The Delphi subchassis / platter / tonearm assembly is suspended by a tripedal mounting, which eliminates room vibrations. Each suspension tower assembly combines 12 different components, using 7 different mechanical filters, all working as a whole to efficiently control unwanted vibrations.

Bearing assembly:
The traditional two bearing system has been replaced by a new system using six precision surfaced nylon screws. With this, Oracle reaches the highest level of rotational accuracy.

Motor drive electronics and drive belt:
Oracle selected a specially designed AC synchronous motor. The Delphi MK VI features a dual current drive circuitry. This provides maximum start-up torque energy and minimum efficient operational energy, which guarantees lowest possible motor vibration. The molded belt plays an important role in maintaining maximum speed stability.

Record / Platter:
The maximum rigidity of the 4kg (8.8 pound) platter is immune to vibration by distributing most of the mass around it's outer edge. The flywheel effect increases momentum.  Record coupling system (standard): Oracle pioneered the now well established "record clamp system" to solve specific vinyl disc "warp" problems.

Hard acrylic mat:
The Oracle acrylic mat made from specially formulated polymer shows better matching characteristics (impedance) with the vinyl disc.

Oracle demonstrates that superior engineering can also be aesthetic. The hand brushed aluminum with a clear laquer coated skeletal subchassis will dissipate unwanted energy through efficient coupling and clamping methods. Maximum rigidity, minimal surface area and energy control are key design.

The standard plinth is Clear Acrylic. An optional Black Granite plinth is available for an extra charge.

Power Supply:
The Delphi MK VI comes standard with a regular power supply. The optional MK VI Turbo Power Supply is the result of an extensive development and performance comparisons between reference elements such as special batteries and monstrous power source. The Oracle Turbo Power supply outperformed them all! The turbo power source transforms an outstanding performance into a wonderful musical experience. Both power supplies ship with a removable power cord.

Oracle/SME Tonearm (Optional):
The Oracle/SME tonearm provides superbly detailed and transparent sound, making the music seem more alive and open. This tonearm offers differing pivot to stylus distances and was designed for the needs of a broader market requiring alternative arm length and interchangeable shell facility. The internal wiring of the tone arm is upgraded to Van den Hul MCS150 silver litz.

Oracle Paris

Oracle Paris pladespiller

The Paris turntable ... from top to bottom.

The only thing from the Paris that is similar to what we have done in the past is its design signature, everything else is a total redesign resulting from our studies that lead to the development of the best turntable in the world ... the Oracle Delphi Mk VI.

The coupling disc is machined in two separate pieces of Delrin which is a crystalline plastic that offers an excellent balance of properties that bridge the gap between metals and plastics. The dish is independent of the tightening knob to prevent any damage to the record labels. The Delrin is a very efficient mechanical filter preventing the transfer of noise generated by the rotation of the spindle of the platter in its support. Although very minimal because of the built quality of the spindle holder system of the Paris, this rotational noise is always there ... and we are tracking it and minimizing it very seriously!

The platter is also machined in two parts. The under platter made of aluminum is the hub where the drive belt will make the platter rotate with extreme accuracy. The upper platter is made of acrylic, this material is very inert, it does not allow any amplification of resonances, due to the stylus/record groove interaction, which could negatively and adversely influence the quality and the accuracy of the signal retrieved by the stylus which is stored in the record groove.

Acrylic is also a very efficient mechanical filter. The spindle holder which supports the platter spindle uses two high precision bushings made of PEEK which is a high temperature resistant engineered thermoplastic with excellent chemical and fatigue resistance plus thermal stability. The tip of the spindle rests on a thrust plate which is made of the same high performance plastic material we make the bushings with. This is the same material used for the Delphi MK VI. This high performance assembly provides a smooth spindle rotation resulting in an improved signal to noise ration. The impact on the music reproduction is outstanding. You will hear more and cleaner inner details. The platter spindle is a high precision piece, made of stainless steel. The platter and tone arm are mounted on a semi floating chassis. The main frame and the semi floating chassis of the Paris are made of high density wood fiber. This material is very inert because of the nature of its variable inner density which makes it a very efficient mechanical filter.

