Innuos has designed an exclusive 100 units Special Edition aimed to take your music to new heights.
With a new Triple-Linear PSU designed by Sean Jacobs, custom-wound toroidal transformer and a raft of improvements on EMI shielding and vibration isolation, the ZENith SE picks up the trademark PRaT (Pace, Rhythm and Timing) and neutrality of the ZENith and adds more body to the music, improving the depth and height of the soundstage.
Attention to detail that makes a difference
A number of improvements were added for this Special Edition:
• New oversize, custom-wound audiophile toroidal transformer with 3 independent outputs for each Linear Power Supply
• New Triple-Linear power supply designed by Sean Jacobs
using high-end Mundorf caps
• Three anti-vibration feet with asymmetrical positioning to better isolate vibration without a ecting dynamics
• Audiophile-grade silver-coated and shielded cabling for internal connections, hand-soldered directly to circuits to lower impedance from connectors.
Powered by innuOS
As all other ZEN MkII, the ZENith SE is powered by innuOS – Innuos’ own operating system developed in-house. It enables a complete computer-free operation for managing CD ripping, importing digital music and editing album data and cover art.
Recently added features on innuOS version 1.2 include the ability to playback music stored on an external NAS and the possibility of using it as Roon Core Server or Roon Player.
"It is a matrix-like gestalt. Takes two seconds once you find it," my notorious muse Herb Reichert once said to me (in a context I can no longer recall.) But these precise words came into focus as soon as I heard the system in the Well Pleased Audio Vida room. Throughout the entire show weekend, I had encountered many sonically and aesthetically pleasing rooms—with prices ranging from the affordable to the aspirational—that would have satisfied me for years on end. But this…this was something else. In the moment, and in thoughtful retrospect, this system was my favorite of the whole show...
"That's the Allegro in a nutshell: a thoroughly modern, properly engineered amp that's environmentally conscious, quiet like a tomb, utterly unfussy, of high resolution, low distortion and demonstrably potent drive to net very refined sonics. Listeners into deep space—shorthand for their enjoyment of maximally revealed venue ambiance aka recorded space—will find the Allegro twins their perfect tour guides. After VW's diesel engine debacle, made in Germany returns to its golden roots with LinnenberG's Allegro for honest engineering & class-leading performance."

Room 504...we look forward to seeing you there!
"ALLEGRO delivers the superiority and authority of a linear class AB amplifier - even in demanding applications. It features high current capability and operating speed not to be found in IC-amplifiers aka “gain-clone” or any class D design."
Clever construction techniques enabled us to build an amplifier with high packing density, consequently making the signal and power paths extremely short. So, don’t be fooled by the tender look – it is part of the concept to get big sound. In fact, creating circuits with unrivalled speed and response time is amongst other things a matter of physical closeness of electronic parts. The higher the frequency, the more it is important to reduce every millimeter of board trace.
It is the fast transient ability and ultra wide band (1MHz unfiltered) approach that let you hear the room, the ambience of the sound recording. Matching phase coherent speakers assumed, a pair of ALLEGRO amplifiers will deliver a perfectly executed sound-stage. Furthermore, our concept has an order of magnitude lower distortion than competitors in the market. Distortion masks the integrity of the music, because it adds spectral components which weren’t there previously.
Lateral MOSFET output stage
The transistor originally developed by Hitachi in 1977 is probably the only semiconductor power device solely made for audio use. Famous for its tube like characteristic and perfect bias stability under any load conditions, the ALLEGRO uses just a single pair of tandem devices in the output stage in the so called “common source” arrangement.
Balanced signal path
Almost any LINNENBERG (past / future) product features true balanced circuits and connectivity. Historically, this may have a reason in our roots lying in professional audio. ALLEGRO is no exception: here, the circuit composes of a very low noise instrumentation amplifier such as used in high-precision measuring equipment. This approach ensures perfectly matched input conditions for the positive and negative signals and thereby allows the realization of high-performance balanced signal transmission.
Ultra wide band design
The high quiescent current design of all preamp and driver stages enables a core speed close to 1MHz, slowed down only by input and output filtering to match real word requirements. With filters in place, the small signal as well as full power bandwidth (!) measures an impressive 350 kHz. The lower frequency limit is around 0.3 Hz. No coupling capacitors are used throughout.
Inherently low noise
High resolution audio is intrinsically tied to low noise and distortion. System noise is the lower resolution limit of any analog systems, because it determines the smallest signal not masked by a noise floor. Hence, low noise levels are desirable. A-weighted output noise measures 25μV for the ALLEGRO giving a SNR of 120dB or an equivalent to 20 bit. 20 to 21 bits analog resolution is the realistic limit, restricted by the laws of physics (e.g., thermal white resistor noise)
The power supply consists of a 230VA toroidal mains transformer and a total of 60.000μF energy storage capacitors, enabling a stable output of 55W/90W at 8Ω/4Ω. Precision regulated supply voltages for preamp and driver stages. Microprocessor controlled – non intrusive protection circuits against over current, DC-offset or over temperature.

"In many ways, the work of a critic is easy. We risk very little, yet enjoy a position over those who offer up their work and their selves to our judgment. We thrive on negative criticism, which is fun to write and to read. But the bitter truth we critics must face is that in the grand scheme of things, the average piece of junk is probably more meaningful than our criticism designating it so. But there are times when a critic truly risks something, and that is in the discovery and defense of the new. The world is often unkind to new talent, new creations. The new needs friends. . . . Not everyone can become a great artist, but a great artist can come from anywhere.
Those words, spoken by the mordant food critic Anton Ego, a character in Pixar’s lovely film Ratatouille, crossed my mind as I sat down to listen to Clones Audio’s 25iR integrated amplifier..." review link here
