Enhance your digital audio experience with the AUDIO ALCHEMY DTI Digital Transmission Interface and XDP. This top-of-the-line device boasts 3 inputs and 2 outputs, making it perfect for any home audio setup. The sleek black design adds a touch of style to your entertainment center, while its powerful digital features ensure clear and crisp sound quality. The model is a must-have for any serious music lover looking to take their listening experience to the next level. Better than from factory with the pairing of DTI and XDP devices. Power supplies for each unit. explanation for DTI found online: Digital playback has come nearly full circle since the first CD players were introduced over a decade ago. Early CD players were just that - single-box entities containing both a transport mechanism, for reading the digital data from a compact disc, and a digital-to-analogue converter (DAC) for converting the retrieved digital data to an analogue signal. Unfortunately, early CD players were not readily upgradeable, mandating either their complete replacement or significant internal modification if sonic improvements were to be realized. The eventual introduction of the external digital interface and outboard DAC solved the upgrade problem, but ushered in yet another - jitter, or timing errors, introduced into the digital data stream due to the need to now recover the CDs embedded digital clock via the digital interface. Audio designers, fueled by consumer demand for sonically-excellent two-box digital systems, were determined to find a solution to the jitter conundrum. Their research and development efforts led to products like the Genesis Digital Lens, the Sonic Frontiers Ultra Jitterbug, and the Audio Alchemy Digital Transmission Interface... On the XDP, found online: To me the DTI, XDP in combination with PS ONE and PS Four (2 voltage PSU for XDP) are the very best of Alchemy. The 1.0 + DTI is a kind of charming, but resolution is somewhat lower than DTI, XDP. The later models became just duller and duller, ending with DTIpro and DDE 3.0, which I happen to dislike. The upgrade PSU called Powerstation TWO is a regulated 2 voltage PSU providing 12 and 18 V I think, but this is not really an upgrade, since both XDP and DTI runs a lot better on the PS FOUR and PS ONE, probably because of the higher voltages. Btw the regulators are just simple 7812/7912 and 7818/7918 types, so don´t waiste your money and attention on that. Compared to more modern DACs the DTI, XDP still is of interest to audiophiles...

Audio Alchemy Digital Decoding Engine V3.0 + XDP Power Station + RW-1 RemoteMultibit sound quality - AD1862N DAC chips From my personal equipment collection. This DAC has been in my headphone rig for several months getting regular use. The XDP Power Station has the same specifications as the Power Station 4 and works fine. The DDE V3.0 has the optional specially programmed Intel 87C51 micro-controller installed. This allows remote volume control, input selection, channel balance and muting of the DAC via the RW-1 remote. The remote is not necessary to use the DAC.I am selling due to downsizing my audio equipment collection. I have another DDE 3.0 that I am now using that works fine, but does not have the optional Intel chip like the one that is listed for sale here. That is why the remote is being sold in this listing. A printed copy of the operating instructions for the DDE 3.0 and RW-1 will be included. As information, I prefer the DDE 3.0 with the XDP or PS4 power supplies versus the PS2 or PS3 units, as I find the PS2 and PS3 units to be mechanically noisy due to transformer hum.I have tested all 3 digital inputs (optical, coaxial, and I2S) and all work fine. The I2S input must be connected to a DTI device that has an I2S output. I have a DTI unit (not for sale) that the I2S connection has been tested with. I also have played HDCD discs through the DAC and the HDCD light comes on. I am including a BNC to RCA adapter to allow using a standard RCA digital coax cable. I have the internal gain control set at position 1 for an output of 1.14 V RMS. There are 3 other settings that can be used by changing the shorting plugs to different jumper positions. The RW-1 remote works fine in all listed functions, as noted above. There is a small micro switch on the side of the remote that allows it to function with the DDE V3.0. Set the slide switch (on the right side of the RW-1) to position 3; all the way back, towards the battery end of the remote. The RW-1 also will control the DLC preamp, which I used to own. Will be double boxed for shipping. If you have not owned Audio Alchemy gear before, I will point out that the instructions recommend doing all cable connections to the DAC before connecting the power cable. I have followed this method with all the various Audio Alchemy gear I have owned with no issues. This DAC was one of Stereophiles Joint Budget Components of 1996.
