Our most advanced preamplifier to date
“This is a rare component in the way it disappears, revealing nothing but the music carried through it. I’ve yet to hear one that reveals more music.”
– Jeff Dorgay, TONEAudio
Sophisticated two chassis design
The audio circuits are isolated within a second box for better signal accuracy.
Suspension for complete microphonic annihilation
giving incredibly lifelike natural sound.

Features
Design features
2-chassis design with 1 chassis housing the power supply, digital controller circuitry, software processing & the LED display. The other chassis contains ONLY audio circuitry.
Power supply voltage regulation includes i 2 DCf (Independent Inductive DC Filtering); 1 inductor for each and every IC in the audio circuit’s signal path – 40 stages in all.
Gain offset adjustment of ±10dB for each line input.
Each line input is fully configurable to be “home theater ready”, whereby the 850P’s volume control is bypassed.
