Is your Pass X250 dead silent or slightly buzzing?


Hi
I noticed that when i stand near my X250 about a yard away i can notice a slight electrical noise when it is in standby mode or powered up.All the amps i had before were dead silent,even though they were class A/B designs.Is it somehow related to class A circuitry or do i have a probvlem?I can't really call it a transformer hum,more like you're aware that there is ekectricity inside.The closest i can describe the sound is like if you listen to a regular tv on mute or a computer CPU when it is not accesing it's hard drive.

Try a PS Audio Humbuster. You might have DC potential riding on the AC. I had the same thing with my Pass-designed First Watt amp, as well as other amps I have used. A small problem that nagged at me. PS Audio has a 30 day money back policy so, why not give it a shot. It took care of my mechanical xfmr hum. Ahhhhh!
