Fully complementary circuitry: The Perseus's balanced audio circuitry is essentially two mirror-imaged preamp circuits, one to amplify the positive half of the audio signal, the other to amplify the negative half. The fully balanced design cancels the effects of interference-an important capability considering the low level of the signals inside a phono preamp-and also increases slew rate and frequency response.

Mechanically isolated circuit board: The audio circuit board floats on an elastomeric suspension to isolate it from the effects of outside vibration. Consider it like a raft floating on a calm lake, protected from disturbances on shore.

Machined solid aluminium chassis: A heavy aluminium chassis with 8.2mm minimum wall thickness shields the internal circuitry from all forms of electromagnetic interference, and also helps damp vibration that might affect the audio circuitry.

Balanced and unbalanced inputs and outputs: Easily interfaces with any turntable and any preamplifier.

Three moving-coil inputs, one moving-magnet input: Ample inputs even for the most exotic triple-tonearm turntables.

Adjustable source impedance: The Perseus provides enough adjustment range to suit any cartridge manufacturer's specification or any personal taste. Source impedance for the moving-coil cartridge inputs is continuously adjustable from 3? to 500?, while source impedance for the moving-magnet cartridge input can be set to 33K?, 47K?, 68K? or 100K?

Adjustable load capacitance :The Perseus's load capacitance can be set from 200 to 400 pF in 50-pF increments to meet the needs of any moving-magnet phono cartridge.

Separate power supply: A separate power supply enclosure protects the sensitive analog audio circuits from interference. A high-quality R-core transformer feeds the analog audio circuitry while a separate supply feeds the Perseus's control circuitry. Hypersonics cables and connectors provide a reliable, high-current power transfer. The result is an ample and consistent supply of clean DC.
