It doesn't become relevant until it is used. Of course if you need it for peaks it makes some difference. But by definition if its unused it csnnot make a difference at least in the four dimensions of the universe we experience. Fwiw,at my usual listening levels (-10 to -20 dB from reference) with a sub average levels likely require a tenth of a watt at most with max peaks maybe needing 10 watts for a tenth of a second or so every now and then.

OK sea lawyer. But it has no effect on sound when it is not being used. Everybody needs some overhead over average power dissipation. But audiophiles have the impression that 20 watts from a 200 watt amplifier sounds different from 20 watts from a 50 watt amplifier and that simply isn't true..

Amps provide watts & current. These create an amp's sonic signature.

Some argue that all amps sound the same - and they are right.

Others find that amps have a distinct sound that varies by brand and model. They are right also.

We all hear differently, and percieve sound differently.

That's why there are a variety of audio component choices.

I see a XLR preamp in your future. The difference continues to be huge at this level.

Correct me if I'm wrong but I thought most movie soundtracks (obviously not all of them) actually had more dynamic content than music did. Especially modern music that tends to be dynamically compressed.

It's easy to make movie sound good, it's very hard to make music sound good. Music is far more demanding/complex input.

I think we're talking about different things. My post was just in the context of which content generally has a greater dynamic range. Like I mentioned, I am under the impression that most movie soundtracks have a greater dynamic range than most music and especially most modern music, which is often highly compressed.

That said, high levels of compression can result in music being more demanding on an amp if the average playback level is higher.

"Sounding good" overall is much more dependent on speaker and room than amp. So long as that amp is transparent (most are) and supplies sufficient wattage for the intended listening level.

The thread has commented on my statement of" my error in thinking" the Crown XLS-1500 325 watt per channel amp would be better than the Emotiva or parasound 100 watt per channel Amps. I read a review here & bought the amp & enjoyed it for a year or so, then sold it So!
IMHO the sound quality; the ability to make the CD's that I own sound good or better, as in bass mid range treble & moreImportantly "Dynamic Range" presence & Sound stage. The Emotiva did better & the Parasound Hca800ll did even little better, & the Music hall mambo blew them both away by a 10-15% amount. I hope this helps everyone that commented? For me I am blown away by this Integrated Amp that is so so sooo much better IMHO. 50 Wpc class "A" ONLY.

I think that small amps like the Cyrus 50Wpcnl can & do sound better than some 2-300watt Amps.
I also think that the dynamic range of some music & movies requires quite a bit more "Current" & watts
than the 20 you reference. But when using Efficient speakers like the Pinnacle AC-850 you could be spot on, as I've heard them with a 30 wpc tube amp sound amazing!
all things being equal a 200 watt per channel amp should have larger power supply,& capacitors & other good stuff standard that would make it more "likely" but not definitely sound better. Higher quality products have great parts.

These are the same two amps I am considering to drive my Triad Gold LCRs, which are 4 ohm, 3.2 ohm min. I need 2 amps for the 3 channels. The 1500 is $209 and the GX3 is $299. Pricewise, a fairer comparison might be the XLS2000 at $249. For simplicity of connecting to my Denon 4311ci, and lower noise floor, do you have a preference between the Crown and the QSC?

I have seen an older Crown CTi 4200 4 channel amp used for less money, but am thinking with the prices of these new amps, buying new would be smarter, and still less than an XPA-3.

Thank you.

No, sorry, perhaps you're too nice to really understand the issue. If we perceive sound differently, then you would be able to prove that perception. The double blind studies on the topic show that people can't tell the difference between amplifiers below clipping in volume equalized tests.

That's what the data shows. Your opinion above, while highly political and crafted so that nobody feels alienated, is ignorant to the data on the topic.

Well you can reay on data or your ears.

Remember that once upon a time the available data led to the conclusion that the earth was flat.

Please don't reply. No sense in talking to anyone you think isn't up to your level.

^^^ And vice-versa...

@Geordon : Regarding the Crown and QSC amplifiers, I have not heard them side-by-side but spec-wise they are pretty comparable. The Crown has slightly lower sensitivity but a bit better SNR. The Crown states it is rated to 2 ohms while the QSC states 4 ohms, and the Crown can be bridged (not sure about the QSC). In practice there's probably not a real-world difference.

If you can rely on your ears, then in a properly constructed double blind tests, you'd reliably be able to tell the difference between volume equalized amplification below clipping. People who do this, can't. They rely on their ears to tell them one thing, but when you take out subjectivity its shown to be false.

Your argument is poorly constructed. Aristotle used actual evidence to put forward his idea that the earth was round. Exactly the opposite of what you're saying.

Feel free to find ANY data that shows that the difference in amplification is anything but subjectivity.

A good read for you. Not too technical either.
