No compromises, shown
Section titled “No compromises, shown”The s1 is the one player we make, so it gets everything: the best DAC chip we can offer, a body milled from one block, and a measurement report for every unit. Nothing is cheaper inside than outside.
- Measured, one by one: every s1 is measured at its XLR outputs before it leaves us, and its report comes in the box. Not a datasheet value, your unit.
- Milled from one block of aluminium: no seams, no visible screws. Only the base plate comes off. Every part is mounted into the body from below.
- A closed chamber for the audio: the DAC, its clocks and the output stages sit in their own chamber, milled from the block, apart from the computer side. Nothing that switches lives next to the DAC.
- Built to order: in small batches, in the black series. Aluminium on request.
The sound
Section titled “The sound”- ESS ES9039PRO, all eight channels used, four per stereo channel, fully differential to the XLR outputs.
- The DAC sets the clock: two femto-class oscillators, one per sample-rate family, right at the DAC, and reclocking after the digital isolator that separates audio from computer.
- A clean supply: one certified medical-grade supply outside the case; inside, an isolated supply for the audio side and ultra-low-noise regulators per rail.
- Native DSD up to DSD512, PCM up to 384 kHz and 32 bit, bit-perfect: every file reaches the DAC unaltered at its own rate, and the s1 shows it.
The object
Section titled “The object”- An 8” touch display on a 45° slope, bonded to black glass, with the native bitwerk interface: readable from the sofa and from standing.
- One knob: a haptic smart knob with detents set in software. Turn for the level, press to mute.
- The cube is the play key: it glows green for bit-perfect, white when the sound is processed, yellow for a warning and red for a fault. Press it to play or pause.
- Silent: no fan. The heat goes straight into the block.
- 265 × 165 × 96 mm, floating on a dark shadow-gap foot.
One box, a whole system
Section titled “One box, a whole system”The s1 holds the library and plays it: plug in a drive, or put one inside on its M.2 slot, and it reads the tags, sorts the albums, finds the covers and plays. Run it from its display, its knob, the bitwerk app or any browser; no computer has to stay on.
Add rooms and storage
Section titled “Add rooms and storage”- m1, for every further room: a small player without a screen, over Ethernet, that plays in sync with the s1. In design. See the m1
- b1, when the library grows: a rack unit that holds large libraries for every player in the house. In design. See the b1
With the bitwerk h1 in the living room it is one system.
What we left out, and why
Section titled “What we left out, and why”- Wi-Fi and Bluetooth: nothing that radiates sits next to the DAC.
- HDMI: a TV connects optically.
- Infrared and a remote: the s1 is run from its knob, its display, the app or a bitwerk c1.
- A fan: the block is the heat sink.
