 audio alchemy was a high end audio equipment manufacturer based in california, usa. it produced many lines of relatively affordable audio products, including cd players, transports, digital audio processors, and amplifiers. they have since gone out of business, the primary engineers moving on to found channel islands audio and (now defunct) perpetual technologies. audio alchemy products made innovative use of the iÂ²s audio interface, usually reserved for the internal connection between the cd transport and dac of a cd player. audio alchemy brought the interface out to a din connector, allowing a very low jitter connection between the cd transport and external dac, by transmitting the clock signal and the audio signal in parallel. this offers a superior alternative connectivity method to something like s/pdif, which sees the clock signal embedded into the audio signal. the process of extracting the clock signal from the data stream is where jitter is introduced. perpetual technologies and camelot technology also produce products that use the iÂ²s interface. several members of the original audio alchemy team, including peter madnick, audio alchemy's co-founder, have formed alchemyÂ². ==acronyms used in audio alchemy products== *dde â digital decoding engine, a digital to analogue converter *dds â digital drive system, a transport *dti â digital transmission interface, a digital to digital processor ==product history== ===cd transports=== *dds 1.0 (sony drive based three blocks transport) *dds 2.0 (aka dds ii sony drive based transport) *dds 3.0 (aka dds iii sony drive based transport) *dds pro (pioneer stable platter drive based two blocks transport) ===cd players=== *acd-1 *acd-2 *acd pro (pioneer stable platter drive based player) ===digital processors=== *dde 1.0 â 1-bit *dde 1.1 *dde 1.2 â 20-bit, hdcd, toslink/bnc/xlr/i2s inputs (similar to dde 3.0) *dde 2.0 â 20-bit, toslink/3xbnc inputs *dde 3.0 â 20-bit, hdcd, toslink/bnc/i2s inputs (optional dithering and remote control processor) *dti 1.0 â a jitter reducing processor *dti 2.0 â a jitter reducing processor *dti pro â a jitter reducing processor *dti pro32 â a jitter reducing and dithering processor *dti+ â a jitter reducing processor *ultradac â combination of a dti and dac-in-the-box (ditb) in one chassis *dac-in-the-box â an inexpensive dac *dac*man â an inexpensive dac with integrated analog audio cables *edi â extended digital interface, an bnc in â i2s out jitter reducing processor *xdp â extended digital processor, an i2s input dac ===preamplifiers=== *dlc â digital line controller, a remote-controlled preamplifier *lis â line input selector, tape loop and input/output expander for the dlc *vac-in-the-box â a dedicated mm/mc phono preamplifier ===amplifiers=== *o
