They typically get closer to their rated wattage than other receivers.
I just know that if going on power alone and nothing else, going from a 110 watt receiver to 140 watt isn't that big of a difference. If going up to a 140 watt receiver is a big jump in price they will typically get closer to actual wattage also. A standard 100 watt receiver may only get 30 watts per channel with all driven. Some of them will only achieve that for a few milliseconds. The more expensive receivers usually do a better job at it.
I remember something I read once that seems to hold true. Buy by weight. With a bigger transformer comes more power. An all digital amp won't weigh nearly as much so those wouldn't count in that.
I have to disagree.
It's those few milliseconds that make a big difference . & most modern AVR's are placing so many features in the units that the amp sections are taken a big hit as well as the capacitors are not as big like in the past as well . Plus then add 5,7,9 channels driven really makes the AVR run at near what it can do & they loose steam , fail at getting the dynamics @ key moments (that is a huge issue in the modern sound tracks on movies) . if go back & look at older AVR's you will see they weight alot more than the current Flagship AVR's on the market today.
I have a TX-NR5008 Onkyo , a Flagship AVR ,
the newer flagship AVR's are lacking in good clean power when pushing 7 to 9 channels .
My 5008 is rated @ 145 watts per channel but when bench tested by a testing group it was only pushing less than 70 watts per channel on 5 channels driven , now to be fair the 5008 is the best AVR I've ever owned & sounds Great pushing 5.1 but it quickly looses steam with any more speakers added or in a very dynamic Action Movie .Since I have added power amps to system detail,headroom,noise floor,dynamics all have take a huge expansion of my soundstage
a separate power amps running my 5008 as Pre/pro is the best of both worlds,1st class AVR & enuff power to add real punch to the soundstage
So I added a UPA-7 by Emotiva to push my Heights,wides surrounds ,center & left the mains on the 5008 & I was in bliss it sounded great . But found it odd that my mains were some what lacking in dynamics ( they were being pushed by my 5008 so they were getting 145 watts a channel , still some thing was wrong . Emo has the UPA-2 on sale right now so I added that to the mix running the mains off the UPA-2
It was eye opening addition as now my main sing along with the rest of the channels & I now have a massive dynamic soundstage , no real change in volume levels But WoW the Dynamic response is astounding VS just what I had when the 5008 was running with it's amps
BTW the UPA-7 was 80 LBS shipped & the UPA-2 was 50LBS shipped & both units have HUGE Toroidal transformers as powersupplies .
my best advise these days to anyone buying a new system, is get the best power amps you can ( Amps never really go bad & they never get obsolete..soo once you buy a great power amp it's good for life ) Then get a Pre/Pro with features you want (this is the unit that over time will become obsolete)
another option is use your current AVR as a pre/pro & add power amps ..later down the road when the AVR is obsolete you already have the amps & just add a pre/pro
I see that OutLaw has it's 7 channel Amp on sale right now & that's a great unit & great price .http://www.outlawaudio.com/products/7125.htmlhttps://www.outlawaudio.com/mofcart/electronics.html
