Features & Specs Line Circle

Quad-stack Burr-Brown DAC design
Uses four interleaved DACs to improve linearity, reduce channel crosstalk, and reveal low-level detail with more convincing depth and placement.
FPGA-powered filtering + DSD remastering
The Crysopeia FPGA provides multiple digital filter choices and enables remastering/upconversion to DSD512 or DSD1024 for those who want a different presentation of transients and ambience.
Three analogue “voicings” in one unit
Toggle between discrete Class A solid-state and tube-based output stages, or engage Tube+ for a more harmonically rich, fluid presentation—without changing hardware.
Plays virtually any modern hi-res format
From mainstream lossless to extreme-res files, it supports PCM up to 768kHz, DXD/2xDXD, DSD1024, and MQA—ideal for library collectors and streaming services alike.
Streamer + DAC + preamp flexibility
Run it as a standalone DAC, a DAC/preamp into power amps, or a network endpoint over Wi-Fi/Ethernet via DLNA/UPnP and AirPlay, with local playback from attached storage options.
Balanced, system-ready output control
Choose fixed or variable output on XLR/RCA, select Pro/HiFi output levels, and use the motorised Alps volume control with IR remote for precise, repeatable listening levels.
