For sale is a set of Audio Alchemy digital equipment: Digital Transmission Interface (DTI) Pro32 (in box)Digital Decoding Engine (DDE) v3.0Power Station ThreePower Station Four (in box) The DDE 3.0 and DTI Pro32 both power up OK. Since the DIN power cord is missing for the Power Station Three, I only used Power Station Four to test DDE and DTI. I flagged For Parts/Repair because I only did limited testing as follows. I fed digital signal to the optical input on DDE, and the front LED showed locked OK. However, I didnt get music to the audio system downstream. I suspect I need a remote to unmute or something. Anyway, I was not able to get music out from the analog output. For DTI Pro32, I only powered it up and front LEDs lit up. I didnt have proper cables to hook it to DDE but its pointless to do that because I cant get music anyway. The Power Station Four appears to be used for 100V but I didnt detect any issues when I plugged in 120V socket. The physical condition is good, with typical wear and scratches. Nothing is nasty. The original box is for DTI and Power Station Four. No cable, manual, or any other accessories. I pack very well and ship worldwide. I welcome local cash transaction.

Hoping this helps someone who needs it

For sale is my DDE V 2.0. This is a very smooth sounding DAC. Unit performs flawlessly and is in very good cosmetic condition. Includes a power cord.

Soundausgabe verzerrt bzw. nicht vorhanden. Samplefrequenzen werden teilweise nicht erkannt. Gute Optik! Verkauf ausdrücklich als defekt, keine Rücknahme! Sound Output distorted resp. no output. Sample fequencies are not identified. Good optical condition. Explicitely sold as defect, no returns accepted! Noch ein kleiner Kommentar zu den von mir als defekt angebotenen Geräten: Die Geräte werden von mir lediglich kurz getestet. Aufgrund dieses Tests erfolgt die Beschreibung. Die Geräte werden NICHT von einem Techniker durchgeprüft noch wird der Reparaturaufwand bewertet. Weitere Defekte kann ich aufgrund des Kurztests nicht ausschließen. Sie müssen SELBST entscheiden ob Sie das Risiko eines Kaufes eingehen und ob Sie sich eine Reparatur zutrauen. Das Gerät zu einem Profi zu geben wird sich sicher nicht rechnen. Wenn Sie selbst Profi sind umso besser :-)

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.
