Lineup comparison

We think it's helpful to understand how their products compare. To learn more about each, scroll to the section above to click through to individual product pages.

Aurora One Tube Line Preamp & Buffer  

  • Positioning: A flexible tube line preamplifier and buffer designed for versatile integration into modern audio systems.  
  • Description: Offers advanced on-board gain matching with low noise operation, enabling independent buffering and pre-programmed gain modes for consistent volume matching across varied sources. Compared to the phono preamplifier and power amplifiers in the lineup, it delivers practical functionality for users needing high-quality line-level signal conditioning at a more accessible price point.

Kaskode One Phono Preamp  

  • Positioning: A Class-A phono preamplifier specifically engineered to extract optimal performance from turntable cartridges.  
  • Description: Features a fully tube-based, open-loop design using NOS Siemens D3A and EC8010 tubes for extremely low noise and precise RIAA equalization with configurable gain for both MM and MC modes.

288 Power Amplifier Monoblock Pair  

  • Positioning: A robust 60-watt tube power amplifier based on an ultralinear push-pull design aimed at delivering dynamic performance.  
  • Description: Uses KT88 tubes and a custom 13.5-pound ultralinear output transformer to achieve wide bandwidth and low distortion while maintaining precise control over low frequencies. Compared to the lower-powered SET designs and higher-priced flagship models, it offers an attractive balance for users needing more power with broad sonic capabilities.

22A3 Power Amplifier Monoblock Pair  

  • Positioning: A 5-watt SET tube power amplifier that emphasizes low noise and classic triode sound for high-efficiency speakers.  
  • Description: Uses a total parallel design using 2A3 tubes and a custom output transformer to deliver refined low-level dynamics and exceptional midrange clarity with minimal distortion. Compared to the 288's higher power push-pull approach and the premium 2845 model, it targets users who prioritize the intimate SET sound and detailed tube matching.

2845 Power Amplifier Monoblock Pair  

  • Positioning: A groundbreaking 50-watt SET tube power amplifier that pushes open-loop design to deliver uncompromised audio performance.  
  • Description: Features a parallel single-ended triode configuration with an in-house developed output transformer and massive, low-ripple power supply to drive both high and low efficiency speakers with exceptional low frequency authority and clarity. Compared to the lower-powered 22A3 and Class-AB 288, it represents the pinnacle of advanced circuit design and superior performance.
