Noise coming from speakers

[ManishKasera]

I have my Parasound Halo A21 connected to pre-out of my Yamaha RXV-2500. Parasound's power plug is connected in my Monster power center in amp section.
I'm noticing a noise coming from speakers when AMP is on. If I remove the Amp and connect speakers directly in RXV-2500 there is no noise.

I'm connecting my Paradigm Studio 60.

This noise makes me really mad as A21 is such a great amp and this problem.

So I have two questions here:
1. Does his noise is harmful for speakers (tweeters, woofers etc.) in anyway?
2. How to get rid of this noise?

Any advise from your experience will be really appreciate.

Looking forward for help from all pro's out there.

What kind of noise?

Hissing noise?

Adam should be moderator, but would he WANT to be?

Would that add pressure and make things less enjoyable personally?

I think no Audiophile can be called a moderator At least in the moderation sense.

I have a Parasound HAC -1000 amp and my hum was coming from my TV cable. Unplug or disconnect one component at a time from the system and when the hum disappeared you will know where it is coming from. After you find out the source you can begin the fix. It might be replacing a three pronged plug with a two prong adapter to eliminate the ground hum. With me it was the cable box. After I ran my cable through a power conditioner the Hum disappeared.
