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.

Update:

I reset my oppo to factory settings and download/update the firmware. So far I played CD playback for about 3 hours now and no loud popping noise. I hope it won't comeback.

When the oppo is on standby I can hear low hum on the speakers but only if I put my ears directly to the speaker.

With this development I plan to leave alone my oppo with my home theater set up and just invest in a separate CD player/DAC or a music steamer/DAC for my digital music.

Second: Invest in a power isolation/purification equipment to further reduce noise.

Third: work extra to support this addiction and the never ending list of equipment to complete my system lol!

Thank you so much for all your suggestions. It was a lesson for me and a lot more to learn.

 

jafreeman: can you please educate me more on how to improve my power supply to further reduce noise. I check the Richard Gray products and I'm not sure which one to get. There's a power isolation/purification equipment and a Parallel power delivery equipment. Do you need  to combine both to enjoy the benefit?

There are so many products out there and i got dizzy already reading reviews which are all very promising. (not sure if its painted or real results).

I want a unit that is truly functional but not utlra expensive.


big, Power conditioners are a complicated topic. Some people swear they result in a big improvement others say they hurt the sound quality. There has to be a good match between system and conditioner.

You seem to be very anxious to get your system sounding great but this is something that takes time. If you’re in too big a hurry you can waste a lot of money.

Now that you have the Oppo working with your ARC, take some time to familiarize yourself with the sound of your system. Move your speakers around a little bit to see if that makes an improvement. If it sounds great just listen for a while before any more purchases and read up on audio in general and individual products.

Make sure you like your speakers, the biggest difference in sound in components is between different speakers. Once you’re sure you have the right speakers, start figuring out where you might best put your money to improve your sound.

On Amazon you can buy "Get Better Sound" by Jim Smith or "Introductory Guide to High-Performance Audio Systems" by Robert Harley. These books would probably help a lot in getting your system to sound the way you want it to sound.

If you decide that you want to start experimenting with power conditioners, power cords, interconnects, speaker cable, etc, check with The Cable Company who will give you advice and let you try out different cables etc. for a price. They may save you a lot of time and money in your search.

In the end it’s about listening to music and not about buying gear, so take your time and enjoy what you have before deciding what to buy next.

Welcome to this fine hobby and enjoy your music!


Tomcy6:
 Point well taken. At this point I am running out of wall socket to plug all my equipment so i'm planning of getting a power distribution box that will also serve as conditioner. 
The oppo seems working well now so your right- i'll enjoy it first. I read in some forums about using their oppo as DAC and hooking a mini mac as media server.

Any suggestions?
If you plan to keep the Oppo 105, checkout getting it modified by ModWright.    I think Oppo 105 supports DLNA so you can run DLNA server, ie JRiver, on a computer and use the Oppo as a DAC.

From my experience, I suggests adding dedicated 20 amp lines just for audio, upgrade your AC outlets with Furutech's GTX-DR-NCF Receptacle and get a power conditioner or power distributor.    

As tomcy6 mentioned, power conditioners can be tricky.   I've had many and prefer a power distributor Weizhi PRS 6.  My brother has a Shunyata Triton and he loves it.    Have heard good things on PS Audio P10.

Once you have a good foundation, try different PCs. after market fuses, IC and SC ... 

You already have a good amp, pre and speaker so off to a good start and no need to rush.
