Ayon Audio Spheris II Phonostage

AYON AUDIO Spheris II Dual Chassis Phono Stage

“State of the art”
Ayon Audio Spheris II – Phonostage is designed to be the new reference standard in vacuum-tube phonostage pre-amplification and for audiophiles who will accept nothing less than simply the best. It is a marvel of engineering with its unique tube circuit design and construction. This preamplifier sets a new standard for natural musical performance with its extraordinarily wide bandwidth, extremely low distortion, colourful, superior dynamic range and an airy three-dimensional holographic soundstage.

The external Spheris II AC~ Regenerator offers stable, regulated and purified AC power regardless of the incoming AC line quality. This power supply provides a lowered noise floor, more liquidity, better spatial three-dimensional imaging, greater focus, richer colours, and decreased glare & haze.
