Are all Watts the Same ??? :) - Blu-ray Forum

kevinokev · 01-12-2009, 08:46 PM

I am in the market for a new receiver and was wondering if different brands (Onkyo, Denon, Pioneer) vary from each other watt for watt. Is my 100 watt Kenwood receiver the same as 100 watts being put out by an Onkyo or Denon ??

Just curious as I'd like to have the same amount of power going to my speakers that I currently have...

Your thoughts???

Well why not get something that can give you more power if your upgrading your AVR?

Second this question, as my Kenwood Reciever is a piece of.......

NO.

You need to look at the watts at the same percentage THD (total hermonic distortion). Also you need to look at the ohms resistance of your current speakers and make sure that the new receiver is going to match up or you will have less sound output or worse yet you will fry your new receiver.

Can you clairfy further please ?

Driver_King · 01-13-2009, 02:09 AM

Here's an extremely complicated technical explanation for you.

That is my cousin's website.

kevinokev · 01-13-2009, 01:06 PM

Would 100 watts of Kenwood power be equal to (of the same quality) of 100 watts of Denon power?

ie - 100 watts of Fosgate power is equal to 400 watts of California Profile power. As the Fosgate is a higher quality amplifier.

I would like to get a new receiver with the same amount of power that I currently have, but I can only seem to afford a Denon amp that outputs 90 watts per channel.

I am not an audio expert by any means. I just know what my ears enjoy.I have had a nice car stereo and now I am in the prosess building my home audio.All this talk about watts.Lets talk about where the watts will end up.I know with my car stereo the high frequency speakers did not use anywhere near the power of my subwoofer, and let me tell you ,the sub is what really made that stereo. My head unit drove the the high and mid range speakers and then I had a large amp just for the sub.For the record I am big Metallica fan and that music is pretty heavy on the bass,I like it as close to concert volume sometimes.My idea of a good powerfull home stereo would be a quality reciever{i have been looking at the pioneer SC-05 or the SC-07}I will use that to drive my loud speakers, probably polks of some kind. then i am going to throw a large chunk of my money at a really good powered subwoofer and put it on its own circuit breaker.I think that will fix me up very well without having to resort to buying amps for my reciever.You might think about something like this. Also I want to use this system with the flat screen and bluray I just bought. Thanks Neil

here's a review of NAD receivers

..More alarming, the T743 supplies only 50 watts of power to each of those five channels -- two front speakers, a center-channel speaker and two surround speakers -- where some of the least-expensive receivers routinely claim to hit 100 watts a channel.

...But when NAD calls this a 50-watt receiver, it's using the industry's most stringent standards. According to the company's "full disclosure" ratings, the T743 delivers an honest 50 watts into each channel driven simultaneously at low distortion (under 0.1 percent) across the full bandwidth of human hearing. Other receivers are measured into only one or two channels, with much higher distortion and at a limited bandwidth.

...Greg Stidsen, NAD's director of product development, said the company recently measured a competitor's $1,200 receiver rated at 105 watts into six channels. With the same standards used to measure the T743, says Stidsen, this 105-watt receiver "could only output a rather pathetic 12 watts per channel." Yet this same receiver, says Stidsen, can be advertised as having 630 watts total power (six channels times 105 watts).

i love my NAD

Yeah, a watt is a watt but the quality of that what is what makes it different.

Here is your answer: No.

BluLobsta · 01-13-2009, 06:20 PM

Yes, but I prefer to multiply the square of the current by the impedance of the speakers

Just kidding...

But all of that is beyond the scope of his question.

That's why I linked him to my cousin's website. He explains all that.

Driver_King · 01-13-2009, 06:43 PM

I'd prefer to have 15 quality watts over 100 garbage watts.

I searched my garbage today and couldn't find any watts.

Someone stressed me with a lot of watt-ifs today! Does that count?
