Product Overview & Specifications
The Garlubidor Phantom R-2R DAC is a high-performance digital-to-analog converter engineered to deliver analogue warmth, precise spatial imaging, and high musicality. Built around a discrete 24-bit R-2R resistor ladder architecture with four sets of 0.005% ultra-high-precision matched resistor networks, it bypasses traditional delta-sigma chipsets in favor of a true ladder network that prioritizes natural timing and harmonic accuracy.
Capable of functioning as both a standalone DAC and a dedicated preamplifier, the Phantom incorporates a relay-switched resistor-ladder volume control driven by a front-panel rotary encoder for consistent impedance and low-level channel matching. Powered by an internal low-noise linear power supply with a custom O-core transformer, it features dual precision active crystal oscillators (45.1584 MHz / 49.152 MHz) and an ARM-based STM32F446 USB interface to eliminate digital jitter across high-resolution PCM (up to 1536 kHz) and native DSD1024 playback.
KEY FEATURES & PROPRIETARY TECHNOLOGIES
- 24-Bit Discrete R-2R Resistor Ladder Architecture: Utilizes four sets of 0.005% precision-matched resistor networks to deliver linear, low-distortion digital conversion with natural tonal presentation.
- Resistor-Ladder Preamplifier Volume Control: Rotary encoder controls a dedicated resistor-ladder attenuation network, providing volume tracking without the resolution degradation of lossy potentiometers.
- FPGA Processing & Dual Precision Clocks: FPGA signal processing paired with dedicated 45.1584 MHz (44.1 kHz family) and 49.152 MHz (48 kHz family) active crystal oscillators suppresses timing jitter.
- Extreme Sample Rate Support: Decodes up to PCM 1536 kHz and native DSD1024 via USB and dual I²S (HDMI) inputs, as well as PCM 192 kHz / DSD64 via Coaxial, Optical, and AES/EBU.
- Inbuilt Low-Noise Linear Power Supply: Custom O-shaped transformer with low-noise power management and a vibration-isolating tripod chassis design.
- Fully Balanced Analogue Circuitry: True independent left and right channel output stages available via XLR balanced and RCA single-ended connections.
