Help with system/ARC noise

Hi there!
Im new to this hobby and started to build my sytem. Currently i have an audio research ref5se preamp/ARC DS450 amp/B&W804D.  I hooked my oppo 105 to play CD and audio streaming using pandora. The problem is I'm getting noise and sometimes a loud pop of noise. I'm using audioquest yukon entry level xlr interconnects. All units are connected in individual wall ac. I called ARC and they said ARC ref5se and DS450 amp are compatible and should have no impedance issue and they already paired it before. I already isolated signal cables from power cables. My next step is to get a power distribution/conditioner and see if this will solve the problem. To old timers in this hobby:
1. Did you encounter similar problems and how did you guys solve it?
2. Any experience/suggestion on power conditioner to match with ARC with good result?
3. When hooking digital players like oppo or any cd player do you need to have a DAC unit even if the player has a built in DAC?

Any input is highly appreciated.

Biggiglypanda,
I was researching the oppo dvd players recently, and vaguely remember reading posts about the 105 popping issue. I think it had something to do with a firmware issue and certain ( digital ) inputs. I believe there is a downloadable fix for it. Try searching of the more video specific sites ( like AVS). You might find the answer you're looking for there.

best of luck!

I'm not sure if you have any hdmi cables connected to the oppo ( to send video to a tv perhaps?) if so, try disconnecting all hdmi cables before tracking down a separate CD player.
