About the Spheris Phono

The Ayon Audio Spheris Phono is a state-of-the-art vacuum tube phonostage preamplifier designed to deliver natural musical performance with an extraordinarily wide bandwidth, extremely low distortion, and superior dynamic range. It operates in pure Class A triode mode and uses a tube complement of 6H30 and 6SL7 tubes. The unit features high-quality audiophile-grade components including beryllium-copper spring pin tube sockets, WBT RCA input jacks, Neutrik XLR connectors, and premium internal wiring with ultra-pure copper. The chassis is made of high-grade aluminum with anti-vibration and resonance-absorbing properties, finished in black or chrome. It includes an AC Regenerator power supply for stable, purified AC power, enhancing sound clarity and imaging. The Spheris Phono offers a maximum output of 5V rms at 1 kHz, a signal-to-noise ratio greater than 100 dB, and a frequency response from 10 Hz to 80 kHz. It has inputs for 2 phono RCA and 2 load settings, and outputs via 1 RCA and 1 balanced XLR. Dimensions are 50x43x11 cm for both preamp and power supply, with a combined weight of 46 kg.
