The Oracle Transcription Turntable burst onto the high-end scene in 1979 and has been an icon and technical tour de force ever since.  

It is Oracle's belief that achieving simplicity in design is a combination of knowledge and common sense.  A properly designed device creates its own form, one that reflects the beauty of it's function.  True artistry combines these elements by means of the whole being greater than the sum of its parts.

This philosophy has produced turntables and CD players which are both Stereophile Class A recommended components - they look and sound superb.

The Delphi Mk VI Turntable

This new reference turntable really delivers exquisite sound at a very reasonable price.  The basic engineering is so good that the performance is predictably excellent.  The additional suspension damping further enhances resolution by controlling micro-vibrations.

The Delphi works particularly well with the new Oracle 345 arm, manufactured for Oracle by SME.  It also works extremely well with the Graham tonearms

The Delphi is available in different finishes.

The Oracle Temple Phono Stage

Release to celebrate the 25th anniversary of Oracle, the Temple is a very high quality, extremely flexible phono stage designed to compliment any high-end turntable system.

The Oracle CD 2000 Drive and CD 2500 Player

Available both as a CD Player or as a Transport, this remarkable unit is a true successor to the marvellous Oracle analogue turntables.

The CD Drive is a stand alone CD Transport for use with an external D/A converter, and offers two electrical outputs and one optical output.

The electrical outputs are :

- SP/DIF (75 Ohms) via a high quality BNC chassis socket, and
- AES/EBU (110 Ohms) output via a XLR chassis socket of the finest quality.

The optical output is :

- Hewlett-Packard - HFBR 1412, AT&T (glass) type.

The turntable mechanism is the Philips CDM 12.4 Pro, selected because of its ease of upgrade to next generation technology, and of course its sonic capabilities.

The CD Drive should be partnered with only the finest D/A converters, and will stand head and shoulders above the competition anyway, and particularly when used with converters capable of up-sampling.

The CD Player, similar in specification to the transport described above, has its own internal D/A converter, and is using the I2S signal from the CDM 12.4 Pro.  The internal D/A converter is based on the Cirrus Logic Crystal one bit chipset and is 24 bit.

The CD Player offers one electrical output only.  This is a SP/DIF (75 Ohms) via a high quality BNC chassis socket.  The analogue output from the internal D/A converter to the preamplifier is via Cardas Rhodium plated RCA sockets.  The remainder of the specification is as for the CD Drive.

THE NEW ORACLE 1000 SERIES

The Oracle DAC 1000 Preamplifier and D/A Converter

The exceptional technology combination between the pre-amplifier and D/A converter sends the appropriate signals to the rest of your audio system leading you to experience enlightening musical emotions.  Oracle's Audio reputation and prestige still demonstrates its ability to defend the leading edge position with the new Oracle DAC 1000.

The Oracle CD 1000 Drive and CD 1500 Player

Basically, the electronic parts are very similar to our famous CD 2000. We created a brand new design, use a brand new exceptional suspension system. The result is a totally perfect CD player....

ORACLE CD - PLAYER ( with integrated d/a converter )

The analogue stage plays a vital role in high performance of the Oracle CD player , it filters the quantification residues , it eliminates left over pollution from the supplies in a common mode and the electrical rejections of the different internal circuitry of the CD engine drive board.  The fine tuning of our digital to analogue converter board has resulted from a 3 years intensive research program before reaching our goal. The goal was to eliminate the need for, and use of internal pre-amplification circuitry needless to say we succeeded.

ORACLE CD - TRANSPORT

The Power Supply Stage

Our special power supply section is designed in such a way that each major element will have its own dedicated primary and secondary electrical supply.  Each transformer is encapsulated in a special epoxy to further reduce vibration.  There is a dedicated transformer for the drive engine and command functions and a second dedicated to the digital to analogue converter. The line signal is filtered prior to arriving at an EI transformer that is immune to electrical pollution. Both primary and secondary supplies are magnetically shielded by a galvanized screen thereby eliminating any pollution in this domain. The main power supply housing also provides efficient shielding against radiated pollutants. The secondary supplies to the toroidal transformer used by the digital to analogue converter are individually rectified through soft recovery rectifier circuit and capacitors in a PI network thus increasing filtering efficiency. This means all electrical signals going to the player are completely free from external pollution.

The Command Module

Only DC signals enter the command module where all necessary voltage regulations are located.  This command centre controls and directs the signal to each critical element. Also located here are the fluorescent display, infra-red receiver for the remote control and the mechanically operated function selector switches. This separate command module also provides further very effective shielding due to its complete isolation from other keys elements.
