We developed a 1:30000 Cryogenic Current Comparator for SET current amplification. A dedicated low-noise, directly-coupled SQUID was used for the readout, which allowed reaching a sensitivity close to ideal. The ratio error was <9×10-9. The CCC-SQUID equivalent current input noise was 3.0 fA/Hz12/, measured down to 0.1 Hz.
