Overview
The Spheris III – Linestage is designed to be the new reference standard in vacuum-tube linestage pre-amplification and for audiophiles who will accept nothing less than simply the best. It is a marvel of engineering with its unique C3m tube circuit design, a new revolutionary volume control system and construction. This preamplifier sets a new standard for natural musical performance with its extraordinarily wide bandwidth, extremely low distortion, colorful, superior dynamic range and an airy three-dimensional holographic soundstage. The external Spheris III 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 colors, and decreased glare & haze.
