Usher P-307A MK2

P-307 is the control center of today's high-end audio system. The two main functions are signal source selection and volume control. We make every effort to keep the P-307 as accurate as possible. In order to avoid unnecessary interference with adjacent original components, P-307 uses high-quality relay and switch design to ensure that each signal source is intact. Therefore, all signal sources are still separated from each other, and from the power amplifier and cables.

In today's digital age, analog preamplifiers are still the most reliable components for volume control and the most neutral sound quality. P-307 uses an excellent attenuator to provide neutral sound performance.

Due to the noise generated by the AC power supply, the power supply of the P-307 adopts a separate power supply box, so the audio circuit of the P-307 is more suitable for a quiet and stable DC power supply and the audio signal itself.

Arthur P-307 is a modern reference level preamplifier. After all, only when the P-307 shows a touchable imaging focus and sound field, a sense of ease and smooth rhythm, and the subtleties of music details, can music become a real enjoyment.

For music lovers, the Arthur P-307 stereo preamplifier is a rare and affordable high-end product in the city.
