Gustard R30 – DAC + Streamer

Description

Gustard's flagship — Absolute precision, analogue soul

El Gustard R30 it represents the pinnacle of the brand's expertise:
A DAC discrete reference R2R, with Ethernet streamer,
passive preamplifier with R2R control using relays,
and one Class A output stage of purely discrete construction.

All of this housed in a heavy-duty, machined aluminium chassis,
powered by dual toroidal transformers and governed by a OCXO clock of extreme precision.

The result is a sound organic, three-dimensional, powerful and natural,
able to rival Western models at more than double the price.

⚙️ Architecture and design

• Conversion proper discrete R2R, with ultra-tight tolerance resistor networks.

• Digital processing by Dedicated FPGA → controls clock, PLL, filtering and PCM/DSD modulation.

• Native DSD decoding from 1 bit real (up to DSD1024) y PCM 32-bit / 1536 kHz.

• Output stage totally discrete in class A (without operational amplifiers).

• Clock High-stability OCXO + module GCLK-02 PLL → practically zero jitter (≈1 Hz).

• Power supply independent dual toroidal (digital + analogue).

• Machined aluminium chassis, rigid and ventilated, black or silver finish.

An impeccable execution where engineering, precision and musicality go hand in hand.

🌐 Connectivity and features

Digital inputs:
LAN (Ethernet 100/1000 Mbps),
2 × I²S HDMI,
USB-B, AES/EBU, Coaxial, Optical,
10 MHz BNC input (for external master clock).

Analogue outputs:

• RCA: 2.5 Vrms / 100 Ω

• XLR: 5.1 Vrms / balanced

Supported network protocols:

• Roon Ready

• AirPlay

• UPnP / DLNA

• HQPlayer NAA

• Spotify Connect

⚠️ Tidal Connect and Qobuz Connect are not integrated, but are accessed via Roon or UPnP.

Control and management:

• Intuitive web interface with one-click updates.

• Analogue R2R volume control with precision relays.

• “Bypass” mode for use with an external preamplifier or integrated amplifier.

🎧 Sound and character

Selectable digital filters:

• Crisp linearmaximum precision and attack.

• Slow Minimumnatural and relaxed tone.

• Super slowwarm, analogue sound, vinyl or valve style.

The R30 achieves a perfect balance between R2R musicality and reference-level resolution.
It is fast, refined and deeply human.

🔌 Preamplifier mode

• Volume control passive relay-switched R2R analogue.

• It can be connected directly to power amplifiers or active monitors.

• It offers no additional profit (pure passive previous).

• Mode Bypass/Fixed available for integration with external preamplifiers.

It allows a direct and transparent connection, without adding coloration or compression.

🖥️ Integrated streaming

The R30 incorporates a complete streamer via Ethernet network,
based on a optimised Linux kernel and developed in conjunction with CelWare.
Its system eliminates unnecessary processes, reducing latency and digital noise.

It can completely replace dedicated mid-to-high-end streamers.
like Lumin, Aurender or Volumio Rivo Plus.

Requires direct Ethernet connection for maximum performance.
