving signal locking stability and reducing timing errors.

USB Interface

The device features a custom USB interface developed with Amanero. Supporting USB Audio Class 2.0, it provides stable high-resolution playback with PCM up to 384kHz and DSD256.

Power Supply

The power supply is designed with the same philosophy as high-performance amplifier circuits. Nine independent power supply sections are isolated to minimize interference and provide clean energy for each critical circuit stage. Simultaneous use is possible.
