Let us know if you hear a difference. If upgrading the power cord on the XPR 5 reduces or get rids of the noise/hiss/buzz, that alone would be worth the few hundred bucks I'm willing to part with. Not thousands. About 10% of the value of the XPR should suffice. Stock power cords used with my XPR-5 & XPR-2, no noise/hiss/buzz that I can hear. Wish it was true for me. |

XPR-5 internal wirings.... open the unit (and your mind) and see...(HINT: red in color) what's the point of having an 'UPGRADED' power cord....  btw…. that is the internals of an XPA-5, not XPR-5. tchaik……….. |

Wazzzup my audio bros Hey I'm looking to upgrade the power cable to my XPR 5. Any recommendations? Thanks To gain TRUE audiophile quality, stay in the 12 to FIFTEEN THOUSAND DOLLAR price range. That will provide you with the necessary dynamic range and soundstage. NEVER use the original power cord that comes with the unit. the molecules are never properly ordered. Hope this helps.
Bill

Wish it was true for me. stanlee If you are experiencing noise in your system you may have a bad connector or a bad wire on one of your interconnects. You may also look over all the wiring in your system and separate your power cables and interconnects as far away from each other as possible. After all this if you still have noise then you may want to try a more insulated power cord or interconnects. You may have a ground loop problem and upgrading the power cord will most likely be money wasted. Can you give us more details on your issues ? There is a plethora of knowledge on here and many people that would be willing to help you isolate and get rid of the noise. |

I hear noise from my speakers with nothing connected to the XPR 5. Nothing. Just XPR plugged to the 20 amp wall outlet and connected to speakers

Mshump I hear noise from my speakers with nothing connected to the XPR 5. Nothing. Just XPR plugged to the 20 amp wall outlet and connected to speakers Have you tried the Amp connected to a different outlet ? What speakers are you running? Is the noise on all speakers or just certain ones ? You can also try a cheater plug on the power cord where it attaches to the outlet. |

Why do you believe the power cable is making noise? My XPR-5 is silent. I let my wife listen for static noise, or audio buzzing. She has remarkable ears. She hears things I say when I don't say anything.

There's only 1 dedicated 20 amp outlet What speakers are you running? 803D's Is the noise on all speakers or just certain ones ? Both L&R You can also try a cheater plug on the power cord where it attaches to the outlet. Cheater plug? |

The only possible "upgrade" a pwr cord could make is if the Gauge is increased, period. It's not rocket science and that last 6 ft of copper wire will make ZERO difference.

Both L&R You can also try a cheater plug on the power cord where it attaches to the outlet. Cheater plug? You can run an extension cord to another outlet in your house (not on the 20 amp circuit) to see if there may be a problem in the 20 amp circuit. As long as you are not cranking the XPR-5 to blistering levels it can be hooked up to a 15 amp circuit so doing it temporarily for troubleshooting will not damage anything. You can try the cheater plug to see if there is a ground loop problem.  If that doesn't work I would call Emotiva tech support in the morning and talk to them. They sell the CMX-2 and CMX-6, I have never had any issues,so I am not real familiar enough to know if one of them would help you, but they may be able to help you if one of those might help fix your noise issue Keep us posted please on your findings. |

Stanlee- "I hear noise from my speakers with nothing connected to the XPR 5. Nothing. Just XPR plugged to the 20 amp wall outlet and connected to speakers"
Get a true RMS DVM and measure Neutral to Ground at your outlet. In reality it should read 0V, but anything less than 0.5 Vac SHOULD be ok. If you read 1.0Vac or more you have a power line problem- under gauged wiring or neutral & ground terminating in the breaker box. Many electricians will use Neutral as a ground and say they're the same. Wrong. They are different until the lines are terminated at earth ground using a copper grounding rod. Are you sure the breaker box ground bus is earth grounded?
You could be getting noise from a power supply of lower quality- ,maybe a laptop/HTPC or even something in another room that is plugged in but not turned on.
I have big issues listening to AM radio due to crappy pwr supplies or light dimmers.

You could try a decent power line noise suppressor - which should stop anything coming in through the power lines. (Make sure you use one that actually does filter line noise; not all surge suppressors are also NOISE filters, although a lot are. Our CMX's are excellent noise filters.) It's also possible for RF noise to be picked up by the speaker cables, or even by the speakers themselves, and find its way into the amp that way. If that's happening, you could try shielded speaker cables (although you can't really shield the wiring inside the speakers), but even relocating the wires, or simply rearranging them, may help.... things like moving your cordless phone base station to another outlet, or another circuit, may also help. Often you can get a hint of what's going on by listening to the noise..... Does it sound like voices? Does it only happen when your cordless phone is off-hook? Does it only happen when your computer is on, or during the hottest part of the day when everyone's running their A/C? Stanlee- "I hear noise from my speakers with nothing connected to the XPR 5.
