Watched this (thanks!) and explored the uploader's web site, where I found (among other interesting things) an article with this quote:
"Myth: Digital audio sounds worse than analog, and the lack of digital's fidelity is revealed as a sterile and harsh sound that lacks warmth, depth, imaging, clarity, and any number of other vague and elusive descriptions.
Fact: Analog tape compresses dynamics and adds distortion, which can be a pleasing effect for many people (including me). But for pure faithfulness to the original signal, modern pro-quality digital wins hands down every time. It is true that when digital audio is recorded at too low a level, the result can sound grainy. This distortion is in addition to the hiss that an analog recording also has, and it is caused by using an insufficient number of bits. That is, recording at too low a level on a 16-bit system is similar to recording at a normal level on an 8-bit system.
Vintage analog synthesizers may sound "warmer" than current digital models, but only because of the distortion inherent in their design. That wonderful fatness is the result of pushing the analog VCF and VCA circuits to their limits, in an effort to obtain a usable signal to noise ratio. But there is no reason a modern sampling synth cannot reproduce, if not generate, those same sounds exactly if given a proper source signal.
Myth: Gold-plated connectors sound better than connectors made with tin or nickel.
Fact: Gold does not tarnish, and tarnished connectors can cause problems, but there is nothing inherent in gold that makes it sound better than a clean connection using standard materials. Further, it is possible for connections using dissimilar metals to oxidize and deteriorate more quickly than if the same metal were used. So, mating a gold plug with a non-gold jack could theoretically make things even worse! Moreover, connectors plated with gold often use a very thin coating because of gold's high cost, and that plating can wear off with repeated plugging and unplugging. Therefore, while it would be unfair and untrue to say that gold connectors are a bad thing, unless both connectors are gold they are at best a waste of money and at worst a potential for eventual trouble."
