Axiom III Preamplifier

$7,999.00

The Axiom III’s linestage design is an evolution of the Arion MkII output
stage circuitry and is cut from the same sonic cloth as the Arion MkII
Phonostage. Utilizing a cascoded J-FET differential input stage and bipolar
Class-A output stage. The Axiom III will drive any cable or load with ease.

The high resolution JFET input stage was developed to interface to extremely
low signals of a MC cartridge and provide the same level of signal integrity to
wide dynamic range line level musical signals.

The AXIOM III Linestage’s volume is controlled by a relay-based ladder
configuration control that is controlled by a microprocessor-based control
circuit. The advantage being that the signal path has only one high quality
resistor in the signal path at any volume setting. Volume settings are
accomplished through high quality Telecon style low-signal application
devices, eliminating the sliding wipers and resistive films used in rotary
volume controls. Once again preserving as much of the music’s subtleties,
which is where the magic in any recording is encoded.

Like the Arion, the power supply utilizes a high-current toroidal power
transformer, using the same configuration of isolating the positive supply
from the negative with a common carefully routed ground net. There are 4
+/- DC supplies (dual mono configuration), +/_ pairs per channel.

Operation is remote control operated with a display reporting current setting.
