Hum from amp - should I worry?

I recently noticed a hum coming from my Meridian 557 amp. I don't use a PLC, so I wasn't sure if that could contribute to the hum or whether the hum is normal. The 557 is, of course, a solid state amp, so this doesn't seem normal to me. Any advice from current 557 owners? Thanks.

Hey, thanks Tap3 & 7671 - I've been listening closely since my post went up and as you said 7671, the hum is now only audible when my ear is pressed against the face of the amp. When I first heard it, it was audible away from the amp, but it only lasted for a few minutes. Maybe there was a power service problem that morning. Who knows - the amp still plays great, but I just hope it's not a sign of something worse to come. Thanks.

Enjoy the 557. It is a great amp that has been missed by the audio industry!! When coupled to the Meridian 502 pre-amp and 508.24 cd player, it is awesome sounding.

7671 - that's the exact same component set-up I have...you are right, the 557/502/508 combo is killer. Now you've got me curious, what's your speaker/cable combo?
