[QUOTE="squeak9798, post: 3218150, member: 555320"] 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......[I]that[/I] would be audible. It also [I]could[/I] be corrected with an EQ, however, resulting in an inaudible difference after correction (assuming power, gain, noise & distortion were also inaudibly different). All of which are below the threshold of audibility with music. So it's a moot point and [I]not[/I] a "big difference". Many people heard an increase in dynamics and image separation after marking on their CD's with a green marker, aswell [IMG]//content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif[/IMG] Have any scientifically valid studies showing that two caps, one "low quality" one "high quality", of identical values alter the response differently ? [B]Only[/B] 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. Correct. There will be a difference in sound if there is a audible difference in frequency response, power, gain, noise or distortion. Correct aswell. One watt of a square wave is different from one watt of a sine wave. [/QUOTE]
