    DIY Parts

     

    CLK-R - Low noise regulation / filter circuit. Ideal for clock and / or digital supply rails.

     

    CLK-R low noise regulation circuit

     

    Clocks - Timing is the essence of musicality & without an accurate clock in your player you will never hear the original performance..

     

    C2 low jitter premium clock

     

    SPower - Hearing is believing! Low noise, fast response voltage regulators. The SPower benefits from a very low noise precision voltage reference point...

     

    SPower low noise voltage regulator

    The worlds greatest SA-11S2! ......probably!

    This upgrade can be applied exactly the same for the SA-7S1
