To avoid pcb copper interaction we opted for a point - to - point build, using star ground topologies.

After several years investigation in the Class A amplification using jfet implementations we developed a High Definition Phono Pre-Amplifier that benefits from low noise and low distortion possible with those components. Basically an amplifier modulates the output of the power supply with the incoming signal so the PSU must be clean and fast, especially with ultra-low-level signals from MC cartrid

ges. We needed a very silent power supply without the issues related with batteries so we searched for the latest shunt technologies that provide very low noise power with very low output impedance, increasing detail and attack. To provide maximum headroom the shunts are powered by a large R-Core transformer followed by low noise ultra fast rectifiers and special 4 pole EL smoothing capacitors. All power and ground wiring are made with teflon covered silver cable and the signal is conducted on HQ shielded high purity copper cable. Principal characteristics:

- Hand built - Double mono implementation.

- Class A amplification without Negative Feed Back.

- Passive Riaa equalization built with high performance parts.

- Two stage discrete amplification.

- Internally shielded R-Core, 120VA Transformer.

- 15.000uF 4 pole EL filtering capacitors for each channel.

- High Current Shunt regulators.
