Whilst hum is a low frequency phenomena, RF interference -can- manifest itself as an audible hum. It depends on the nature of the signal and quite how the device that's being affected demodulates it. Naim equipment, due to the nature of it's design, is particularly sensistive to RF problems, especially high-gain phono stages. That said I use a Naim prefix and have no problems with the SB and it's only a shelf or two away. Try disconnecting the audio leads from the SB to preamp first, to confirm it's not an earthing problem. There are Rf kits available for the Naim bits, but they progressively worsen sound quality as the manuals clearly state. Distance is the best cure if it is RF! Andy. -- Andrew L.
