Kepler and Raptor-Z. (“Z” tends towards Zero)



Kepler and Raptor-Z’s radical styling may be more in keeping with some of the best architecture than hifi but make no mistake this is innovative, state of the art thinking with one aim:

To deliver on a 40-year quest and get as close to the Master Tape Sound as possible.

What other transcription device, irrespective of price succeeds this well, or comes this close to this absolute goal.

Patent protected, naturally, but FIVE patents?!

Johannes Kepler. The man who discovered planetary motion. Three circling “Moons” then might seem the obvious origin to the name. Yes, but there’s more than meets the eye. So, what is it that makes Kepler special?

Planetary motion: Have you ever tried using three arms on one turntable?  Even a contortionist would object. Well, this problem exists no more. Now the name “Kepler” is seen as truly apt. The entire top section – The drive, the three arms, and the suspension – all rotate to bring the chosen arm into comfortable usage!

Speed stability and accuracy: Which is best belt or direct drive? Which handles the “micro dynamics” or the LF weight or…?
The problem in establishing a relevant opinion is that these arguments exist on separate platforms.

Kepler dispenses with that argument by being able to swap between belt drive or Direct drive.

Suspension: Housed in Kepler’s “Moons” is a novel suspension system - like that found in Houdini. Described as 4-pi and with a “virtual anchor”, it is unusual in its ability to isolate equally in all directions, with stability. Just what one needs in a suspension.

The record: Maximum support for records is via a vacuum hold-down using Achromat and its unparalleled energy dissipation for support. We know of no better.

The Tower of Strength: The elegant, compact multi-layered structure owes its existence to the aircraft industry. It is a very rigid support for the drive, platter and arms.




For 100 years, the arm, which carries our signal generator, our highly sensitive micro-seismograph or cartridge, has been the weakest link in the audio reproduction chain.
This is how Raptor-Z solves all those issues.

Zero Tracking error: Using very low tension, the cartridge rotates compensating perfectly as it travels across the disc, its vanishingly low levels of tracking error deliver equally low distortion.
Internally, precision micro-miniature races require watch-maker levels of precision to assemble.

Zero Resonance: Funk’s F.X construction has evolved. Employing a very thin wall, complex, random, internal energy dissipating pathways to cover the entire audio spectrum.
Raptor-Zs beam exhibits less than 1dB resonance. When auctioned it is completely in audible.

Zero Feedback: The more perfect the arm, (which Raptor-Z can claim),the better it becomes at transmitting eternal energy to the cartridge.
Raptor-Z has uniquely been designed to reject such unwanted signals at source.

The blacker the background, the more the colours come through:
Combining all three, Raptor-Z is sonically as black as can be conceived making it a perfect support as it passively transports the cartridge across the record.

Houdini II: In its short life, Houdini has led the way to constraining the cartridge. With an arm as good as Raptor-Z, the requirements now alter and Houdini II’s parameters have been specifically re-calculated and tuned for Raptor-Z, allowing for a further defining of the envelope and a truer approximation to “The Record Cutter in Reverse”.

Kepler and Raptor-Z. Each, the Beauty. Each, the Beast.
They truly define Isolation Bubble, for Bubbles make Beautiful Music.
