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!
Seducing warm sound
300W per channel
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.
