Power hungry speakers

[Guest]

<font color='#000000'>Zumbo...that link does not bring up the review so when you get that first page, select manufacture as Marantz, then hit the search botton...When you get the Marantz page click on model 5400...this is where the Yammy, Denon, Onkyo, Pioneer and Marantz reviews will be.</font>

<font color='#000000'>wow, i'm shocked my question sparked such a heated discussion! &nbsp;I am inclined to agree with those of you arguing the max power is limited by the power taken from the wall. &nbsp;however, this amp will only be used in a 2-channel setup so zumbo, you're suggestion is well taken also. &nbsp;however, i have to shy away from yamaha's slightly bright sound (or high-end &quot;sparkle&quot because my speakers really emphasize it. &nbsp;that's why i narrowed down to the darker, warmer sound of the h/k and the very flat and musical sound of the marantz.

still no one has said...any suggestions as to which will power my speakers better (ignoring sound characteristics)? &nbsp;unfortunately i do not think i'll be able to listen to the receivers back to back so power may be hard to compare.</font>

<font color='#000000'>The YPOA can be set to not emphasize the high-end.

If you can only make the power that comes from the wall outlet, then how is any other model going to make more power. That is by far the most ignorant statement I have ever read on this site!

Start a thread that says &quot;best receiver for $500&quot; and see what you get. The RX-V1400 is by far the winner.
TRY IT AND SEE!</font>

<font color='#000000'>Well, both of those recievers will be ok with those speaker.

do have a clue as to what power in regards to electricity is?</font>

 

[zumbo]

<font color='#000000'>I am not claiming to be an expert. This thread was for opinions on a good receiver choice for around $500. That is what I gave. Now, as for the other ignorance, there is no way you can make me believe that power is limited to what is supplied from the wall. That would make all purchases above the bottom-of-the-line a waste of money.</font>

 

[zumbo]

<font color='#000000'>Electricity is converted into heat. This is the wasted power. Electricity comes into the house and also leaves the house. The wasted power(heat) that is used is what you are billed for. So, when you have a receiver making more power and heat, you will be using more power from the wall.</font>

<font color='#000000'>Between the Marantz and the H/K I would say it is kind of a toss up. They are both good receivers. I personally like the H/K, or an NAD. Either way you cannot go wrong.</font>

<font color='#000000'>Well if I may add my 2 cents, the power from the wall is 240. Its the amplifier &nbsp;sction within the reciever that delivers high current power for continuously clean and stable wattage into each amp channel. &nbsp;It is the power supply, large filter capacitor and heat sink that ensure that the most demanding speakers are driven effortlessly. This is what we call High fidelity. And thats my 2 cents worth.

<font color='#000000'>annunaki,
Where can you get an NAD or H/K that compares to the Yahama RX-V1400 for $500?</font>

 

[goodman]

<font color='#000000'>Zumbo, look at it this way: An amplifier does not amplify the wattage, it amplifies the signal that is fed into it. &nbsp;These guys are right -- you cannot get more watts out of an amp than you put into it.</font>

 

[annunaki]

<font color='#000000'>Zumbo, what is so hard to understand. On a 120 volt socket with 20 amp service there is a total of 2400 watts available. (V x A)=W &nbsp;V being voltage, A being amperage, W meaning watts. A receiver with a class A/B amplifier having 55% efficency will waste 45% of the 2400 watts in heat, leaving 1320 watts of actual amplifier output power. Assuming of course the power supply is large enough. &nbsp;A receiver is limited in power output by its power supply. If a receiver or amplifier's power supply were large enough to make full use of all the power and then some, then of course you would be limited by the wall socket. Believe me there are amplifiers big enough to do this. I can assure you that they are not the amplifiers found in receivers.

As for &quot;ignorance&quot;, you are the one being ignorant. What you were stating before was like spitting in the face of the laws of physics. You need to get the power from somewhere, and it come from the wall.</font>

the max apparent power from a 15amp circuit in the USA would be 1800 watts (15 x 120) this would be available to any equipment that is plugged into this outlet. the maximum power that your 1400 will draw is 500 watts as stated in your owners manual. any higher and the internal protection circuit will trip shutting the unit down. a few years ago its was a fusible link in the transformer that would fry and the unit would have to go to service and the input transformer replaced. thankfully this is no longer the case. it was such a problem that one of the faqs on the yamaha website was , why did my transformer in my receiver fry again?</font>

 

[zumbo]

<font color='#000000'>Preaching on about ignorance. Why are we debating over an A/V receiver when the use will be 2-channel. I would spend my $500 on a 2-channel amp.

But again, if we are limited to the 120v plug in, why are there larger amps available? What am I missing here?</font>

 

[annunaki]

<font color='#000000'>How about an AVR-325 from last year. Rated at 55 watts x 7 all channels driven simultaneously. Actual output: 90.4 watts rms x2, 73.8 watts x 7 rms (both measurements taken at 8 ohms) at .1% distortion, all channels driven simultaneously. DD-EX, DTS-ES, DPL-II, DTS NEO 6, Logic-7, RS-232 upgradeable, multi-room/multisource, learning remote, auto set up, bass management, 8 channel audio in/out, component video switching, ect. For around $430 on ebay.

What does the 1400 have that the H/K doesn't besides less output power in surround mode, and a bunch of useless DSP?</font>

 

[zumbo]

<font color='#000000'>Aarond. With your statement in mind, the 2400 and the 1400 both draw 500 watts. So it is my assumption that the 2400 just cost more for the hell of it! Glad I made the right choice!</font>

 

[annunaki]

<font color='#000000'>We are not limited in amperage however. We can go up to around 210-220 amperes of sevice on a 120 volt line. That is 25,200-26,400 watts. What limitation? I don't know why we are talking A/V receivers. You are the one who suggested the Yahmaha 1400. I too would just get an integrated amp or separate amplifier.

As for the 2400 and the 1400, it makes you wonder what you are really paying for. DSP? DACs? Dang those marketing guys!!

</font>

 

[zumbo]

<font color='#000000'>The 2-channel use came out later along with the $500 limit.

The 2400 &amp; 1400 have the same options! 2400 rated at more power.</font>

i finally agree with zumbo on something. if this is for stereo only you could do alot better with a stereo amp. if you like the sound of hk have you looked at the hk3475 &nbsp;2x110</font>

 

[zumbo]

<font color='#000000'>I would like to make a final recommendation based on the fact that he needs a 2-channel source for $500. Just add this to your current receiver.

NAD C270 from yawaonline for $479.99. Comes with full two year warranty.(2 x 120w)

Or, if you do not have a current receiver, you can get the C370 intergrated amp for the same price. You will have to add a tuner to pick-up radio stations.(2 x 120w)

I am done with this one. It was fun and informative!
