🔊 Fully Balanced R2R DAC Decoder + Linear Power Supply Combo
Original price: €234 → Now only: €130

(1) Fully Balanced R2R DAC Decoder
Well-maintained R2R DAC in good working condition, with minor signs of use.
It features dual precision resistor arrays (0.01% tolerance) for true balanced output, delivering refined detail, spacious soundstage, and strong dynamics.
Key Features:


Clock System: Low phase-noise TCXO crystal oscillator (0.1ppm precision)
Power Design:

3× TPS7A series regulators for ultra-low ripple (µV-level)
Separate power rails for op-amp and decoding array
4× custom op-amps (no grounding or replacement needed)

Sound: Smooth, detailed, dynamic — a refined R2R sound signature
Audio Support: Up to 24bit / 192kHz
Outputs: XLR balanced / 4.4mm balanced / 3.5mm / RCA
Inputs: Coaxial and USB (interchangeable USB interface cards; compatible with XMOS and Italian USB cards)

Specifications:


Size: 120 × 103 × 38 mm
Weight: 345 g
Power Input: DC 9–18V (recommended 12V, DC2.1 connector)

⚠️ Note: This is a pure decoding DAC, so volume must be adjusted via an external headphone amp or amplifier.
R2R DACs are sensitive to power supply quality — a linear power source is highly recommended for best sound.

(2) 24W Linear Isolated Power Supply
Matching linear power supply, also with light signs of use.
Dual isolated outputs for clean and stable performance.
Specifications:


Max Power: 24W
Outputs:

12V / 2A
5V / 1A–1.5A

Fully isolated design minimizes noise and interference.

(3) Included Accessories


DIR9001 Coaxial-to-I2S USB card (24bit / 192kHz, compatible with Italian DAC interface)
Isolated USB sub-card output (I2S interface, Italian interface compatible)

Condition: Used, in good working order (minor cosmetic wear)
Package: DAC + Linear Power Supply + USB Interface Boards
Price: €130 total
Ideal for audiophiles seeking balanced R2R decoding, clean linear power, and a refined, musical sound at a great value.
