LOGO ver1 8

From vinyl all the way to Smart Phones –
your music, your way

Class A bewitching tonality and realism

Octa-DSD512 and PCM/768KHz. Ultimate audio and fully future-proofed

Starting with the Stereo 50, the iFi Retro is a completely new range that has one objective: to include everyone who loves music regardless of age, gender or technology.

The Retro Stereo 50 is an all-in-one tube stereo system: from Bluetooth aptx (phone/pad) to High-res digital (computer) to vinyl (turntable). Everyone can bring their music and be able to connect to the Stereo 50 and produce music that simply astounds. There really is nothing like the Retro Stereo 50.


Music is in the air


Smart devices capable of Bluetooth, aptX (best mode of wireless transmission) and NFC (extreme ease) can be “wirelessly paired” to the Stereo 50. From there, it is a simple case of opening your music app, be it your music collection on your music player, Spotify or Tidal and hit play!

The aptX option offers CD-like-quality wireless audio beyond normal Bluetooth. This means the Stereo 50 is future-proofed for Smart devices for many years to come.

USB & SPDIF for streaming/computer audio


Nowadays, nearly every home is streaming, be it from the set top box, smart device or computer via SPDIF coaxial or the USB 3.0 port. Irrespective of your preferred listening method – from Spotify to J. River; connect to the Stereo 50 and enjoy your favourite tunes at a whole new level!

High-resolution audio (DSD512, PCM768kHz, 2xDXD) via USB, Coaxial and Optical are all catered for. Just connect, sit back and enjoy your music your way.

Space-age digital and classic valve technology


AMR and iFi are renowned for combining classic valve technology with state-of-the-art digital technology such as in the prestigious AMR DP-777 Digital Processor. The Stereo 50 is the latest from a long line of outstanding products. It features 4xEL84X and 2xECF82 tubes with a stunningly advanced ground-up circuit that has DNA from the best of classic amplifiers such as Telefunken, Marantz and Leak.

Running primarily in Class A, its 25W+25W is and sounds astonishingly realistic. This all means a sonic performance that reflects the superb design and implementation.

Burr-Brown brightest chipset + AMR unorthodox technology


At iFi, ‘the best format’ is not the focus. Rather, we care for replaying each format at the pinnacle.

The Burr-Brown DAC chip used was developed by BB Japan (as opposed to BB/TI) though the product introduction was after the merger. Being Burr-Brown’s swan song chipset, it featured their ultimate converter technology and even to this day, is held in the highest esteem.

Having a chipset able to play all formats would count for little if this was not all executed natively, which means no conversion from one format to another. Using trickle-down technology from AMR (who wrote the chipset’s unorthodox control software) to drive this Burr-Brown chipset means preservation of the original music format which is essential for reaching the zenith in high-end audio reproduction.

High-Resolution on PCM768/DSD512/2xDXD

LOGO ver1 8

Computer-audio playback is advancing at breakneck speed. The Stereo 50 on the outside exudes classic retro styling, but on the inside, is at the cutting-edge.

It is able to play all formats to the highest level:
– PCM, from 16/44kHz all the way up to 32/768kHz
– DSD up to Octa-DSD512 (22.6/24.6MHz)
– DXD, 2x to 768kHz

Not only the hyper-advanced formats/sampling rates, but the filters employed also ensure the most analogue and life-like reproduction. The Minimum Phase filter for PCM and Bit-Perfect filter for DXD/DSD ensure maximum enjoyment. These filters ensure the typical “metallic edginess” to standard digital playback is not present, leaving a smooth and organic tonality.


In-Ear & Headphone lovers in for a treat

Got headphones? The Stereo 50 with separate 3.5mm and 6.3mm inputs is just for you. Each headphone input has its own dedicated gain and sensitivity to perfectly match high-sensitivity In-Ear-Monitors and low-sensitivity Over-the-Ear headphones respectively. The 6.3mm output pumps out a “turbo-charged” 7,000mW. So even the most demanding of headphones such as the HiFi Man HE-6 has met its match.

The Stereo 50 features iFi’s widely-regarded 3D Holographic for Headphones® and XBass® technologies. They have garnered a following with their mesmerizing ability to perfectly match each and every type of recording and headphone. The 3D Holographic for Headphones® technology uses pure analogue signal processing which delivers a wide open and spatially correct sound stage for headphones that places the sound field “back outside of the head” to enhance the listening experience. The XBass® technology creates the finest bass and dynamically corrects the bass response to perfectly suit the way we hear.

