Noise in one channel


Newbie here, both to the forum and to high quality home A/V.

I have a two year old Emotiva Fusion that was never used.  I just purchased KEF Q300 and Q600 and have some old Onkyo surrounds.  

Upon install, I have been hearing intermittent crackle/pop sounds from one channel (FL).  I assumed I had compromised speaker wire somewhere so to confirm I swapped Center and FL channels at the receiver.   The sounds followed the swap and began emanating from the Center channel.   I believe that points to the amp circuit from the receiver, does it not.

What are my options to fix or further isolate this?

thx,
Stevie

Does this noise happen at any volume, low, medium, or high?

"any others that compare in terms of spec vs price?"

That can be very costly and lead to a bad purchase if you don't fully understand how to interpret them. IHMO, they are more useful to rule out a choice rather than make a buying decision.

I meant are there other entry level audiophile grade amps in the price and spec range of the Emotiva A500.
Appears the Fusion needs to be sent to Emotiva for service.

If the plan is to connect the A500 to the Fusion, that doesn't make much sense to me. Even if the Fusion is working properly, if there is a difference, it would likely be marginal, and there's a good chance for no difference. Also, that may or may not resolve the noise issue. That type of noise may not be in the power section of the Fusion, but elsewhere.
