It is a sound that will not change with the output volume of the speakers. It is similar to the whisper you hear when you put a glass in your ear, it seems as if you heard the wind from afar.
My wife says it's a normal sound because the piano is alive. For her it is almost imperceptible. I may have obsessed too much. Doclad Even if I set the volume of my CA98 to the maximum I get zero hiss/white noise through speakers or headphones. So, your unit does not seem to be working as expected. Have you tried reducing the line in volume to zero as suggested? By the way, what happens if you save a couple of seconds of silence using your cs8 to a wave file and then listen to the result (or look at the sound wave) on your computer? It should have no noise whatsoever. This would also mean that your unit has some kind of electrical interference getting into the amplification circuits.

I can tell you have great trouble shooting skills but all amps with speakers have a background noise level typically and it seems the OP is just hearing the idle hiss. It sounds like two or three different issues and problems are being mashed together. I know this thread has run it's course but I just wanted to hear from the OP if he had tried HIGHR Impedance HP's.

I agree with you! I have a very good set of hi-fi speakers and amp and there is always background hiss on that system. But on the mini hi-fi system I have connected to my PC via optical spdif there is no hiss. The same applies to my CA98. Note that the ca98 has a soundboard with two transducers along with 2xmid-range and 2x tweeter . Maybe the hiss is concealed by the cabinet. But I cannot hear it.
