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.