For improved performance and rigidity the main frame and semi floating chassis are laminated in 3 layers The Oracle mechanical design concepts are always intimately linked to the overlapping of different materials interacting within a same assembly. The Paris is no different! Compared with the Delphi MK VI which has a full floating system with a very sophisticated spring suspension system and micro vibrations stabiliser system, the Paris suspension system is very efficient while being much simpler. It has been completely redesigned taking into account the findings that led to the development of the MK VI. The heart of the MK VI is its ability to control micro vibrations. The Paris uses fibreglass rods and Sorbothane to achieve this complex task.

The combination of these materials contributes to virtually eliminate the access of unwanted vibrations to the semi floating chassis where the platter, the tone arm and the phono cartridge are interacting. This is extremely important to optimize the environment thus allowing the stylus to retrieve the best possible information from the record groove. The Paris is a belt driven turntable. The motor which is a low voltage AC synchronous, the drive belt and the drive electronics of Paris are the same used for the Delphi MK VI.

The drive electronics of the Paris has a very high precision oscillator circuit which creates a perfect sine wave signal to feed the motor thus ensuring high rotational accuracy for optimal speed stability. This system also isolates the drive electronics from line voltages impurities and fluctuations. The power adaptor of the Paris is 24volts DC. Again adhering to the mechanical filtering concept, the adjustable feet are made of Delrin. The convex shapes of the 3 feet procure a minimal contact surface with its supporting shelf. This also contributes to minimize the access of unwanted energy through the turntable system. The Paris turntable can accept a number of different tone arms. We offer plain or pre drilled tone arm boards to make this task easy. The Paris can also be fitted with a clear acrylic dust cover which is sold as an option. We developed the Paris so it can evolve in performance. The drive electronics architecture of Paris being what it is you can up grade your Paris turntable with the plug and play Turbo AC adaptor developed for the Oracle Delphi!

Oracle SME V

Oracle SME V pickup arm

SME engineers, recognising the potential of the latest complementary equipment, accepted the challenge to design and build a pick-up arm which unlike others in existence would make no detectable sound contribution of its own. The work took almost four years and the measure of its success is the acceptance of the Series V precision pick-up arm by technical experts and users as one of the world's truly great audio products.Series V sound has an almost startling dynamic range and neutrality enabling high levels to be enjoyed. It escapes the 'LP' sound and demonstrates that structural resonances in pick-up arms are responsible for much that makes vinyl records readily discernible from master tapes.

The functioning of a pick-up arm appears simple but is in fact very complex. All cartridges employ relative motion between armature and stator portions of a generating system to produce the signal output. Reproduction can only be true therefore when all movement representing groove modulation is made by the armature to which the stylus cantilever is attached and none by the stator represented by the cartridge body. Unless the pick-up arm holds the latter against even the minutest movement at audio frequencies the signal will be modified in some way. The result is a subtle loss of clarity, dynamic range and transient attack that can make the sound from even the best system tiring to listen to.

The following notes will help a better understanding of the problems and how they were resolved in this radically new design.

In common with any mechanical device the behaviour of a pick-up arm is governed by three properties of matter that also define the laws of motion. The first property is mass which opposes any change in motion. The effective mass of an arm and cartridge resists motion least at low frequencies but increasingly as frequency rises. It is this resisting force which makes the operation of a cartridge possible. At subsonic frequencies the armature and stator move as one allowing the slow movements needed to negotiate the record surface without generating a signal. At audio frequencies however the increased resisting force causes the armature to move relative to the stator and a signal is produced. The transition point between these two conditions is important for a clean low frequency response and is established by the compliance of the cartridge and the total effective mass of the arm and cartridge body.
The second property is stiffness which resists bending or flexing. It is a restoring force, proportional to position or deflection.

The third property is damping or resistance to motion. Here motion means velocity and without it there is no damping. The total equation of force acting on a pick-up arm is therefore the sum of three parts: acceleration acting on the mass, velocity acting on the internal or applied damping, and bending or deflection acting on the stiffness.

