[1] Because he doesn't answer with real technical information.
[2] I believe A+ and EQ are separated features. But it could be some sort of equalization with A+. [3] The engineer told me A+ will fill the "original data" into sample to make the block closer to perfect sine wave. [4] I think his explanation is similar to dithering where you fill noise to improve sine wave form.
1. Yes he does! It's just incomplete, sometimes vague and often incorrect.
2. Have you read the linked documentation in the article you quoted?
3. Exactly my point! Accepting the marketing BS of what you were "told" demonstrates extreme gullibility and a complete ignorance of digital audio. In digital audio, the samples already contain ALL the "original data" required to make/reconstruct a perfect sine wave. This is basic digital audio 101! As there is therefore nothing to "fill", A+ must, by definition, BE DOING NOTHING! To support this; if A+ were doing something, the only thing it can be doing is distorting that sine wave but they explicitly state this is not occurring!: "In 1985, audio designer Mark Levinson created the legendary Cello Audio Palette, the world’s first sonically transparent tone control system. The Cello Audio Palette is today the most expensive and rare audio component, prized for its ability to fine tune the sound with no distortion or noise. Master Class offers the same capability in the digital domain..." He also states that when switching A+ on and off; "The change is very subtle and many people will not hear it immediately, but the listening experience is not the same." Which is also absolutely consistent with what one would expect of any marketable feature (IE. A+) which actually does nothing at all!
4. It's not even vaguely similar to dithering, he effectively explains the software as just an EQ (or more precisely, as an EQ plus a placebo function). He explains ONLY what it's EQ capabilities are and even advises how to set it as an EQ. Although completely unrelated, dithering is NOT filling in with "noise to improve the sine wave form"! How could filling with noise improve a sine wave anyway?