Vinyl oozes verve


iFi’s iPhono has already become a modern classic and the Stereo 50’s phono stage is set to emulate this feat. It has adjustable ultra-wide gain MM/MC from 38-62dB and its tone control system harks back to classic equalisation technology. With 6 different EQ curves (via the precision tone control), every stereophonic record is catered for. From the default RIAA through to EMI and Decca, as the legion of iPhono users can attest, once dialed-in, each and every record has “a kind of vinyl magic”.

The astonishing EQ feature would count for little if the actual sonic ability of the phono stage was not executed with finesse. Well, just like the iPhono, the Stereo 50 is one of only a handful of phono stages whose noise floor is below (as opposed to above) that of the record. With its superb dynamics and resolution, the Stereo 50 comfortably plays in the big league of vinyl.


Analogue Tone, Volume and Remote Controls

Digital volume controls truncate the delicate audio signal so iFi avoids this at all costs. The Tone Controls, Volume Control (with remote control) are all of extreme high-quality. The critical analogue volume control is by Alps (Japan) motorised potentiometer (< 3dB tracking error).

Audio equipment up to four times the price do not possess a volume control as high-quality as the Stereo 50’s. It is this fastidious attention to detail and highest-quality composition that sets iFi apart: in our sonic mission, we leave no stone unturned.

Retro Stereo 50 + LS3.5, a magical match for audio heaven


The Stereo 50 “full system” including the Retro LS 3.5 is a match made in audio heaven.

The LS3.5 is iFi’s 21st century take on the legendary BBC LS3/5a. To create the LS3.5 speaker, iFi scoured the globe for the very latest technologies and ideal materials. The result is a deep, wide and open sonic signature with spine-tingling tonality.

Swimming completely against the tide, the LS 3.5 (see LS3.5 product page for full details) was designed by iFi for iFi, so you won’t find its drivers or features on any other speaker, regardless of price.

The silk-dome, horn-loaded tweeter (1.1”) and coated natural paper wideband driver (4.5”) were developed in-house. Both drivers were design by iFi and used by iFi which is unprecedented for a mass market speaker.

Its non-resonant bamboo cabinet is both environmentally-friendly and uncompromising in its sonic performance. The cabinet is 3x stronger than wood and yet only half its weight thus not over-damped.

It is perfectly time-aligned and has internal acoustic technology that leaves other speakers lagging behind. Even the internal structure has been finely tuned (sound bar/braces) using musical instrument manufacturing methods.

All this coupled with the Stereo 50’s XBass® and 3D Holographic for Speakers® technologies creates a sonic synergy that is simply out of this world.

Liam from Ireland enjoying the Retro 50!


“Got mine recently as Livingroom system. Very happy indeed. Playing Qobuz mainly via a Kokkia Apt-X Bluetooth adapter from my IPad 2. Very musical. No listening fatigue. No gripes at all in fact.”
Thanks Liam!

“Stereo50 brings out the beauty of the music being played”


“I could immediately hear Dee-dee of Dexter Laboratory say her catch-phrase “Oooooooh, what does this button do?”. So many buttons and switches. Cool! The overall finish is excellent. The cover gives you a peek at the tubes. My first tube amplifier…..The iFi website mentions a study done on the effects of adding tubes to your hifi system. With the Stereo50 I feel I was part of the study and belong to the group where the music invites you to listen longer and influenced your movements such as tapping your feet. I am enjoying my music independent if it is coming from a LP, CD or radio. The amplifier is my introduction to tubes…..somehow it attracts your attention, because the music it makes sounds beautiful. There is definitely a sweetness in the sound…..The amp is very well balanced. You notice this with everything. It is a well thought out all-in-one concept. Everything is not just added and put on top of each other, which maybe would have doubled its price. It is integrated in the real sense of the word. The end result is a very beautiful, sweet pure natural sounding amplifier that successfully combines old and new technologies and offers an extravaganza of music sources to listen to.”

Pros: Sweet pure natural sounding amplifier that successfully combines old and new technologies and offers an extravaganza of music sources to listen to
Cons: it’s hard to think of cons with this kind of performance and high value for money

iFi Retro 50: From the past, to the future!


Zococity (iFi:Spain) has just submitted a review of the Retro 50 from the On Of magazine, here are a few comments;

“….the IFI 50 is equipped with the latest technology in terms of connectivity and digital-analog decoding. The APTX system, beyond conventional Bluetooth ensures reproduction quality equivalent to that of a CD. It is obviously the best deal from our wireless device files flac or wav or even streaming from a provider that offers high resolution (or Spotify Tidal). The built-in DAC prestigious Burr-Brown PCM supports, or DXD, DSD (22.6 / 24.6MHz). To make matters worse, vinyl lovers will also enjoy The IFI Retro 50 thanks to its phono input MM / MC.

