The Gold Digger is a switching device that is void any form of buffering while employing the absolute minimal number of passive components in the audio signal path. The result is exceptionally linear performance at all frequencies, phase and distortion measurements that are below our test equipment capabilities and a resulting signal-to-noise that exceeds 140dB. This confirms the claimed ‘straight wire’ performance and gives complete assurance that the Gold Digger will not add not color, distortion or introduce artefact into the signal path.
