Audio Alchemy DDP-1 DAC/Preamplifier w/ PS-5 Power Supply

For sale is an Audio Alchemy DDP-1 DAC/Preamp with optional PS-5 power supply in very good condition.  This is the original model made in the USA unlike the newer version.  There is a minor hairline scratch on the top plate of the preamplifier and some smudges of the matte black tops of both units as can be seen in the photos.  There is a small abrasion just under 1/2" long on the top edge of the faceplate of the preamplifier above the left knob.  I had not noticed it during my first visual inspection, but it showed up in one of the photos, and is visible if up close under the right lighting.   Firmware has been updated to the latest version and includes the original packaging and remote.   Reviews from Robert Harley of The Absolute Sound and Alan Sircom of Hi-Fi+ attest to the extraordinary sound quality and value of these pieces: https://www.theabsolutesound.com/articles/audio-alchemy-ddp-1-preamplifierdacheadphone-amplifier-dpa-1-stereo-power-amplifier-and-dpa-1m-monoblock-power-amplifiers/ https://www.hifiplus.com/articles/audio-alchemy-ddp-1-dacpreamp-ps-5-power-supply-and-dpa-1-power-amplifier/
