Here's some additional information from the manual:
"Inputs are selected through a logic operated relay circuit to keep signal paths as short as possible. The relays used are twin gold contact bifurcated crossbar types with a contact resistance of less than 0.05 ohms, and are chosen for their non-invasive handling of the incoming signals. The single ended phono connectors are all high quality individual, gold plated connectors with Teflon inserts. The housing for the electronics is designed and precision engineering from high quality aluminium in our own manufacturing facility in England."
