power consumption

[Polkfan]

Well, yes, Polkfan explained very well why the voltage of "mass market" receivers is overstated; Polkfan informed with logic and understanding what's really happening in this specs war; i understood Polkfan very well and now i know why my Yamaha receiver is capable of delivering only 55 watts per channel all channels driven.
But you, Mr. Av_Phile with your rudeness, the only thing that you provoke is a sterile discussion with no end. All your affirmations were not sustained, typical in people of your kind (as you named one person in this forum). We're trying to take away this mystical-mist to the audio experience; we're trying to tear down this subjetive component that "audiophiles" exploit very well against ignorant people; the only thing that "audiophiles" do is perpetrate the ignominy. Please, be sure that the next statements you invoke are at least minimally sustained (just like Mr. Polkfan does).

While I would love to take full credit for the information in my post at the beginning of this thread, it is important to note that I merely quoted the AH website. But thanks for the kind comments.

toquemon,

I think we are all getting infected by dissent, redundant bias and prejudice of a certain person and sadly this is bringing out the worse in us, I have probably been the worse effected, so I will back off from this thread and I suggest you do so too to preserve your sanity which seems to be totally lacking in this individual's case. However, I will continue to retort and elucidate any misinformation and snobbery put out by this individual in future threads, thats a promise.

I thought we are biased towards the facts and the truths, in this case in audio matter but I am sure that many here carry it into other aspects in life as well?
Some would never see that even if it hit them squarely head on. Then they may have to admit being WRONG!

power

I have read many of the 'truth in advertising' posts about amplifier power. This is a nutty arguement. My stereo gear is 200wpcX2, both driven 20-20k @8ohms. I have never listened to anything even approaching that requirement and I listen LOUD with inefficient speakers. If I had my 'dream specs' for an amp it would be::
1. Max RMS power, 1 channel driven @% @8ohms 20-20k.
2. Max RMS power, ALL channels driven, under the same conditions as above. even 5ch AV stuff.
3. Repeat @4ohms.
This will characterize the power supply as loose or tight......I had a NAD power amp years ago with about a 3db dynamic range....that is the short term power of DOUBLE the RMS rating.
Sony made some stuff with switching power supplies that had NO dynamic headroom and higher RMS ratings than the NAD.....you choose.
I am having the 5X200wpc Rotel delivered for my new HT. I don't care if it is really only 150 or so. The 4ohm rating (myspeakers are 5 ohm) is more important to me....and it is 330 wpc. This tells me it has a nice robust power supply.
At this point, what I FEED IT is more important. Go to the local Best or Good Guys and check out the Monster display....watch the incoming voltage SAG as you turn it up. This is what really hurts. Good gear by (fill in) being fed junky power....and at a low voltage. Repeat the calculations from other posts for 110v....or even 105, than add in substantial powerline JUNK and you figure it out!

Still irrelevant as that need to drive all channels to full power at the exact same time is just not on any recordings.
Is the HK delivers 85 RMS watts to all channels at the same time? We went through this before. I don't think it will; maybe 50? But it is still irrelevant. What will it do into two channels or one where the need is most likely the case?

I agree, take a Sony STR-DA4ES, S&V did not test its all channel driven power output because Sony told them the unit is not designed to output 110W with all 7 channel driven, but it was tested to output significantly higher than the 110W PC with two channel (Stereo) driven. Its output rating into 4 ohm was even (much) higher.

HT magazine (August issue) just reviewed and lab tested several simiarly priced AVRs including the HKAVR630 and the Denon AVR3805. While the 630's 7 channel rating was "as advertised", its two channel numbers were much lower than that of the Denon AVR3805. The thing is, for roughly the same price (3805 vs 630), the 3805 delivers more real watts, even though the 630 delivers the all channel driven power as advertised. In other words, people who bought the 3805 would have got less power should they go with the "conservatively" rated AVR630.

I really think those "conservatively" rated models tend to spend their money on beefing up their power supplies while others such as Sony, Yamaha and Denon focus more on the amplifiers, hence their generally much stronger 1, 2 channel numbers but lower "all channel driven" numbers.
