Need help with amplifier for my Klipsch surround upset

[Mac78]

Hi, im looking for help to get some more power for my surround by adding an amplifier and wonder how much power i need for my speakers

My setup is :

Receiver  : Onkyo TX-RZ810 B 

Amplifier : adcom 7705

Center     : Klipsch rc64 II

Front        : Klipsch rf83   

Surround : Klipsch rp250s

Ceiling     : Klipsch rp140sa

Sub          : Klipsch R-112SW

I was wondering if i could use 4/5 channels on the adcom 7705 for my Klipsch rf 83 ?

and how much amp power i should use for the Klipsch rp250s and rp140sa?

i can get an almost perfect condition used emotiva upa 7 cheap and wonder if that is enough power for those 6 speakers ?

(my adcom 7705 is not in use atm because it needs to be fixed so atm im using only the onkyo for power and its not even close

to handling my speakers so im playing at low volume, which i hate!)  do you have any good recommendations for a good amp if the 

emotiva upa 7 isnt good enough for the speakers? 

 

Thanks in advance for any help i can get, Thomas

Mac78,

 

Welcome to the forum.

 

I would use the 7705 to drive the 83's, 64II, and RP-250S's and use the RZ810 to drive the RP-140SA'a.  At minumum, let the Adcom drive your L-C-R.  Your Onkyo's auto EQ will volume match and set proper delays.  No need to buy another amp if Adcom is operating properly.

Hi and thanks for replie. i forgot to say that i got 7.1.2 setup with 4* Klipsch rp250s, will it be enough power from my onkyo alone to power those? i play music in all channel stereo so i dont want to have to low power on any speakers

I believe it will be plenty of power.
