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.

Tomcy6-i will do everything possible based on your input. Thanks

jafreeman-a power source would be similar to a PS audio PS10 powerplant? My listenning environment is just a typical living room but nothing is running except for the system when i experienced the problem

Yes, the PS Audio regenerators appear to be very nice sources, although a bit spendy compared to the other brands that will supply more power than the PS10. See if you can first place a dedicated, 20A line, which will supply 2400W, but that is only one duplex outlet, so will need more.  The PS units have the outlets, but need to have enough output for your system, or part of it. You could plug the amp into the wall, the front end into the outlets of a smaller PS unit.  Most here would say not to plug amp into transformer, which would limit dynamics.  You can do that, but will need one with more wattage output--similar to the 20A line.  You have a fairly large system that can produce a lot of work at high volumes, and this usually calls for more power.

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!

Yakbob-thank you for the heads up. Now i'm seeing hope lol! I will try to get a dedicated cd player and see if it will make a difference

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.
