SAM®
Pure emotion. Extreme fidelity. All your music, just as the artist intended.
SAM® Speaker Active Matching works by recognizing the exact specs of your speakers. So Expert Pro can tailor the sound signal to fit their precise requirements. In real time. A major audio breakthrough, SAM® lets your system achieve perfect temporal alignment between the recorded signal and the acoustic pressure generated by your loudspeakers. For the first time ever.
SAM® is an electro-acoustic revolution. For the first time ever, Devialet SAM® technology guarantees a seamless match between your amplifier and connected speakers. Almost all multi-way loudspeakers generate delay caused by the bass diaphragm reacting slower to the audio signal than the tweeter does. Mechanical and technical measures help to minimize delay that would otherwise disrupt the evenness and spatial quality of sound. Preliminary laboratory work carried out via SAM® Lab enables us to identify sixty or more different parameters per speaker model.
SAM® analyze's transducer characteristics using laser technology. These include displacement, deformation, maximum displacement, speed and acceleration. By measuring passive filters, we can determine resonance (event bass-reflex and passive radiators) while factoring in the overall impact of casing and damping. Once this data is compiled, SAM® is able to produce a full physical behavioral model. The collected data also allows us to calculate the transducer SOA (Safe Operating Area). By doing so, SAM® offers permanent protection from overload, letting users reach higher volumes than ever before.
Similar to transfer function, this physical model is inverted in real time using digital signal processing technology before digital-analogue conversion occurs. The result: acoustic pressure in the air perfectly matches the signal registered by microphones during the recording process.
Pure emotion. Extreme fidelity. All your music, just as the artist intended.
+1000 NUMBER OF SAM-READY SPEAKERS
+96000 inspection points per seconds REAL-TIME SPEAKER PROTECTION
Up to one octave depending on the model BANDWIDTH EXTENSION
A temporal process, SAM® runs on an open loop and without sensors. No changes to set-up are required. The process is strictly causal and generates no pre-echo.
Playback is radically enhanced, with considerable gain in spatial coherence and transparency (each transducer delivers optimal performance). Your speaker model’s unique specs and character remain intact. By recognizing the functional limits of each speaker, SAM also allows for further extension into low-range frequencies.
Your speakers are transfigured.

Devialet, SAM, and the Changing of the High-End Guard
"Because the Devialet 120 with SAM sounded so good with the diminutive S1s, I figured I’d try it with Magico’s enormous Q7s, a pair of which sat in the background in my room. I’ve struggled a bit to find appropriate amplification for the Q7s. I’ve tried numerous amplifiers, and up to this point the best partner for them had easily been Gryphon’s Mephisto -- which costs $57,000. Nothing else I’d tried had been as satisfying."
"Until now."
"Would you believe that the best match I’ve heard for the $185,000/pair Magico Q7 is the $6495 Devialet 120? I know -- hard to fathom."
"I could not believe my ears. The Q7s’ bass was now superior to anything I’d previously heard from those speakers, in my or any other room. It was the most profound bass I’d ever heard, period. Like nothing I’d experienced before, the Q7s were energizing my room and my entire house. As she ate her breakfast downstairs in the kitchen, my nine-year-old daughter thought something was seriously wrong. It was crazy. The bass was articulate, as tight as a drum, punchy, weighty, with slam galore. I could hear everything, with absolutely no hint of boom or bloom, but also with no dynamic constraints. It soared and plummeted and moved me. Again and again. I just sat and listened."
"And then I did what any audiophile would do: I played album after album, from many artists working in many genres, reveling in this newfound high fidelity. Could it really be sounding this good? This is not a review per se, so I won’t give you a blow-by-blow, track-by-track account. What I can tell you is that I’d never heard music sound this good in a home. As I write this “Opinion,” I’m blown away by the implications of the effects the Devialet 120 will have on my listening and the writing that I will do from now on about other products. The phrase is too often carelessly used, but for once it’s an accurate description: It’s a paradigm shift."
"The bottom line: The Devialet 120 -- with its paltry 120Wpc into 6 ohms and its price of $6495 -- was a great match for the Magico Q7s, whose cost matches their size: $185,000/pair."

SAM® Speaker Active Matching technology -
"Addressing a fundamental problem of loudspeaker bass behaviour, the SAM system is a new way of correcting transducers in the lower frequencies. A truly exciting and spectacularly effective device, it is one of the most musically intriguing I have encountered in many a year. The problem of correct bass timing in speakers has been known for a very long time—decades really. But addressing it was a difficult matter in a purely analogue world. In the DSP world, things are different. The details of all this will require some explanation, and, in fact, there are aspects of this device that I have not yet been able to clarify completely in technical terms. But in listening terms, the results are remarkable."
"Technologies like SAM that monitor the speaker’s behaviour and correct that behaviour on the fly seem to me the way to progress even beyond the almost miraculous performance of the best passive speaker designs. I am still working on what exactly SAM does in measurement terms. But I can tell you for sure SAM sounds fabulous and, perhaps more importantly in the long run, represents to my mind what is needed in audio. It has been more than twenty-five years since I first started writing about the marvels that DSP devices would produce in audio. Wonderful they were and are. But they are static—they do what they do without concern for what the speaker is actually doing except to the extent that this is embodied in linear system measurements (frequency response and phase response). But the Devialet SAM system goes beyond in its dynamic signal-following behaviour. It was time for the next big step. And here, I think, it is."
