Oracle Delphi mk VI Ref.

The Delphi Mk VII Reference is equipped with our new Mk VII Reference granite base. This new granite base is thicker and heavier than any other previous granite base that Oracle ever offered. With its weight reaching just a little over 38 pounds the Delphi finds itself better anchored to its environment and this translates into a significant sonic performance increase! The whole spectrum of the music becomes more detailed and the imaging gains in perspective and clarity. The low frequency range of the music gains a lot from this upgrade; there is more authority and volume to the bass which results in an overall better tonal balance. Those who experienced the Reference granite base have described the change as amazing and astonishing! Note: The Mk VII Reference granite base is available as an upgrade for existing Delphi Mk V and Mk VI turntables. Since the introduction of the Delphi Mk VI in the fall of 2009 featuring the innovative Micro Vibration Stabilizer System (MVSS) we never really stopped with new developments. During the summer 2015, we introduced the Mk VI Second Generation featuring the new two-piece platter assembly which greatly facilitates the drive belt installation while also reducing platter resonances. By not having to remove the inner platter to install the drive belt the main bearing accuracy is preserved. With a now lighter inner platter/spindle assembly we were able to further improve the main bearing design and make is calibration even more precise. The trust plate supporting the platter spindle Tungsten carbide ball tip is non-metallic and made of Glass Filled Torlon. The dual tripod main bearing design is using 6 precision PEEK screws, 3@120 degrees apart at the top and 3@ 120 degrees apart at the bottom of the bearing assembly, those are offset @ 60 degrees with the top screws. The AC synchronous motor uses impedance matched internal windings. The Mk VII motor drive module is a precision frequency generator using Military grade high precision capacitors to further smoothen the sinewave feeding the motor coils. A precision calibration stage has been implemented to the drive module so we can precisely adjust the positive and negative sinewave voltages feeding the motor coils further reducing vibrations. The final and key element of the new Delphi Mk VII is the Turbo Mk II power adaptor which has been further improved. A fine trim potentiometer allows a precise calibration of the output voltage to 24.35 volts DC. The elaborate drive system of the new Delphi Mk VII has been designed so each critical steps can be precisely calibrated to aligning with a very high level of accuracy with the ultimate goal being to make the AC synchronous motor spin smoother and more accurately with less vibrations. All the settings described above are done at the factory so our customers do not have to worry about them, the main purpose of the Delphi Mk VII is to provide to you the user with pure visual and musical enjoyment.
