Grado/Rega Hum


Unfortunately, I have two analog components that are both notorious for hum.
I have the Grado Reference Sonata cartridge and an extensively modified Rega RP3 turntable.
 Now that I’ve got a subwoofer component in my system, I  hear the hum even at low volume, but only when I get close to the speakers.  Otherwise, I don’t know it’s there.
Is it compromising the final sound?  If so, is there anything I can do about it?
I just added some isolator feet to the turntable and it seems to be doing some good.
( I should probably forget about it, as the sound is wonderful anyway.)

Sleepwalker,

 I have an external power source to the turntable (PSU).  The Rega has a non-detachable power cord.  Also, my preamp has a built-in phono component (Conrad-Johnson PV-11.)

Now that I’ve got a subwoofer component in my system, I hear the hum even at low volume, but only when I get close to the speakers. Otherwise, I don’t know it’s there; that's what you said.

"Otherwise you don't even know it's there".


You do not have a "hum hum" problem, but one that goes with that combination of components; that you only hear when you get close to the speakers; that you did not hear before you got the "subwoofer".

You can either change components, enjoy the music, or spend the rest of your life trying to fix a problem that you didn't even know you had until you got the subwoofer.
