Audio Alchemy PS-5 Power Station Power Supply Upgrade
Dramatically Enhance the Performance of the Audio Alchemy DDP-1 or PPA-1: With Two Discrete Power Supplies, PS-5 Power Station Upgrades Dynamics and Detail While Lowering the Noise Floor
Dramatically increase the performance of the Audio Alchemy DDP-1 preamplifier/DAC/headphone amplifier and PPA-1 phono preamplifier with the outboard PS-5 Power Station power supply upgrade. A relatively affordable and delightfully simple way to enhance dynamics, improve detail, boost spaciousness, and lower the noise floor of your music, the Peter Madnick-designed PS-5 gives you a much more advanced power supply in the form of two discrete, regulated power supplies. One is devoted to analog circuits, the other for digital and control circuits. Each is routed into DDP-1 via a unique multi-pin connector that optimizes their singular qualities. Internal AC-to-DC conversion prevents any possible interference with the sensitive analog circuits inside DDP-1. A balanced power supply with separate analog and digital feeds, isolated positive and negative rails for analog circuits, and large storage capacitors provides additional filtering refinement. Aesthetically, the U.S.A.-made PS-5 even nests right into DDP-1 so that the two components visually appear as one unit. Audio Alchemy has thought of everything with this combination. Music Direct's Money-Back Guarantee sends it over the top.
"Compared with the stock power supply, the PS-5 vaults the DDP-1 into a different league. The sound with the PS-5 is more refined, spacious, and detailed. Instrumental textures are more liquid and natural. The upgraded supply also gives the sound much greater dimensionality, with a heightened sense of layering and depth, along with more air between instrumental images."

"The Audio Alchemy DDP-1 and PS-5 sonically reproduced a great musical experience in my listening room. Recreating the delicacy of female vocals, the dirt of southern rock guitar, and delivering the emotion of my favorite heartfelt music, the DDP-1 and PS-5 ascended to the top of their respective product categories."

"And the lifelike dynamics of this ‘live take' recording [Vantage Point's Resolution] were impressively visceral, the depiction of the band's verve and energy keeping me on the edge of my seat as the DDP-1/PS-5 combo helped my system recreate a most convincing musical event."
