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.

Some amps are like that. Nothing is perfect so there will always be some noise from any amp - unless the speakers aren't sensitive enough to reproduce it. But hearing it from 12" is kind of loud. I have a tube amp on my speakers and can't hear the noise more than 4" away.

I agree with those who claim 4" when it is really cranked +> thatt is more typical of high end. Nothing is totally silent when cranked...
I'm using an Audio Magic Stealth XXX, BAT VK-D5(tubed output stage), TacT RCS 2.2X, Cary SLM-100(tubed monos/mains), Hafler TransNova 9505(woofers)and my system is dead quiet with your ear against the Main speakers. I'd have to say there is a problem with your power amp, OR: There is the possibility that your CD to Naim interconnect is picking up RFI/EMI do to routing. Try disconnecting it and listening for noise. Are you using a power conditioner/upgraded A/C cables? Could be hash on the A/C too.
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 dont know about any of you, but I feel that true Hi Fi components should not hiss, hum, or create these types of distractions. Is that too much to ask?