Mass and stiffness determine how much a pick-up arm will flex and vibrate and damping determines how long it will vibrate. Damping alone cannot prevent flexing or vibration, it can only lessen its effect. The stiffer the arm the less it will flex and vibrate; the more massive the less it will vibrate.

Very high tone arm mass would therefore be ideal to control the cartridge had it not to be strictly limited to preserve the required relationship of compliance and mass already referred to. Stiffness, the second part of the equation of force, must therefore be used also. Infinite stiffness would be ideal but we have to be more realistic. In a beam of given length stiffness is dependent on the material used, its cross-sectional area and in the case of a cylindrical beam increases as the cube of its diameter. Doubling the diameter will make it eight times as stiff.

Although the proportions of the Series V tone-arm reflect these facts, tests showed that the required stiffness was still unattainable using conventional fabricated construction. A one-piece die-casting in magnesium alloy was therefore adopted comprising the shell, tube and balance weight cantilever. 36% lighter but only 25% less stiff than commonly used aluminium, a magnesium arm of the same mass could be as much as 25% stiffer. In addition die-casting would allow the numerous changes of section required to optimise effective mass and control standing wave effects. Finally magnesium's high self-damping factor was augmented with an internal constrained layer to damp the tubes' high frequency resonance.

The Series V's excellent vibration analysis results owe much to the high stiffness and damping of its tone-arm, but stiffness to be of value must refer to something rigid. Tests disclosed the many points at which rigidity could be lost so all other principal parts were pressure die-cast allowing each to be tailored precisely for its purpose and utilising the high mass of zinc-based alloy to damp out vibration. Ultra-high quality 10mm and 17mm ABEC 7 radial shielded bearings were selected to provide low friction vertical and lateral movements, while holding the tone-arm motionless against front/back and torsional forces. The support afforded by these large, wide contact angle bearings, excludes the possibility of chatter and wear or damage in normal use.

The horizontal axis bearings carry the tone-arm in a substantial yoke also housing a spring tracking force mechanism. The bearing axis is at record mean level to minimise warp-wow effect and the spring, a possible source of coloration, is resonance controlled.

The main pillar is 23mm diameter, machined from steel, heat treated, ground and honed. It houses the vertical shaft and bearings, and carries the control bracket incorporating the anti-skate mechanism, lowering/raising control and motion damper.

The base is highly original. The pillar moves vertically between two jaws and horizontally between two slideways. Locking is effected by transverse clamp bolts, spring loaded to maintain settings when released. The design ensures extremely positive clamping maintaining the rigidity of the assembly which is then secured to the mounting surface of the deck with four cap-head screws.

The weight housing is undersung to correct its centre of gravity and provide a vibrationally non-reflective termination of the tone-arm. A damped two-point suspension carries the tungsten-alloy balance weight . Its unique shape enables it to be positioned close to the fulcrum reducing inertia to minimise the effects of record warp and eccentricity.

Movement is made along mitre-ways by rotating a thumb wheel and leadscrew carried in twin ball races. Only l9mm of travel is required to cover the whole balance range and a lever effects clamping in any position.

Electrical aspects received no less attention. The internal wiring is of specially developed silver litz, each conductor having five insulated strands. The damped output-socket swivels allowing it to take up its own position for installation and to minimise vibration transmission when used on a sub-chassis. The high quality linear crystal oxygen-free copper audio lead selected for its electrical and mechanical characteristics is terminated at one end with SME right-angle 5-pole DIN contra-plug and gold-plated phono plugs at the other.

The magnesium tone-arm is finished in satin black enamel, other major parts in black chrome with details in bright chrome and polished stainless steel. Each unit is complete with tools, accessories, and an advanced drill jig/template and alignment system simplifying mounting and exact placing.

Structurally inert the Series V embodies every worthwhile feature in a pick-up arm. As part of a complete system working in concert with a comparable turntable and cartridge it will provide wide range transparent reproduction of vinyl L.P's, bringing the listener audibly closer to the clarity and dynamics of the original performance.
