A digital-to-analogue converter with a tube output stage and a tube-based data clock. The PrimaLuna EVO 100 has USB, AES/EBU, coaxial and optical inputs and plays PCM up to 24-bit/192kHz and DSD64 to DSD128 over USB.
PrimaLuna builds the EVO 100 with a Burr-Brown PCM1792A converter, dual-mono tube stages and a tube-rectified power supply. A slim remote is included.
It outputs through stereo RCA, so it connects to a preamplifier or integrated amplifier.

Why you will love it
SuperTubeClock
PrimaLuna calls it the world's first tube-based data clocking device. A low-noise mini-triode vacuum tube is built into the digital clock.
PrimaLuna says this gives more resolution, detail retrieval and clarity from top to bottom.

USB input
PrimaLuna says it searched for the best-sounding USB interface it could find. The USB input converts the signal to S/PDIF before it reaches the SuperTubeClock.
USB plays PCM up to 24-bit/192kHz and DSD64 to DSD128 using DoP. The other inputs play PCM up to 24-bit/192kHz and DSD64 using DoP.
Dual mono tubes and tube rectification
The EVO 100 has dedicated tubes for each channel. PrimaLuna says its tube-rectified power supply includes eleven separate power supply regulation circuits.
A 24-bit/192kHz upsampler (Texas Instruments Burr-Brown SRC4192) sits ahead of the Burr-Brown PCM1792A converter.


Premium parts and wiring
The EVO 100 uses polypropylene coupling capacitors, triple-pi power supply filters and custom isolation transformers that separate the analogue and digital sections. PrimaLuna also fits its AC Offset Killer circuit, designed to lower transformer noise.
The signal path is point-to-point wired, including resistors and capacitors.
Is it right for you?
A great fit if you…
- Want a tube-output DAC for a computer, streamer or CD transport
- Use a PrimaLuna or other tube preamplifier or integrated amplifier
- Play high-resolution PCM or DSD files
- Prefer a remote-controlled DAC
Worth knowing
- It has digital inputs only: USB, AES/EBU, coaxial and optical. There is no built-in streaming or Bluetooth
- The output is stereo RCA, so you need a preamplifier or integrated amplifier
Build your system
Connect it to an amplifier, then add speakers.
- Integrated amplifier: Use the RCA output into the PrimaLuna EVO 100 Tube Integrated Amplifier or another integrated amplifier
- Preamplifier and power: Pair with the PrimaLuna EVO 100 Tube Preamplifier and the PrimaLuna EVO 100 Tube Power Amplifier
- Speakers: Choose floor-standing speakers or bookshelf speakers
