This is a pretty good video by Lachlan.

Yup. Can't say I'm getting a LightSpeed anytime soon. I would look into some of LH more reasonably priced (and mature) gadgets.

BTW, Cat 7 can do 10Gbps over >100m. Here a $5 10ft chunck:

You may ask yourself why so cheap? Well. Was it made in a vacuum chamber? No. Was is cold welded? No. Does it have silver? Seems mostly copper so proly not.

What does it have to do with USB cable? Nothing, but it passes 10 Gbps.

Cat 7...man.
First: "Category 7 is not recognized by the TIA/EIA."

Second: those Newegg cables might not pass Cat 5e. If you're buying it from a consumer market retailer than I would genuinely doubt it's anywhere near Cat 7.

Curious to know what folks think about this video. I don't feel like I have good enough theoretical understanding of this to say one way or another. I have read this argument before several times, as well as counter arguments.

He did not address recording, production and mastering in the video. Thing is, his presentation is good enough to make a partially visual learner like me dig a bit deeper.

I used to compare 16 bit and 24 bit recordings. I used to have vinyl records. Between the three I prefer the rich vinyl sound and while 24 bits can give you more subtle details I am still content with 16 bits audio. For different situations different solutions apply if you ask me.

I generally agree with DF. Saying nothing about Lachlan's ultimate conclusion (and justification for the same) this provides a very accessible understanding of what bit depth actually means. Years back, I had to read forever to try and understand it, and usually articles included all kinds of shitty metaphors (fucking cars). Lachlan includes none, actually explains bits in this context, and uses actual hypothetical examples (jackhammer, NASA launch). I see the value of having higher bit tracks, but I can also see how for most people, especially those watching Lachlan - who admittedly caters to lower cost, more accessible, more portable gear - would realize no benefit from 24 bit.

Yeah, that is the first one lachlan cites to as well. Its very good, but gah, so many words.
