The problem is most certainly with your preamp or your amplifier.
Loudspeakers cannot reproduce "hiss" when none is present within your amplifying system.

I would say you should check out the wires as well. I know others have mentioned this, but try moving things around a bit while you hear the hiss. Try moving wires or moving components around. Could possibly be a loose connection, but that would most likely buzz. I doulbt it's the speakers.

One other thought is that it could be from something else on the same electrical circuit. Good luck with it.

As I still don't quite know what to do I've also started a thread in the class-d section.

But I've connected the t-amp to another set of speakers (traditional two-way stuff) and there is no more hiss than when I'm using my other amps...

Argh...

The source. CD player. Tape deck. Preamplifier. Source of signal to the amplifier. Change it.

Ok, I am gonna go out an a limb and bet it's the source. I say this simply because he already switched amps around and still had the problem.

We know it's not the speakers, BUT they could be a bit of a "culprit" here I think. Not havig played with the Audio Nirvana speaks I cannot say for sure but they appear to be like Fostex "sound-alikes" which means they may tend to have a bit of a forward mids and highs ("hiss" frequencies). This forwardness, may be just magnifying the "lesser" hiss you hear in your other speakers.

To recap, he has switched amps and speakers out, eliminating these as the source of the problem, what's left? Source or preamp...no?
