Design Features

A classic architecture had been chosen to provide a firm foundation for the RIAA equalization and gain stages of the Phono1.

The RIAA uses a robust series EQ architecture with high precision, low noise, high linearity resistors and high precision polypropylene film and foil construction capacitors for optimum signal transfer. The Moving Magnet gain is in the RIAA Equalization stage, using the latest ultra low distortion, low noise monolithic preamplifier device. This device combines extremely low distortion with low offset, noise and high output drive capability to be a transparent conduit for the musical signal. The high performance gain and equalization setting RC elements dominate the musical signature of this MM/EQ stage, leading to a detailed yet musical presentation. The MM/EQ stage provides 40 dB of 1kHz gain.

The MC gain stage is connected optionally before the MM/EQ stage and provides extremely low noise and low distortion, again using high performance resistors for gain setting and adjustable input loading. The MC stage is connected into the circuit using gas tight gold jumpers, these jumpers also are used to set the MC stage gain at 14 or 20 dB. This provides up to 60 dB of 1 kHz gain for use with low output MC cartridges.

No coupling capacitors are used in the signal path, removing this source of signal degradation. A servo is used around the MM/EQ stage to insure low DC offset for direct coupling to the control preamplifier.

There is over 10,000 uf of capacitance and LC high frequency filters providing the raw DC.

The first stage of filtering drives eight (4) individual regulators providing power

to the analog circuits, where audio grade electrolytic and film bypass capacitors complement the active regulation stages. A highly isolated power transformer, oversized by 10X provides extremely low-noise and robust raw power to feed the precision regulators.

The input impedance, gain and relative noise levels can be optimized for virtually any cartridge available. This is achieved through the use of gas tight gold jumpers and precision miniature switches to simplify the optimization for virtually any cartridge.

The elegant simplicity of the signal path allows the Phono1 to preserve the entire audio signal.

Warm Up

The Phono1's sonic performance will start to stabilize after approximately forty (40) hours of continuous power up.
