What reviewers think

Bloggers and YouTubers have tried this product—so we've summarized their strongest opinions below. Links to full reviews follow.

What are hifi reviews useful for? (1) Identifying products you should demo in person at a dealer. (2) Learning which products reviewers unanimously praise as the best they've heard (this means they probably are legitimately great). (3) Identifying a product's attributes that satisfy your idiosyncratic needs and tastes. Beyond that, we often discount what reviewers say because they heap praise on most products—and are often apprehensive about publishing strong criticism or comparisons between products. Further, they seldom have more than a few products on-hand, often relying on their memories to compare past products. Always listen for yourself.

For our Cessaro Air two we decided to use a single-ended tube amplifier with only two amplifier stages and two output tubes in parallel circuitry. The extreme labourious winding method of the output transformer creates a perfect behaviour even with parallel operating output tubes.
For our Cessaro Air two we decided to use a single-ended tube amplifier with only two amplifier stages and two output tubes in parallel circuitry. The extreme labourious winding method of the output transformer creates a perfect behaviour even with parallel operating output tubes. Due to the usage of very few parts and directly coupled with only one „plate choke" between the first and the second amplifier stage, there are no interstage transformers or capacitors in the signal path. This concept results in a super-fast reaction of the pulse processing, combined with a natural sound pattern of highest resolution and emotionality.

The Cessaro Air two uses a simple circuitry, a huge dimensioned output-transformer (custom made core size) specially made of finest core material with silver winding on primary and secondary side, a very low output-impedance, an extreme expensive power supply for the high voltage range and the filament voltage with separate power supplies for each tube section combined with the finest NOS-Tubes. The audiophile listener will experience something special in sound – guaranteed. The perfect match for any real horn system.

Audio tube-amp manufacturer all around the world know very well, that it is a challenge to get a tube amp dead quiet (hum- and hiss-free) without using a volume pot in the signal path combined with a very high efficient Horn-Loudspeaker...

Brand highlights

Taking a step back to look at reviewers' thoughts of the brand's entire lineup—not just this product—what stands out most is the following:

C1  

  • Positioning: An integrated active system designed for plug‐and‐play simplicity and seamless connectivity.  
  • Description: Features a built-in DSP crossover, a separate DAC preamp, and dedicated power amplifiers in a complete floorstanding unit with a classic piano lacquer finish. Compared to traditional passive systems like the Liszt II and other high‐end models, the C1 offers a streamlined setup ideal for smaller rooms and a lower budget while still delivering high-quality sound.

Liszt II  

  • Positioning: A 4-way horn system focused on delivering dynamic realism with all built-in components.  
  • Description: Integrates frontloaded bass horns driven by large papercone and alnico drivers along with a novel spherical composite midrange horn, ensuring clear and lively reproduction. Compared to the integrated C1, follows a traditional passive design that is lighter and more suited for moderately sized rooms than the heavier, more complex 5-way systems.

Gamma II  

  • Positioning: A versatile 5-way horn setup that offers flexible bass horn configurations for refined live-sound reproduction.  
  • Description: Provides multiple bass horn options—including configurations with up to eight power amplifiers—combined with spherical composite horns and advanced TAD drivers for agile low-frequency performance. Compared to the Beethoven II, its configurable design and slightly more compact build offer buyers a customizable performance alternative without the extreme scale of the ultimate system.

Beethoven II  

  • Positioning: A high-end 5-way loudspeaker system engineered to emulate the acoustics of live concert halls.  
  • Description: Uses built-in frontloaded horns for every frequency band, featuring TAD compression drivers with beryllium diaphragms and bespoke composite horns to closely mirror live performance. Compared to the Gamma II, the Beethoven II is larger and heavier.

Omega I  

  • Positioning: An ultimate reference loudspeaker system designed for vast, dedicated listening spaces.  
  • Description: Achieves 112dB/1W/1m efficiency using an array of massive 16" bass units driving frontloaded horns, delivering exceptional dynamic range and power. Relative to all other models, the Omega I demands an auditorium-like environment.
