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.”

Retro 50 featured in Haute Fidelité (French) magazine

Verdict: iFi Audio managed a great achievement, both for aesthetics as for the technical design. Rarely will a boombox played at this point the role of bridge between the hi-tech and vintage, with admirable relevance, as ergonomics and audio performance. A try!”

Retro coolness at vintage pricing

My first tube experience in many years!……Hour after hour, day after day, the combo of the Stereo 50 and LS3.5 speakers provided me with clear and balanced sound……So what is my overall sound impression of the Stereo 50 and LS3.5 system? Balanced, controlled, and neutral……What do you want to plug in? Your PC or Mac? No problem! Stream music from your phone via Bluetooth? Done! CD player, DVD player, or Blu-ray player? Check, Check and Check. What about pure analog? You know who you are. Dusting off your old turntable and record collection? The iFi Audio Stereo 50 has an extensive collection of refinements for virtually any turntable you choose to connect……So how do I wrap up my experience with the iFi Audio Stereo 50 and LS3.5 speakers? Well, I was sad to return them and miss having the ability to listen to virtually any source, in any format, at any time.

The Retro Stereo 50: ‘olde + new fusion, iFi just knocked it outta the park’

Sean Fowler of Zero Fidelity kindly made a very comprehensive overview/review of the Stereo 50.

Hop skip and jump to 9.10 if you wish to get to the crux of the review. We can only concur the Stereo 50 is ‘fun, fun, fun.’ Listening to it just puts a smile on your face. J

ps: we loved the fact that the headphone section was noted for being a big hit. Yes, the HE-1000 absolutely sings (swings?) with the Stereo 50
