sq amps?

ill add my two cents when i get back from school but its wrong for ppl to say you wont hear the difference.. when ppl say a watt is a watt. . . thats BS because things have been taken out of the equation......... i'll explain later....

 
No one around my area carries Boss so I had to buy US //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif I do have a Rockford Fosgate Power 851X though. Actually I had it on my current system but I wanted to go active so I just used my US Amps. We were a dealer at the time plus I thought it was pretty cool with the viewing window on the back.

 
All things equal, you won't be able to tell a Rockford Power series sound from a Zapco from an Audison from any other amp you buy.
That I would have to presently disagree with.

I haven't seen the article myself, but on another forum it was mentioned that CA&E recently tested one of the RF power series amplifiers to have a 4db boost in two different frequency ranges......that would be audible.

It also could be corrected with an EQ, however, resulting in an inaudible difference after correction (assuming power, gain, noise & distortion were also inaudibly different).

ya, a class A circuitry amplifier, they're used because of there low noise properties. I have seen some have a total harmonic distortion of around .0008% big difference from the usual .05 of a class A/B and up to 1.% of a class D.
All of which are below the threshold of audibility with music.

So it's a moot point and not a "big difference".

Much as many people can tell when a passive crossover in a component set is using higher quality caps and air cored inductors,
Many people heard an increase in dynamics and image separation after marking on their CD's with a green marker, aswell //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif

Have any scientifically valid studies showing that two caps, one "low quality" one "high quality", of identical values alter the response differently ?

better parts quality inside an amp will also be detectable.
Only if it audibly affects frequency response, distortion, power, noise or gain.

Regardless of components used, if all of the above are within inaudible tolerance differences will not be audible.

its wrong for ppl to say you wont hear the difference..
Correct.

There will be a difference in sound if there is a audible difference in frequency response, power, gain, noise or distortion.

when ppl say a watt is a watt. . . thats BS because things have been taken out of the equation.........
Correct aswell.

One watt of a square wave is different from one watt of a sine wave.

 
Wow, first off, a watt is a watt. just like horsepower is horsepower. If you buy a amp and plan on using its on board processors, than you can definately hear the difference between amps. However if you buy seperate external processors(eq,crossover), than the amp you buy will not make much difference. Now obviously a cheap amp rated at 1000 peak will not be as loud as a quality amp rated at 1000 rms. But a watt is a watt, the difference is in the quality of the onboard processors.//content.invisioncic.com/y282845/emoticons/graduate.gif.d982460be9f153bb54e5d4cb744f6ae8.gif

So a 1w sine wave, 1w square wave and 1w sawtooth wave are all identical ?

But a watt is a watt, the difference is in the quality of the onboard processors
So someone wouldn't be able to hear the difference between a RF Power series w/ a 4db ripple in response and an amplifier with flat response ?

Someone can't hear the difference between a full range amplifier with +/- 1db 20-20khz frequency response and a bandwidth-limited mono amplifier that begins to rolloff it's response @ 350hz ?

I'm not even going to respond to that. Wow, what was i thinking

To the OP, if you had a kicker sx900.4 and a kicker zx850.4 to run your components, the sx amp has a built in dsp,built in eq, time alignment etc. Thats my point, with the zx amp you'll need external processors to do that, whether it be head unit or whatever.

 
If that was your point.......you did a poor job of exemplifying it originally.......
yeah, because what i said earlier about the difference in amps being the onboard processors was too difficult for the average person to understannd, unlike what you wrote.//content.invisioncic.com/y282845/emoticons/rolleyes.gif.c1fef805e9d1464d377451cd5bc18bfb.gif

 
A real deidicated Sound Quality amplifier wont have any on board processing or crossover. It will be built with superior 1% tolerance components and on mil-spec PCB's.

If you think all watts are created equal you are either deaf or just plain stupid.

I have that issue, I also have that amp exact amp paired up with my subwoofer.

The 4db gain that was mentioned occured when the lowpass filter was engaged. The article also shows a few graphs, one of them being the frequency response curve. The graphs pictured are small and kind of blurred, and so the numbers are not that easy to see. There are two different lines shown within the graph. From what I can see, the frequency response curves seems to show 1.25db - 1.5db increase in the bass region, and 1db - 1.25 db increase in the upper ranges.

This may be the closest answer to the truth. A good amp should add nothing and to achieve this, they try to use the best parts available. Is a watt a watt? I would say yes. But how that watt sounds after running through a bunch of parts will determine the end sound. If you had a tolerance of 5%, that is audible. Now keeping tight specs will help to get you closer to the engineers reference.

I'm not sure if any follows along with home audio, but look at Wilson Audio. Great stuff and they tolerances that they work with are insanely tight.

In the end I think a "sq" amp is high quality parts with very tight tolerances. The SPL etc are more of a "don't break" but really ok if they don't hit the exact spec that was pre-determined.

do the test and get an easy $10 000. It's really easy.

Also the true sq amps aren't cheap either. Yes they don't have crossovers or eq's but that comes at a p rice

On a serious note....what amps do you know of that use precision components?
