TAD Reference Preamplifier
The C700 is TAD's flagship preamplifier, designed around the idea that the shortest, most symmetrical possible signal path gives the most accurate reproduction.
A single-stage current-feedback flat amplifier keeps the active signal path minimal, while fully balanced, dual-mono construction and a physically separate outboard power supply (with a 400VA toroidal transformer) keep noise and vibration away from the audio circuit. A custom ladder-resistance electronic volume control delivers under 0.1dB of error even at deep attenuation, and Extreme Link lets a master C700 control multiple slave units for multichannel systems.
