"Is the power adequate to drive my Energy RC-30's and sound good without adding an additional amplifier? I want it to sound nice and tight/full at low levels and moderate levels"
Denon 2807 - 110 wpc, 30 lbs
Pioneer Elite VSX-82... - 130 wpc, 35 lbs
Both these amplifiers have plenty of power and should drive any good surround speaker system up to $3500 in cost. Assuming you will be using a good center channel but not big floorstanders for the front (L+R) speakers.
I would be partial to the Pioneer Elite because its larger and better power supply will allow the unit to do what you want (tight, quality dynamics at reasonable listening levels) better.
However, a friend of mine has an older 80 wpc Denon and it is a very good unit. I just perceive the Pioneer Elite to be marginally better. Either unit would be better, in my opinion, than many of the other "reasonably priced" brands.
One thing to consider, at your price point I'd be taking a hard look at the Outlaw Audio Model 1070 A/V receiver
. And don't let the 65wpc power rating dissuade you unless you are going to use large power sucking speakers - with the normal $2000 for the 5.1 system speaker setup (like Definitive Technology Pro Cinema 1000 system) I'd bet the Outlaw unit would smoke both the Pioneer Elite and the Denon units. BUT, if you select an Outlaw unit make sure it comes with HDMI switching as they have been slower to incorporate it...
Ooooooooooh, wait! One of you do have floorstanders!
For one of you, I'd talk to someone who has the Outlaw receiver and the Energy speakers before jumping on the Outlaw wagon train - the Energy floorstanders would probably work fine with the Outlaw receiver, but they might also benefit from both the power supply and the extra wpc of the Pioneer Elite Receiver. I'd suggest the Denon would be not the better choice with floorstanders, just because of its lesser power supply.
[Power supply capacity/adequacy can be approximated
by comparing the weights of receivers, as it contributes to the majority of a component's weight. Notice, the Outlaw receiver weights 40 lbs
at (conservatively rated, all channels driven at the same time
) 65 wpc. IF
indeed it would smoke the other two units (driving medium sized speakers) part of the reason would be because of its superior power supply.]
I guess, one point I'd like to make (say again, differently?) is: for quality, not quantity, power supply is more important than wpc. In the not that rare case of when (in higher end equipment, even when played to quite loud, but not ear splitting levels) a 80 wpc receiver smokes a 110 wpc receiver it almost certainly due to one having a good power supply and the other having a supreme power supply.
A third way to say it ( I know:
): I'd suggest, until the Outlaw unit "peters out" becuase it has done all it can with whatever power (wpc) it has available, it would sound better than either of the other two units."much more important to me than being able to piss off the people across the street."
that was funny. Probably a good goal to have (musically, as well as socially) too.
