AudioValve's Conductor (9800€) is a fully symmetrical vacuum tube reference preamplifier and is the second product rolled out by AudioValve within the past year.
With two decades of experience, this new preamplifier features a whole range of innovations and features of the valve and processor age. As such, it combines the elements of signal processing in a completely new fully symmetrical circuitry design. The amplifier is separated in three components: signal component, power supply and micro-controller. Signal and power supply components come in separate casings while the controller is part of the amplifier display and handles all tasks in terms of control. Left and right channels are strictly designed as dual mono, within the power supply as well as the signal component. The power supply features for the anode potential alone nearly 10,000µF/400VDC and for the heater component 100,000µF see to the necessary DC voltage on a 30x30cm circuit board. An oversized toroidal transformer with static and magnetic shielding supplies a total of 8 conductor paths, four for the production of the anode potential and four for the heat production. The volume is controlled behind the first amplifier stage, thus the first stage can fully develop its 'tubal' tonal dynamic freedom and supply the output drivers.
Overall, there is no feedback loop, input impedance is 47kOhm and output impedance 300 Ohm. Frequency response is from 5Hz to 200kHz. There is a total of six stereo XLR and six stereo RCA inputs, while outputs include two stereo sets of both XLR and RCA. Valves in the Conductor include four 6H30 (6N6P) and four 6922.