Retro 50: “Proved so satisfying”

“A feature of the system the parent IFI retro minimalism and compatibility, and that means that because of the small size of both amplifier that columns can be set anywhere. In addition, thanks to the unprecedented flexibility to handle almost all kinds of digital and analog sources, IFI Retro turns out to be unique. The quality of the sound that I got from different signal sources, proved so satisfying that in order to get a similar effect with separate transmitter and it even supports DSD phono preamp or headphone amp, you have to book far larger amount than the total cost of the system. With unprecedented functionality and mature sound, this system does not despise even the audiophile. Retro Ifi has high value for money – unofficially admit him a six-star rating for opportunities, but our table is provided only five.”

Stereo 50: Journey to the future

“IFI Audio introduces the entire product line with meaningful called Retro…..As soon as I opened the (beautifully prepared) cardboard, almost speechless…..The amplifier itself is also unique. A small, compact enclosure made of natural wood……The amplifier is cool, value for money, remarkable….

LS3 / 5 was small, but the monitor – designed specifically for small spaces as possible…. In LS3.5 there is almost no crossover – bass-midrange is connected “live bait”, without any filtering, and tweeter – by a single capacitor of low capacitance…..On the back you can see a gap opening bass-reflex, a housing divided into two chambers (lower slightly larger), leaving only a very narrow inlets in the vicinity of the front wall. In this way, additional internal resonance systems.

Combining the best of IFI Audio System – D / A converter, phono preamplifier, headphone amplifier with a vacuum tube power amplifier, stylish setting, fine materials…..He can absolutely everything and much more than a standard stereo amplifier.”

“Retro” is fabulous!

“Trust me when I say that ifi’s “Retro Stereo 50” is the best all-in-one amplifier (plus speakers) I have heard in the price bracket of around $2000. It’s a system which utilizes valve technology and offers just about everything you need in the 21st century…..If you are in the market for a small system for your living room or elsewhere, this is really where you should start looking. Chances are that you won’t need to look any further. If I had to start over again, I would start here. The ifi “Retro” systems gets the highest recommendation I can think of! Do check it out.”



“I could not restrain my enthusiasm” says Marc of Hifigasten about the Retro System!

“I could not restrain my enthusiasm. So if you want the short version: the iFi Retro Stereo 50 is a ge-dig device!…..the iFi Retro Stereo 50 has a nice champagne-colored glow and is divided almost perfectly symmetrical. The front panel is therefore very clear and still radiates tranquility…..You can connect the Stereo 50 next to a computer and a turntable also other digital and analog devices…..But where to start? The iFi Retro set offers so many connection and adjustment options…..Morning of the album Beck Morning Phase (2014) resulting from the speakers – the guitar that opens the song has a full, warm sound but is also nicely detailed; every attack on the metal strings is perfect to follow and ‘presence’. The layer has a pleasant pressure at which the switch will be highlighted. The airy character of the Stereo 50 shows the overdubs Beck’s voice beautiful float between the speakers for the ethereal nature of this track added emphasis…..this headphone amplifier we still a shock in a positive way!…..As we said in the intro, “the iFi Retro Stereo 50 is a ge-dig machine!”

“We’ve been talking expectantly about iFi Audio’s Retro Audio System in our reports from the last several trade shows we’ve attended, but now the Retro System has finally arrived……The heart of the system is an impressively full-featured integrated amplifier called the RETRO Stereo 50……The speaker uses two iFi designed and manufactured drivers: a 4.5-inch paper cone mid/bass driver and a 1.1-inch, waveguide-loaded, silk dome tweeter……If you’ve ever wondered what an iFi Micro iDSD would sound like if it had effectively unlimited power for driving headphones, plus the ineffable harmonic rightness of valves, then the Stereo 50 is your answer……If you get a chance, do try to give this system a listen”

Rapid Assessment: iFi Retro!

“Retro Stereo System IFI more than hi-fi system standards because it includes a tube amplifier Retro 50 has integrated advanced encoder and a pair of speakers called IFI LS3 class. Both have certainly bamboo shell…..The sound system is pretty small for demand is ideal for listening to music at the office, bedroom or living room has an area of approximately 15 square meters……Looking at the new amplifier, we understand immediately why the company chose IFI called Retro 50. That is because it is the old picture frame machine, the 1950 has been resized…..IFI Retro Stereo amplifier with loudspeaker LS3 50 Retro IFI sound quality does not surrender. Actual sound quality is always portrayed the true voice of each person “
