ALCHEMY PS-5

PS-5 Power Supply Upgrade

DDP-1 owners, the PS-5 is an easy and affordable way to improve dynamics, lower the noise floor, and enhance detail, spaciousness and musicality. It immediately and substantially elevates the performance of the DDP-1 by adding a much more advanced and capable power supply. It also complements the aesthetics of the DDP-1, by nesting into the unit, so the PS-5 looks like an integral part of the system rather than an add-on accessory.

Sound power

Inside the PS-5 are two separate, regulated power supplies: one for analog circuits, the other for digital and control circuits, which provide each the unique power qualities required to maximize their performance. These discrete supplies are routed into the DDP-1 (DAC/Preamp/Headphone Amp) through a special multi-pin connector on the rear of the unit for easy connectivity. Additionally, the AC-to-DC conversion is performed inside the PS-5 to prevent interference with the sensitive analog audio circuits inside the DDP-1. A balanced supply with separate analog and digital/control feeds, separate positive and negative rails for analog circuits, and large banks of storage capacitors for better filtering and improved dynamics.
