One owner, very good cosmetic condition. Works as it should. Original power supply included and new rubber feet. Heres a review from stereophile https://www.stereophile.com/content/audio-alchemy-digital-decoding-engine-v10

Up for grabs is a Power Station Two and a Digital Decoding Engine v1.0. “DDE v1.0. The DDE works perfectly sans the I2s connection. Unsure if the i2s works or not as it is an oddball I2s with a 4 pin connector instead of the Audio Alchemy standard 5 pin I2s connection. As a result, no means with which to test the i2s. Included will be a cable to power the DDE from the PS2 and a power cord for the power station. The feet on the DDE are super sticky. I recommend post it notes on said feet to prevent marring of any surfaces. The cosmetics are average for both units given their vintage. Both units function well as described. Inputs are optical toslink and coax. The power station 2 can power a total of 3 Audio Alchemy units. Very nice indeed.

A chance to own a classic from AUDIO ALCHEMY and is the DIGITAL DECODING ENGINE- DDE v1.1. Used and tested and in excellent condition. Unit is a HIGH END, full function, outboard digital processor. Complete with coaxial and optical inputs provided via RCA and TOSLINK JACKS. It also has an absolute polarity switch and 3 LEDs that indicate when the unit is locked to an incoming signal. Included with the unit is the optional, AUDIO ALCHEMY POWER STATION ONE, HIGH CURRENT POWER SUPPLY! This was in my late brothers system and it sounds great! The optional (HIGH END) power supply makes a (world of difference) all around! Specs: frequency response, 20Hz - 20kHz +1-0.2dB, S/N < -86dB. No box or manual!--TAKING OFFERS!
