"White noise hiss" through speakers.


Hello fellow music lovers, I have a newbie question so be gentle with me. I replaced my Creek 5350 with separates. I’m now using a Belles 21A Preamp with a Musical Fidelity A308cr. When I used the Creek, I could turn the Creek up full volume, and with no source playing there was not a single hint of noise through the speakers. Now, with the Belles & MF there is a faint hiss audible at 2 feet or less even with the volume at zero. Needless to say when I turn the volume up (with no source playing) the “white noise hiss” increases noticeably. Is this normal with a high powered amp? The MF is 225 watts per.
The speakers are Spendor S9s.

Any input is appreciated, THANKS!

This drives me crazy. It is something of which every component has a little. I would switch out the preamp and see if it goes away, otherwise it is the power amp, which I used to own and found very quiet. I once bought an ARC LS 15 pre which is well regarded. It hissed much worse than thhe 150$ Carver that it replaced. It did other things better but I could not get over the hiss. My deale said that thit was prt of the design, to get the detail and imaging it needed a higher noise floor. I returned it. In the cases it usually the pre
