Twelve years after its original introduction, the Sonorus Audio ATR10 has been updated with the latest insights in sound reproduction and technical performance and is now called the ATR10 mkII.
Although at its core it's still based on proven Studer motors and heads, all electronics and many mechanical parts have been redesigned to meet and exceed any modern day high-end and audiophile expectations. Regulated tape tension and strategically-placed rolling tape guides provide the same stable tape transport as professional studio tape machines.
Vacuum tube playback electronics utilizing the unique, newly-developed DC Coupled Stabilized Loop Gain Technology delivers a remarkable combination of dynamic bass impact, normally only associated with solid state systems, with the mid-range clarity, transparency and sense of realism of vacuum tube systems.

Redesigned Electronics ◦ Modern Mechanics ◦ Advanced Performance
The ATR10 mkII masterfully marries modern circuit design with classic analog to produce a playback performance with a minimum of electronic coloration. To ensure the deck remained true to original recordings, the deck has a integrated a novel amplifier control system. Four new old stock Philips manufactured ECC88 tubes, expected to last more than 10,000 hours, work in tandem with the DC Coupled Stabilized Loop Gain Technology. This blend results in dynamic bass impact, combined with enhanced mid-range clarity and the rich transparency typical of vacuum tube systems.
While this is a feature shared by many pro-decks, few approach it by the way Arian has. Arian’s goal was to exceed the tape regulation of the Studer A810. He used that as the reference to improve upon. To avoid using mechanical tape tension arms or tension gauges along the tape path, he opted to regulate the tape tension by measuring the speed of rotation of each spool to ensure consistency of tape over the heads is the same at the beginning of the tape as it is at the end. This ensures a consistently low wow & flutter over the entire tape. This also simplifies the deck's mechanics.
Proper storage of prized tapes is facilitated by the library winding feature, which gently winds the tape under optimal tension. Motor-assisted braking results in very fast braking times and streamlines fast-forwarding and rewinding.
The deck is designed to sound superior when new, but to maint its quality sound a decade down the line. Using insights from his early career, Arian Janson fashioned circuitry to perpetually gauge head wear and automatically compensate for it, ensuring consistent sound performance over time.
Decks with this design, even after 12 years, have shown to remain within 95% of their original spec—a testament to Arian's 30+ years of expertise in electronic circuitry simulations. As Arian remarks, “while simulations don't inherently enhance sound, they do bolster reliability and predictability”.
The mkII proudly features genuine, new old stock Studer heads. These are not new heads based on the Studer design, these are actual new Studer heads. Every mkII sold will include a new, original Studer head, while supplies last.
Users can bid farewell to concerns about perfectly matching hub adapters. The ATR10 mkII comes equipped with built-in ones, ensuring tape balance and centered positioning.
The ATR10 mkII incorporates a feature that in combination with SHI tapes halts the tape at the start of the music program after rewinding—an undoubtedly handy addition.
Sonorus Audio offers a unique analog remastering service. Most existing stereo or multi-channel albums can be remastered to a master tape format in a fully analog process designed to unpack the sonics that are typically lost in the commercial record making process. The result is expanded soundstage and increased dynamics typically found in live performance miking.

ATR10 mkII customer John Berg said it best...
⭐⭐⭐⭐⭐
"It's a complex playback machine with a simple design. The tape path is easy and it's really quiet mechanically. Most Important is the sound quality, its stunning. Its lush, but not overly bloomy. It's accurate, but not offensive. It's warm but not colored. It's lively, but not aggressive. It's silky, but not frail or weak. I think, in many ways, it's the best "all-around" deck I own"
