An all-tube line-level preamplifier from PrimaLuna's EVO range. The EVO 100 has four RCA inputs, a motorised ALPS volume control, two 5AR4 rectifier tubes and a slim remote control. It has no internal DAC.

PrimaLuna says all of its preamplifiers use a dual-mono design, so each one is two preamplifiers in one chassis, with tube rectification and point-to-point hand wiring. PrimaLuna builds the chassis from heavy-gauge, fully vented steel with a five-coat finish, each coat hand-rubbed and polished.

This listing offers Black and Silver finishes, with a choice of no phono stage or an MM Phono Stage. PrimaLuna says an MM PhonoLogue board is an optional extra for the EVO preamplifiers.

Why you will love it

Dual-mono, tube-rectified design

PrimaLuna says all of its preamplifiers are dual mono, which means two discrete preamplifiers in one box with separate power transformers for the left and right channels. It says this is where the imaging comes from.

The EVO 100 uses two 5AR4 rectifier tubes. Its tube complement is 2 x 5AR4, 2 x 12AX7, 2 x 12AU7. PrimaLuna says its Silver Label tubes are pre-selected using its 60 out of 100 rule.

Relay input selection and motorised volume

PrimaLuna says input selection uses sealed relays mounted at the rear, where you plug in your sources, instead of a front-panel switch. It says only the selected relay closes, so the other inputs are left open.

Volume is a motorised ALPS potentiometer. PrimaLuna describes it as the ALPS Blue Velvet and says it tracks well and stays quiet.

Hand wiring and protection circuits

PrimaLuna says the signal path, including the resistors and capacitors, is hand wired point to point with heavy-gauge cable.

Its SoftStart circuit is there to extend the life of sensitive parts and reduce the chance of tube failure from thermal shock. Each power transformer has PTP (Power Transformer Protection), a thermal switch that opens the primary if the transformer overheats. The main outputs are muted for 60 seconds while the tubes warm up.

Low gain

The EVO 100 has 10.8 dB of gain. PrimaLuna calls its low-gain approach SmartGain and says it keeps noise down, because a preamplifier is usually lowering the level from the source rather than adding to it.

The input sensitivity for rated output at maximum volume is 580mV.

Connections

Inputs: 4 pairs stereo RCA. Outputs: 1 pair RCA tape, 2 pairs stereo RCA.

Remote control and phono option

The slim remote controls source selection, volume and mute. PrimaLuna says its remotes are made of heavy metal.

PrimaLuna says every EVO preamplifier has a 100% shielded phono chassis on the bottom plate for its optional MM PhonoLogue board. The board takes the place of the AUX 2 input. PrimaLuna says the preamplifier has no internal DAC and no phono stage as standard.

Is it right for you?

A great fit if you…

Want a tube preamplifier with a dual-mono design
Already have, or plan to buy, a power amplifier
Have up to four line-level sources

Worth knowing

Weighs 14kg and measures 405 × 280 × 190 mm (L × W × H)
It is a line-level preamplifier, so it needs a power amplifier and speakers
Optional MM phono board takes the place of the AUX 2 input
Tubes wear out. PrimaLuna gives 5,000 to 10,000 hours for the 12AX7 and 12AU7 tubes as a guide
Switch off and unplug before changing tubes or fuses

Build your system

A preamplifier needs a power amplifier and speakers.

Power amplifier: Add a PrimaLuna power amplifier such as the PrimaLuna EVO 100 tube power amplifier, or browse power amplifiers.
Phono: For records, see the PrimaLuna EVO 100 tube phono preamplifier and our turntables.
Digital: Add the PrimaLuna EVO 100 tube digital to analogue converter for digital sources.
Compare the range: Also see the PrimaLuna EVO 200 tube preamplifier, PrimaLuna EVO 300 tube preamplifier and PrimaLuna EVO 400 tube preamplifier.
