PrimaLuna EVO 100 Tube Integrated Amplifier

Overview

The PrimaLuna EVO 100 brings the warmth and dimensionality of a genuine all tube integrated amplifier into a package that anyone can live with. Built around an EL34 push pull output stage delivering 40 watts per channel, it pairs the classic midrange bloom of that celebrated tube with the mechanical quiet and long term reliability PrimaLuna is known for. Point to point wiring, a potted toroidal power transformer, and wide bandwidth output transformers form the foundation of a musical, engaging presentation.

What makes the EVO 100 so approachable is Adaptive AutoBias with the Bad Tube Indicator. There is no soldering, no meters, and no guesswork. If a tube ever fails, the amplifier drops into protection mode and an LED points you to the tube that needs replacing. Swap in a new one and you are back to the music. The included headphone output is transformer coupled and genuinely capable, so a wide range of headphones can be driven straight from the front panel.

With four RCA line inputs, a tape output, an optional moving magnet phonostage, and a slim remote, the EVO 100 works beautifully as the heart of a real music system. At All Elite Audio we love pairing it with high efficiency loudspeakers where those 40 tube watts sing.

Key Features

• EL34 Push Pull Output. The EVO 100 uses a quartet of EL34 output tubes in push pull configuration for 40 watts per channel, delivering the rich midrange and natural tone that made this tube legendary.
• Adaptive AutoBias. Tubes are biased automatically and continuously, keeping the amplifier in its ideal operating range without meters or manual adjustment for consistent sound and extended tube life.
• Bad Tube Indicator. If a tube fails the amplifier enters protection mode and a red LED lights in front of the tube that needs replacing, so maintenance is as simple as plugging in a new tube.
• Point to Point Wiring. The signal path is hand wired point to point rather than using circuit boards, a build approach reserved for the finest tube gear and one that supports long service life.
• Potted Toroidal Power Transformer. A massive toroidal power transformer is potted in a metal housing to reduce magnetic and acoustic noise, keeping the low level detail of the music clean and quiet.
• Transformer Coupled Headphone Amp. A quarter inch headphone output driven from the output stage lets you enjoy true tube sound with a wide range of headphones without a separate amplifier.
• Flexible Connectivity. Four stereo RCA inputs, 4 and 8 ohm speaker taps, a tape output, an ALPS Blue Velvet volume control, and an optional moving magnet phonostage make integration easy.
