Harmony DAC 2
Hard to find. Hard to replace. Now harder to beat.
The Harmony DAC put LAiV on the map: a fully balanced, discrete R2R ladder DAC that brought organic, natural sound to listeners who refuse to compromise. The Harmony DAC 2 keeps that heart and rebuilds everything around it. This is not a new direction. It is the same direction, taken further.
Already own a Harmony DAC? An upgrade kit is coming. Register your interest and we will keep you first in line.
Discover the highlights.
Both outputs, all the time
A discrete Class A buffer drives XLR and RCA concurrently, at low output impedance.
Direct 10MHz clock input
Connect a master clock straight in. No DDC, no I2S detour.
A new face
960 x 400 colour display with refreshed graphics, readable from across the room.
Your conversion, your choice
NOS, in-house OS, or hardware SRC for PCM. DSD is converted to multi-bit for the R2R ladder.
Isolated in, isolated out
Full digital isolation between input and output. What crosses is the signal.
Lives in your rack
12V trigger, in and out, wakes it with your system. Firmware updates over USB-C.

WHAT CARRIES THE SOUND
CONFIRMED UPGRADE LIST · AUG 2026
XLR + RCA
BOTH, ALL THE TIME
Discrete Class A output buffer
The original asked you to choose between XLR and RCA. A newly developed discrete Class A output buffer drives both analogue outputs concurrently, with low output impedance that holds its composure into any integrated amplifier or preamplifier.
Feed multiple downstream devices at once: your integrated amplifier on XLR, a preamplifier or a second system on RCA. The buffer keeps the ladder isolated from the load, so what you hear is the ladder, not the cable behind it.
NOS / OS / SRC
PCM, YOUR CHOICE
Your conversion, your choice
Pure NOS for the most direct path, LAiV’s in-house OS mode, or a dedicated hardware sample rate conversion stage that is new to the DAC 2.
These modes apply to PCM. An R2R ladder cannot read a 1-bit stream, so DSD is converted to multi-bit before the ladder renders it to analogue.
Which is right depends on your recordings and your system, not on a hierarchy we impose. One DAC, three ways to meet your library.
10 MHz
NO DDC REQUIRED
Direct 10MHz master clock input
The Harmony DAC 2 accepts a 10MHz external master clock directly — BNC, 50 ohm — with no DDC and no I2S detour required. Precision timing is the quiet foundation of natural sound.
If you run a master clock, connect it and the entire conversion process disciplines itself to your reference. If you do not, the DAC 2’s internal clocking carries on the Harmony tradition of getting timing right on its own.
In | Out
FULLY ISOLATED
Isolated in, isolated out
The Harmony DAC 2 places full digital isolation between its inputs and outputs, breaking the electrical path that noise would otherwise ride from your source into the conversion and output stages. Ground loops, USB bus noise, and upstream interference stop at the barrier.
What crosses is the signal. What does not is everything else: a lower noise floor, a blacker background, and more of the low-level detail that makes music feel alive.

LCD · 12V · USB-C
A new face, and every detail behind it
The 16-level grayscale OLED gives way to a 960 x 400 colour display with refreshed graphics: input, mode, and sample rate read clearly from across the room, in a design language that matches what is happening inside the chassis.
Behind the new face, the everyday details are rethought too. A 12V trigger — in and out — lets the DAC 2 wake and sleep with the rest of your system. And firmware now updates over a dedicated USB-C port. Download, connect, update — no ceremony.
A note on availability
FIRST RUN · VERY LIMITED
The first batch of the Harmony DAC 2 is built and ready to ship. Outside the USA, order now and your unit leaves us within 3 to 5 business days. For our US customers: our USA shipment has landed in the United States and is expected to arrive at our fulfillment center in California in 1 to 2 weeks. All new US orders will ship out as soon as the stock arrives at the fulfillment center. We appreciate your patience and understanding. A high-end R2R ladder DAC like the Harmony DAC 2 is never built at scale, and the components behind this one make that especially true. The first run remains very limited. If the DAC 2 is the heart your system has been waiting for, we recommend not waiting.
