Low Jitter Clocks

Fidelity Audio C3 Premium Clock

The C3 uses a custom circuit based around the Spower "D" discrete low noise voltage regulation. This enables the clock to perform to a very high standard which WILL outperform clocks costing 2/3 times more. "That C3 effect" Many customers have realised no matter what the C3 clock is fitted to the effect on the music is always a wonderful analogue presentation with details and timing they never thought possible "Timing is the essence of musicality and without an accurate clock in your CD player, DAC or music server you will never hear the original performance as it was intended"

The superb C3 has a very low noise power supply. Using the same technology as in the SPower "D" discrete regulator allied to a improved circuit layout. The C3 provides the ideal replacement to the manufacturers clock in your CD / SACD / BLURAY & DVD player that offers exceptional timing and detail allied to delicate treble reproduction and extended bass.

The power supply is everything..........

From component hop ups to the custom quad DAC design incorporating swiss 384Khz Anagram Edel upsampling filter with sonic scrambling.

Following the success Fidelity Audio SPower, the HiFiSounds linear FET output regulators and clocks now perform exceptionally well. With the successful DAC chip testing utilising the Audio Aero 192Khz STARS processor, work is now well underway on the test dual and Quad DAC 384Khz upsampling unit.

The amplifier is a product of many years development and has had the interim appraisal and technical advice of Martin Colloms, one of the United Kingdom’s top Electro-acoustical engineers.

The GVA-30 is designed and optimised to drive most modern high quality loudspeakers and being free of Global Negative Feedback provides a natural, accurate and dynamic response giving rise to a superb audio performance.

Each amplifier runs two pairs of KT88s as Triodes in class “A”, driven from a cathode follower and balanced phase splitter to provide 30 watts RMS power at clipping, more than enough for domestic listening. The output valves operating as triodes keep third harmonic distortion to a minimum and maximise loudspeaker damping. The power supply uses two GZ34 rectifiers for longevity and reliability.
