A DAC built entirely around the signal

With USB, Bluetooth, and S/PDIF inputs, and support for PCM up to 768 kHz and native DSD512, the GLOW is designed to preserve resolution, transparency, and musical detail from source to output.

Tube vs. Solid State

With a single touch, the GLOW lets you switch between two distinct analog sound profiles. This allows you to perfectly tailor the output stage to the music, headphones, and your personal listening preferences.

• Tube mode: Selected NOS-JAN6418 tubes add natural warmth, texture, and a more relaxed musical presentation, while a carefully designed circuit keeps total harmonic distortion (THD) below 0.8% at maximum output power.

• Solid-state mode: Texas Instruments OPA1612 and OPA1642 precision audio op-amps deliver a low-noise, transparent, dynamic signal path with excellent control and clarity.
  
  

2 W output power

Enough power to confidently drive even demanding headphones.

XMOS USB Interface

High-resolution audio playback with low latency.

ESS SABRE DAC

32-bit / 768 kHz PCM, DSD512, 129 dB DNR.

Balanced

Balanced signal architecture for lower noise, improved channel separation, and greater dynamics.

NOS JAN6418 Tube Hybrid

Built around carefully selected NOS-JAN6418 tubes, the GLOW delivers smooth musical playback, natural warmth, and captivating sound in an ultra-compact form.

Power and control for headphones

A separate power supply for the headphone stage provides the current and stability required to drive both the unbalanced 6.35 mm and balanced 4.4 mm outputs at up to 2 W into 32 Ω.

R-2R network potentiometer

Instead of a conventional potentiometer, the GLOW uses an R-2R resistor ladder volume control made from precision resistors. The volume is adjusted in precise, repeatable steps as the signal passes through precisely defined resistance values. This ensures perfect channel balance, transparency, and detail - even at very low volumes.

Designed to grow with your system

Use the GLOW as a full-featured DAC/headphone amplifier, or connect your own balanced analog source. An optional external linear power supply is also available for audio systems with even higher power quality requirements.

Digital or analog - your choice

The GLOW combines digital inputs for USB, Bluetooth, optical, and coaxial connections. At the same time, a dedicated balanced analog input has been deliberately included, so sources such as turntables, reel-to-reel tape decks, or cassette decks can also be used through the GLOW's headphone amplifier.
