Hello Guys, I just register here couple minutes ago. I'm looking for right amp for my set up.
I Do own:
Denon X4000 receiver (up to 7.2) set up.
Klipsch RF-82II's , RC-62II , RS-52II's
Dual SVS PC12-Pluses
I'm looking to add in future rear surrounds and front height to have my system 9.2 so question is what kind of amp to get. I know Klipsch speakers are very easy to drive so is there any benefits to get let's say XPA3 and run 3 main speakers or XPA5 and run 3 mains + 2 surrounds and have receiver handle rest or leave it all on receiver and maybe get just UPA-200 for 2 extra channels what my AVR can't do?
Thanks for responses Pavel

Pretty much any combo of Emotiva amps will improve the SQ, punch, impact, etc. over what you currently have. If you run anything off the receiver, I would run the least used channels, the heights. Get a separate amp for your mains and center and surrounds. Some combo of an XPA-2, 3, 5 or find some used UPA-1, 2, 200, etc. As I said, all of their amps are good. Depends on your budget and space.

XPA-7 is coming out soon, too. Depends on how many channels you want to amplify.

If you MUST have a big amp get an XPA-3 to drive the front three - thats the most important part of the sound stage. The rest can be driven by the Denon just fine. Otherwise add a UPA-700 and let the Denon drive the rest.

From memory the X4000 only handles 7.2 so I'm not quite sure how you are intending to go about getting to 9.2. I don't know about the other guys but I don't have enough information to really give a suggestion on power amps. Like, is it only for HT? Or do you do some stereo music listening? What sources do you use? What size is the room? Furnishing and/or acoustic treatments? How soft/load volume do you like to listen at? Pretty much any additional information, especially the budget, will help narrow down the choices as there are a lot. Keeping in mind that there isn't a bad amp in the Emotiva range, not that I've heard anyway. So any one or combination of them will do a great job for you.
Cheers
Gary

Do you think UPA-700 will be enough for those speakers or is better to get big amp like XPA3 or 5? I really don't think I need to extra amp front heights and rear surrounds so maximum will be 5 speakers or only 3 main one. I called Emotiva today and Guy said if I will get let say UPA-700 and use only 3 channels some power from rest of the channels will be adding to main 3. I don't know if this is truth or not. |

Cheers Gary The X4000 has a 7 channel amp but processes 9.2 if you add two channels of amplification. |

XPA-7 is coming out soon, too. Depends on how many channels you want to amplify. Thanks for response, UPA are 80W per channel and XPA's are 200W per channel so you think for Klipsch speakers UPA will be even better then Denon X4000? |

Garry Cook hits the nail on the head my new found friend!! All of his points should be considered and shared with us in order that we can be of help.
The more you educate us about your wants/needs your room, and all he asks the better we can serve you. Friendship is about serving others, I hope you are a new friend on the forum.
Always great to meet new people and friends. Welcome, kick your shoes off and stay awhile.
I have similar Klipsch and I have a great amount of headroom that is apparent when driving them to great db s. Much more controll of the speaker ,,especially in two channel.
Nick

Cheers Gary Hello Gary, well I do 70% movies and 30% music. Yes i do some stereo listening music for sure. Sources you mean like for movies I use PS3 now. Music I have a lot of CD collections and I stream a lot music over internet. Room is now only 16x16 and with open kitchen on one side but I will later move to bigger room max 23x16.I know budget is a question but i'm looking it like this. My Klipsch speakers RF-82II's, RC-62II, RS-52II's are not the best but also not bad. It is same then I bought my dual SVS subs recently. I had at home 3 sub from them in one time pair of PC12-Pluses and PC13-Ultra so I listen them, compare and I really like dual subs but don't want to spend $$$ for second Ultra so it is why i kept dual Pluses (they are also not best but definitely not bad sub at all) a specially when I came from Klipsch 12 sub.  . So it is something with Emotiva I just want some amp what can get the best from my set up. I just bought those speakers so i will kept them for a long time for sure. I had before synergy line for over 7 years and sell it and start buying Reference line. Pavel |

I called Emotiva today and Guy said if I will get let say UPA-700 and use only 3 channels some power from rest of the channels will be adding to main 3. I don't know if this is truth or not. Take a look at your speaker's efficiency. Frequency Response: 33Hz-24KHz ± 3dB SENSITIVITY: 98dB @ 2.83V / 1mPOWER HANDLING: 150W RMS / 600W Peak NOMINAL IMPEDANCE: 8 Ohms compatible The sensitivity (98db) means at one watt/2.83v at one meter your speakers put out 98db of sound. For each 1 meter back subtract 3db - so at a listening distance of 3 meters your speakers put out 89db. You'll need 4 watts to get back to 98db. Reference level is 85db and most people think that is too loud. 98db is more than enough to cause deafness if listened to on a regular basis. You can do the math - for every doubling of power your speakers (any speaker) will add another 3db of volume. Unless you have a very large space and you like to listen at high volume the X4000 is likely more than enough to drive those speakers. If you have the $$'s then by all means buy the biggest baddest amps that catch your fancy. But be prepared to be disappointed when that new amp makes little or no difference. For 9.2 output you will need at least one stereo amp - the mini-x100 would be enough to drive most height/width speakers. Many posters here remark on what a difference adding an external amp makes - just remember its all subjective. Let your own ears be the judge. |

Nick Thanks Nick, it is nice to find forums like this one. Well actually AVS forum and talking to people was a big reason why I also start thinking about change my current system. It is always helpful to find people who already have experience like i did with Klipsch speakers and i also safe a lot of extra $$$. I never tough I can buy those over the phone for completely different pricing. So what amps are you using? Sorry my English is not perfect I'm originally from Czech rep but I live 11 years in SC. |

He said if I will get UPA 700 model and use only 3 channels other 4 channels wats will add more watts in 3 channels what I will use. |

Thanks for response, UPA are 80W per channel and XPA's are 200W per channel so you think for Klipsch speakers UPA will be even better then Denon X4000? Depends how loud you like to listen. Your front speakers are rated for 600 W peak power and that's where big amps come in, for musical peaks that can require large amounts of power. I don't think 200 watts is out of line for at least your front three speakers, even if they are rated at 98db. |

Yes, you will get more power out of a UPA-700 driving only three channels, because all channels share the same power supply. If I had to guess, I would say around 125 watts per channel or so. |

Thanks for fast responses. To get more power out is also same for XPA models? Probably yes right? Well it is nice to know, maybe UPA model will be perfect for me or XPA3 it is where I'm now. It is work like this also for receivers? Let's say if my 3 mains will use XPA3 my receiver can put more watts per channel to rest of the speakers than if all speakers are using only receiver,right? |
