Any unused input sockets on your integrated or pre-amp can allow high frequency noise to influence sound quality by polluting the sensitive input circuit with RFI noise.

 If you have an amplifier  with DIN connections, you can prevent that problem arising by simply connecting a PHONOSOPHIE DIN Shielding plug to each unused input -  not the outputs!

The benefit is reduced distortion of the signal and lower background noise.

These high quality DIN plugs  are hand-built in Germany to exacting standards. They are perfectly suited for use on DIN equipped Naim and Quad  amplification as well as the full range of PHONOSOPHIE equipment.
