white noise from tweeters

I recently purchased a Naim CD5i CD player, Naim Supernait amplifier and B&W 805S speakers. Using Cardass Crosslink for speaker wire.
I have an almost inaudible, I have to be within 12", white noise coming from the tweeters. This doesn't affect the great sound coming from the system but it does annoy me.
The noise remains after disconnecting the CD player and it is not affected by increasing the volume. I'm certain this noise is generated by the amplifier and I'm curious if anybody else has experienced the same thing.

I contacted Naim and they responded very quickly, see their response below.
I'll try different speaker cable and "listen" to what happens.


This white noise is perfectly normal from our amplifiers, what is the specification of the speaker cable. Our amplifiers do not have inductors in the output and therefore the cable forms part of the output circuit of the amplifier, NAC A5 has a resistance of 9 milli ohms per meter and 16pF per meter and we recommend 3.5 to 5 meters per side for optimum loading and performance.

I've tried different speaker cables and have the same result, the "white noise" remains. This noise does not change in intensity as the volume is increased and is always present even with no source connected.
I suppose I'll have to live with it, not such a big deal since at listening levels you can't hear it and the music sounds great. Thanks for all the input.
