I can't do much about the speaker positions. I wish I could pull it out more, perhaps when the kids are grown bigger to understand how much daddy loves his sound/music and they shouldn't be playing around it. If I pull it out now, the kids might be bumping into them like crazy and the last thing I want is for it to tip over. No no no Jesus no!!!! I'll commit suicide  I'm just a little surprised that someone who was so adamant about a minor hiss/buzz from less than 1 foot away has his speakers positioned so sub-optimally. I understand about limitations due to little kids since I had 2 (now the younger one is almost 9 so it's ok), but I'm the opposite I guess. I can live w a little hiss but It would be tough to live with speakers positioned like that. So with all due respect regarding toe in, does it really matter? How do you expect to achieve optimal imaging? The hiss and buzz is amplifier related. Not speakers or its position. Now if you can guarantee me that the hiss and buzz will disappear forever if I positioned my speakers optimally, I'll give up my kids for adoption. |

Hey guys Regarding toe in. What's the best way to judge how much is too much or too little? First you get them away from the back and side wall facing 90 with no toe in. Move them until it sounds best to you, cancellations, soundstage, boominess etc. Once you have the position down you start toeing them in step by step just as you did before when you positioned them. Some part is personal due to how narrow you want your sweet spot to be vs soundstage but you'll notice when you've gone too far. The sound sort of falls apart. That's how it is for me at least. Brand, That's what I did when I first set it all up. I positioned them so the tweeters are pointing towards the direction of my ears while sitting in my main listening position. I'll toe it out and see if there's any improvement in sound. I kept both speakers equidistant from the edge of the carpet. |

Sit in your chair and place the speakers poolside,,,,,,,,,,,,there,,,,,no hiss,,,,,he,,,,,he,,,,,he,,,,,,, the better sound will distract you from any hisssss place optimally and mark the floor somehow and place back by the wall. when you have a private moment, place speakers optimally and enjoy, then place your seat back,,,,,oh wait,,,,never mind!!!  |

Perhaps if there's some sort of wheeling mechanism base that's designed for speakers, it might work for me but at this point in time, safety and security of persons and property takes precedence. I'm happy with the sound as it is, the benefit:risk ratio of moving them 3 feet from wall is simply too great for me. But I do hope to find a solution sooner rather than later.

Things that may cause buzz or him in your amplifier.
1) the first thing I would check are your rca interconnects between your source component and your amplifier. This is the very first thing you check because a loose connection and improper grounding will cause a humm sound from my experience.
2) after testing your interconnects and experimenting with different interconnects I would check to make sure your not doing anything weird with your speaker cables. If those are loose or crossing over each other especially with five channels you might be creating emis that are affecting your sound quality.
3)the very last thing is your channel inside your amplifier are not properly grounded or shielded which would require the manufacturer to investigate. Its your job to eliminate the other possibilities first through experimentation and trial and error. There have been so many times that do to my poor setup I've caused humm in my own systems. Having 5+ channels just complicates things even more.

I sure understand that, my kids are always danceing around the media room when music is on. I will say that your speaker placement is less than optimal but .... And your buzz issue from the amp (if it truly is the amp and not a dirty power issue or alike) is unacceptable from a xpr lineup in my opinion. In fact this buzz from a xpr amp is far more rediculos than spending 5k on a amplifier. |

Eight pages and nothing has been accomplished, therefore I will add to the madness by not adding anything at all..

The fact that the problem still exists after ruling out all other extraneous possibilities reflects poorly on the manufacturer, not the consumer. But like I said previously above, the xpr/803'd combo is sounding better and better everyday.....even the buzz and hiss is sounding sweeter and quieter. Perhaps it'll auto correct itself with many more hours of burn in time ehhhh?
At the mean time, can't wait for my kids to grow up so I can pull my 803d's out where they belong!!!
Wait a minute! Do I really want them to grow up??? That'll bring a whole host of other problems.....boy friends??? Noooooooo

The hiss/buzz is audible from 1 foot or less. This is good information because it's considered normal by emotiva and several of us owners. However, it's not universally accepted and if you fall into that camp then now people know that it may not be for you. 2. To achieve optimum performance from speakers you have to place them properly. You may be in a situation where it's not yet possible due to fear of having your speakers damaged by your kids. At least being aware of this is good. I think this thread helped a lot of potential XPR buyers. |

I have been reading this thread because I have been having some buzzing/hiss in my setup with a umc1 and xpa5g1. Now originally I did not notice any noise, but recently I have noticed a pronounced hiss immediately after turning the system on. The xpa5 is plugged into its own outlet and is triggered by the umc1, which is hooked up to a Furman 1500 something. I notice that the buzz/hiss is pretty strong when the amp is triggered, but the Furman has not turned all the way on. Once the Furman is on, its drops a few notches to be acceptable, but more than I think it used to.
I too agree that a tiny bit of hiss when your ear is right up to the tweeter is normal, but anything that you might notice in a dead quiet environment from more than a foot, is probably a problem with some wiring or interference. So I think I must have repositioned the setup so many times that the cables in back must be jammed up. I am considering rewiring and routing everything away from the power cables, but I have tried disconnecting the rca connections on the amp and there is some noise still, but maybe a but less. I realize that my speaker cable is very close to some power cables, including a 220 line for a welder (this set up is in a garage workspace, great acoustics and capable of being very dark, have a plasma in there.
I guess I am wondering if I'm totally OCD, or if a complete rewire is appropriate. Would be very happy to solve the issue, but would also be very bummed if I took the trouble and couldn't resolve.
Would love to hear your input, thanks.

This thread may not have solved the buzz/hiss issue but potential buyers who comes across it, would be much informed of what to expect before plunging blindly into an Emotiva product. I certainly would appreciate the info. This is the free market at work.
