Who Posted This? "60% of Hipsters will tell you, you cannot comprehend 80%..."

Someone posted a link or an image about this, recently, I think, and I've been enjoying this article. Not done yet, as it's long and is going to take another read or two to digest, but wanted post back saying it's interesting. Can't remember how I got to it, though, dehr.

it is a good read!

Yeah, I thought so, too. It was cool hearing the perspectives of different industry people on analog vs digilog.

I may be missing something -- they show an impedance plot for a real loudspeaker load:



... but then they show the THD+N as a function of power (measured as dBu which, if I am reading correctly, is a reference voltage of 0.775VAC RMS) of their amplifier... driving a four ohm load. Presumably a pure resistive load; the loudspeaker in the plot above isn't a "four ohm load" -- even if it has a nominal impedance of four ohms.



I mean, the amp may drive the speakers perfectly well to any reasonable (and perhaps even unreasonable) SPLs in a real-world room... and it may sound great, or not, doing so... but the two graphs are essentially unrelated from my perspective.

Drive a load that looks like that loudspeaker (a mixture of fixed DC resistance, and frequency-dependent capacitive and inductive reactance) and show me that curve (i.e., THD+N as a function of power) for a number of frequencies: 20 Hz, 45 Hz (those two resonance peaks in the LF of the loudspeaker), 200 Hz, 1kHz, 10 kHz and 20 kHz and let's see how the THD+N plots for those conditions would look.

Unfortunately still won't tell you much about how the pair sounds.

Sorry to be the grumpy old man -- now, excuse me while I go chase some punk kids offa the lawn

Can you tell I posted that to the wrong thread
Sorry!

Lolol
I thought, Dag, I haven't gotten that far yet; this article is more technical than I first thought...

had to look this one up - Irwin Corey?

Motor - was that you who originally posted that image/article link? I'm still trying to figure out where I found it initially.

I'll have to go find it when I have time but I read a piece back in December that basically amounted to "The driving force behind the resurgence of vinyl and other analog source (including reel to reel and cassette) is that it is virtually impossible to put DRM on an analog recording."

That's the biggest factor 'cause hipsters don't buy that much new stuff. Mainly because they are broke.

But with DRM doing everything from making a disc impossible to play on an older CD player to DRM measures bricking phones or media players to having outright security holes in them, people are gravitating back to stuff that gave them control.

Much of the analog source material is coming from independent labels too.

Umm -- some of us Luddites knew that a long time ago. As long as media players had analog line level outputs, said Luddites were OK. Paranoid but OK.

Nowadays, the great breakthroughs in digital technology have been slowly but surely eliminating analog access to the analog "datastream". I'm sure that's solely been in the service of perfect sound forever, and not some nefarious scheme to control access to streaming or "leased" content!

According to the record companies, just because you have program material on some sort of media doesn't mean you own it. You are just licensing it for your personal use.

You're correct, sir. That is absolutely true* (and was always the case) -- although the industry always seemed to tolerate customers selling (and buying) used but authentic copies of analog media (records, tapes, piano rolls, etc.).

I've been contemplating getting another turntable after 30 years without one. I believe (IMHO) that there are some recordings just meant to be heard in that format.

That's going to be a big problem for video game preservation of the newer generations too. Games that need to be authenticated on a server in order to even boot, what happens when that server disappears in the future? What about digital only games?

Old cartridges will always be able to be played.

Yep!
