iFi Retro Stereo 50 Integrated is a Customer Favorite in Looks and Performance

Now at True Audiophile

At its reasonable price point for an amplifier of its unquestioned versatility and sonic range, we have to give it a nod. While it looks Retro, there's nothing about the inputs that make that statement. Everything from Blue Tooth to USB and beyond... TA

The Retro Stereo 50 turbo-charges your tunes and produces superb-quality audio. It create an old-school yet modern vibe for your living space that reaches quality sonics rather than resting on retro-looks. Really, there’s nothing else like it.

Connect your way.

Whether you stream wirelessly or you’re old school and dig vinyl, the Retro Stereo 50 delivers something fresh.

Connections include:

Bluetooth (aptX)
Stream on your smartphone or plug in your laptop or vinyl player.

Speaks volumes

Accompanying the Retro Stereo 50 are two LS3.5 speakers made from bamboo. And this is not only because it gives them a timeless elegance, but also because organic products rock (in more ways than one!) Bamboo removes distortion and creates a cleaner, more natural sound.

The days of clunky sound bars are over. Connect the Retro Stereo 50 to your TV then experience your much loved shows and movies in crystal-clear clarity.

The tech spec:

It might be compact, but it’s loaded with the latest technology, including:

  • X-Bass+ – To clean up and restore a rich, deeper bass line
  • 3D+ – To recreate the live stage atmosphere


Enjoy your music, your way.

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


True Native® playback of 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. The Signal-to-Noise ratio of the iPhono2 is 3dB quieter on MC and 10 dB quieter on MM than the original iPhono.

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


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.


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

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