Retro Stereo 50

Looking for a one-box unit with classic styling?

The Retro Stereo 50 is classic hi-fi quality fused with contemporary tech in a compact, retro package.

A timeless modern classic

The Retro Stereo 50 (and LS3.5 bamboo speakers!) create an old-school yet modern vibe for your living or office space.

Classic, compact and cutting-edge, it’s an integrated stereo tube (valve) amplifier with a hybrid output stage and an output of 25W per channel.

All mod cons

As well as analogue inputs including an excellent phono stage to connect a turntable, it incorporates a hi-res DAC with digital inputs to play music from computers and smart devices.

And there’s Bluetooth, too, for those who prefer to stream wirelessly from their smartphones and tablets.

Superior sonics

We’ve also added our signature sonic ‘optional extras’.

XBass+ cleans up and restores a richer deeper bass line.
3D+ helps to recreates the spaceness of a live stage performance.

Adjust bass and spatial performance with ease as all signals are processed in the analogue domain.

Pitch perfect

Listen via your favourite headphones.

Or add a pair of connected speakers. Our LS3.5 bookshelf speakers are designed specifically to go with the Retro 50.

Whatever you choose, you’ll be immersed in gloriously rich, pitch-perfect, expressive sound.

Enjoy your music, your way.

Stream from your set top box, smart device or computer via S/PDIF or USB port.


Hi-Res True Native® playback for all music formats from MP3 to DSD512, PCM768 and 2xDXD.


A class act refined. Every nuance defined. All-new Burr Brown Soundplus® J-FET type amplifier now beats at the heart of the Class A TubeState®.

This new circuit significantly reduces the loading seen by the main amplification circuit which improves the circuit inherent linearity while allowing it to drive even punishing 600 ohm studio inputs with impunity. The power supply filtering has been increased 5X in value.

More than ever, one can hear ‘into’ the recording itself with the blackest of backgrounds and every nuance, inflection is picked up by the system.


The 3DHolographic+® for speakers takes high end systems to another level.

It corrects spatial distortions and increases the width of the soundstage beyond that of the speaker placement.


XBass+® for speakers. No degradation in sound quality.

Provides adjustable levels of bass control to enhance listening enjoyment through speakers that have limited bass extension.

Reviews

iFi Audio Retro Stereo 50 Review

“…the Retro Stereo 50 is one of the most beautiful integrated tube amplifiers on the market.”

“you can see how much iFi Audio care about every detail simply by opening the Retro Stereo 50”

“Not only does the Retro Stereo 50 offer a lot of input options, but it also has many built-in features including a phono pre-amp for both moving magnet and moving coil cartridges, a digital-to-analog converter (DAC), and a headphone amp.”

“The mid-range is upfront and present which adds a beautiful clarity and enhances the sound stage. The highs are a little bright, especially with the LS3.5 or other bookshelf speakers, however, with the tone control, you have the ability to dial this back if necessary. Overall, the Retro Stereo 50 is extremely well-balanced and will be great for listening to your favorite vinyl, digital audio, or even Bluetooth playback.”
