Subject: UPA-7 question on headroom;
I Pre-ordered a UPA-7 I’m using a TX-NR 5008 Onkyo AVR(it’s brand new) I’m going to be running a 9.2 system of Kilpsch Hertiage speakers modded with better drivers (Crites) 4 cornwalls & 5 Crites CS1.5’s ( Cs-1.5 is a modded Hersey but a 2 way) the 5008 sounds great in 7.2 over what I had before (TX-NR807 in 7.2) but I get just alittle less volume but the 5008 is clearer in sound running 7 speakers . haven’t yet put the extra 2 CS-1.5 on yet soo I do have a good A/B comparison between the two AVR’s . I do know that most AVR’s are dropped down in per channel wattage the more speakers on the AVR I’ve read the 5008 drops to 75 watts @ 7 channels driven
5008 is rated @ 145 watts @ 2 channel
807 is rated @ 130 watts @ 2 channel
what I’m looking for is more headroom in the soundstage(clarity,detail,depth) I got a little better of each of those with new 5008 but I want to take it further ;the reason I feel I need the UPA-7
looking @ running 7 channels off the UPA-7 & 2 channels off the 5008 when I go 9 channels
now does going with this set-up gonna add the headroom I need /looking for ?
the Audyseey has set to crossovers on the Cornwalls @ 40 soo they are sucking some watts there . sounds great having the Cornnies having a low direct impact .
the subs are self powered SVS PC12-NSD’s
thanx Michael

Hello Michael that is correct most AVR’s as you load them up with more channels their output drops appreciably. Our power amplifiers stave off that loss due their high current swing and high voltage Swing. Even the 5008 cannot compare with even my smallest 2 channel amplifier in current/voltage swing. Our UPA-7 could be just the right solution to give your 5008 a fighting chance to deliver its best.
