Power Amplifier

The Evolution of amplification… Massive power reserves allow the music to reproduce effortlessly at any volume level.


No global feedback for fast and lifelike musicality
"There was also outstanding image focus from left to right and from front to back, making performers’ positions onstage easy to discern […] The 870A’s re-creation of the spaces around musicians was a product of its topnotch reproduction of resolution and detail." 
– Doug Schneider, SoundStage!



  • Design features
    • Our “Lynx” Technology which eliminates feedback and results in: real-time amplification; more accurate musical reproduction with respect to tonality; non-existent transient intermodulation distortion; the elimination of phase errors resulting from feedback.
    • Output stable to any known speaker impedance.
    • A high damping factor for superior musical dynamics, improved signal speed and refined timbre accuracy.
    • Self-diagnostic system that detects both over-heating and the presence of DC in the input signal.
