Universal Music’s flagship rooms, NBC’s Emmy-winning Saturday Night Live mix room and a brand-new facility for Steve Miller all run on Linea Research – specified by studio designer Christos “Stos” Tsantilis of MIXBYSTOS LLC.

Linea Research has quietly become the go-to amplification choice for some of the most demanding reference rooms in the United States. Across a growing portfolio of high-profile studios designed and built by MIXBYSTOS, recent installs include Universal Music’s flagship rooms in New York and LA, NBC’s Emmy-winning Saturday Night Live mix room, and a new two-room mix facility for Rock and Roll Hall of Fame inductee Steve Miller – with more on the way in mastering houses and live-event venues.

Led by mix engineer and studio designer Christos Tsantilis – known simply as Stos – whose career has straddled mix engineering and acoustic design for more than thirty years, MIXBYSTOS delivers turnkey stereo and Dolby Atmos rooms, handling acoustic design, the build, immersive system integration and final tuning all in-house. And, increasingly, Linea Research sits at the heart of every project.

The main rooms for Universal Music in New York were designed and integrated by Stos, including the reference Dolby Atmos room where an estimated 3,000 to 4,000 commercial mixes have already been printed. Universal LA followed, and then NBC’s Saturday Night Live mix room – which went on to win the Emmy for Outstanding Sound. A direct recommendation from Universal led to Steve Miller, for whom the team built a new two-room mix facility powered by Linea Research. The amps have since cropped up in mastering work too, including a recently released A$AP Rocky project.

Putting amplifiers through their paces before recommending anything to a client is something Stos takes seriously. Linea Research came out on top on sonic performance, processing depth and – crucially – reliability when the pressure is on. “We always test any units on the market to see which ones we can recommend, and Linea Research came out as the best product in our tests,” he says. “They’re workhorses. The last thing we need is a call-back saying there’s been a malfunction in the middle of a live-streamed event being watched by millions – we avoid that like the plague. Linea Research makes us look good.”

Throughout the company’s portfolio, Stos has paired Linea Research amplifiers with high-end monitoring, offering the option to drive passive components directly via analogue or, run digital in and out where conversion is handled at the loudspeaker. That flexibility, combined with the onboard processing, has made Linea Research the default spec for the company’s most prestigious installs.

When it comes to fixing real-world rooms, the EQ algorithms and the sheer number of filters on offer are a real differentiator, Stos points out. “Not all algorithms are the same. The equalisation algorithm must be musical, transparent and not get in the way – and Linea does an excellent job of representing a truthful, musical sound field. We also have more filters available, which we really need; very few rooms are acoustically perfect. The EQ and time alignment Linea allows us to dial in is one of the main reasons we choose it. It’s accurate, it’s easy to set up, and the clients are always happy. We get called back saying ‘this is perfect’ every time.”

All installs are run through Linea Research’s System Engineer 8 control software, which Stos describes as “very easy” to work with. Pair that with the amps’ plug-and-play simplicity – pick analogue or digital in, tune the system, done – and the workflow benefits really start to add up on tight, high-stakes builds.

Currently, MIXBYSTOS is specifying Linea Research for an 8,000 sq. ft live-streaming, live-event and art gallery venue in SoHo, New York. The amps’ control and processing capabilities were instrumental in ticking the local community board’s boxes around sound levels and New York City code compliance.

“When we walk into a facility and see other products, we let the client know straight away that Linea Research is the way to go,” Stos concludes. “It’s more transparent, more musical, it’ll last longer and they’ll have fewer issues. We’ve never had a client call us to say a unit malfunctioned – ever. When it comes to workflow and stability, that’s why we choose Linea Research, and that’s why we always recommend Linea Research.”
