1. Introduction
Thank you for your purchase of Carot One AUGUSTOLO TUBE MM / MC
phono pre-amplifier.
We are not satisfied with the sound of today's LP playback systems; most of
them sound too neat and clean, even tasteless, like distilled water. With
AUGUSTOLO TUBE, our intention is to enhance the richness of LP sound,
and differentiate it even more from the sound of a CD. The sound that
AUGUSTOLO TUBE created was the target when we were developing
progression. With an addition EH6922 vacuum tube to this new model, it
bring you all the benefits of vacuum tube playback even playing on any
transistor amplifier.
2. Features

release of vibrations.
Improved RIAA accuracy and even lower noise floor.
Ultra-low noise and low distortion RIAA
Standard audio sockets compatible with most audiophile quality cables.
Audiophile-graded parts and components
Adds a clean retro sound to any Hi-Fi system.
The stylish & specially-plated aluminum case provides not only
good-looking, and also provides outstanding shielding capability.
