    Generally speaking, I guess, if you ignore the millions on food stamps and unemployment, the businesses and livelihoods ruined and those that have passed away, due to 2 week quarantine with no treatment. We will get by, but it's pretty ugly for some people out there. I could go on, but be cheerful.

    Coulda fooled me, in the rare times I watch political news it always feels like dejavu from watching them as a kid.

    Same bullshit, same attitude, same blatant lies and manipulation. Sometimes by the same people, no less.

    True, the world is just as beautiful and at the same time horrific as it ever was. Plagues, wars, famines, oppression, and the like come and go with metronome regularity as they always have.

    CNN doesn't have as much news to report. People are suffering withdrawal. Instead of 7 of 10 headlines on CNN.com about Trump, it's maybe down to 1/2 a headline now (the indirect one against Trump from Birx).

    Instead of focusing on the good things Biden is doing (consideration of direct delivery of vaccines to nursing homes, looking at our supply chains, and calling out China - LOLZ - he sure pissed da f**k outta China - and I'm glad we did), people want to focus on the dumb things.

    It's like what Agent Smith said in the Matrix. People love suffering. Not having something to be really angry about leaves a hole in the heart.

    Here's from my local friends:

    Left-Leaning Folks: At least Biden is trying to non-f**k the country.
    Right-Leaning Folks: f**k you Biden, gas going up to $3/gallon. f**k Dems for raising my gas bill and punishing me.

    Mainstream Media is a business...we all know that.

    I actually kind of like Biden. Heck of a lot more than Obama who seemed to me to be a lot more interested about his legacy - his ego. I'll give Biden a pass, the benefit of the doubt, for the humanitarian disaster at the border* - will blame his advisors on that one. Will wait and see.

    Indeed, American news is so boring now. But the world's a better place for that.

    On BBC News website, a video ad from Amazon pledging to be carbon neutral by 2040 — followed by news that Amazon admits that their drivers pee into bottles (which they had denied earlier).

    In NL the vaccine shots with Astra-Zeneca are delayed again.

    The vaccine is not mandatory. Guess what? All the gossip and fear spreading which comes down to "does it really work" is obstructing a campaign to return to pre-Covid-19 life.

    Seriously, 2 years or more in this Covid-19 life and a big recession will hit everyone and recovery (especially economic) will become more difficult. This is the 21st century and we are privileged to have a vaccine so soon after a big outbreak.

    Yet there are still people holding on to superstitions and old books because vague reasons and mystic revelations.

    I do not want to pay the bill for the stupidity of spineless politicians and superstitious people, but I fear I will.

    I got the full there is no covid, it's all a scam argument from a friend I haven't seen in a while.

    Don't know how anyone can think this. Bottom line is that scams need beneficiaries, and none seems to be much benefitting from this alleged scam. Some pharma companies will add profit (but when don't they?). Yes, it may have been convenient for some governments to get people off their streets for a while (but when isn't it?). Yes, most governments and health authorities have totally failed to get to grips with what restrictions, when, and for how long, are/were appropriate --- and if this has cause anything, it is politically embarrassment, whether they admit it or not, to most.

    Bezos has done well. Boris's friends in UK (and similar regimes, probably) have pocketed a few million for not doing much. But all that would have happened anyway.

    There has been vast suffering, national, political, economic and personal, worldwide, yet this is all said to be a scam? I don't even begin to buy that.

    My reality may be just as ill-informed. I have not, for instance, personally, lost any friend or family to covid. But I have no reason to think that that those who have are lying, and even less to think that those lies are part of some huge conspiracy.

    But covid has been born into a world already running on fake news and lies.

    It's a mad world. We need inoculating against more than just covid!

    I read about the parents who came from a communist country. I came from a communist country and I can tell you that comparing to the level of indoctrination in North American educations system the communists schools were science oriented, free of indoctrination, except for the falsification of the history of Soviet Union and some spin on polish history. But the teachers were doing their best keep it clean.
    When I came to Canada 30 years ago I my son went to school I was stunned by how ideological were the teachers. Of course there were good, dedicated, free of bias teachers as well and my son was lucky to meet many of them.
    But it was nothing comparing to a methodical subtracting from human knowledge, literally dismantling the foundation of the Western Civilization piece by piece, and prosecution of ideologically impure. Concordia university "scientific" team is working on "decolonization of light". Both electromagnetic wave theory of light, and photon theory were apparently developed to impose racial domination. And we cannot have that.

    I have a friend who is an MD/PhD who teaches at a medical school and he has chosen to practice kitmān to keep his job. Jordan Peterson (who wrote the standard textbook on the psychological aspects of totalitarianism and then had to fight for his academic job in Canada) and others have been writing about this tilt in our culture for years.


    It's important to note that this "dismantling" is the expression of long held and foundational tendencies/ideals within western civilization itself. In other words certain axiomatic aspects of the Enlightment (e.g. nominalism, Cartesian self, etc.) lead just to where we are at. Reaping what we have long sowed and all that...

    My job has been pushing slightly on this as an "awareness" thing. However, people forget about this stuff after we do an online training class. It is mostly due to I think "look good in public" so more people do business with my employer. The usual.

    However....some of this stuff is also done due to want to avoid bad feedback/press + want to avoid any discrimination claims from the state/federal level. Here's an incident that recently happened and it was kind of a big deal in my world.

    You are right, that is the most disturbing aspect of it. It is almost impossible to defeat any great civilization from outside. What is happening is suicide.

    Putting this here and a chapter title on it. Sometimes good questions in PMs. This one is about measurements and why I'm doing different and IMO cooler measurements than the typical shit ("SINAD" [distortion at a specific SPL at a specific frequency], FR, etc.) because the typical shit really doesn't tell us very much.

    Oh, NFB and output impedance, (along with power) definitely makes a difference with respect to driver "grab". I think it's probably more power than source impedance ... but if we figure that that high source impedance = power being wasted into heat as opposed to going through the driver, it makes better sense. For those not aware, feedback from the output can do wonders for lowering source impedance (and lowering distortion), at the expense of less gain.

    I have a amp with selectable output impedance, one is about 1.3 Zout, meant for driving 4-ohms speakers and the other is about 3.5 Zout, meant for driving 8-ohm speakers or headphones. The switch definitely makes a difference even for 60-ohm headphones. In theory, whatever setting should not matter because we are getting Zin/Zout >>> 5, but it does. The high Z output is "warmer" / "lusher" or more precisely softer. What setting I use depends on what sounds best to me subjectively with the gear I happen to be using.

    With respect to dynamic range, I think the attack burst envelop tells us a little bit... the nature of distortion isn't so clear cut and according to perfect theory. We have to understand that music was engineered, recorded, mixed, mastered, with flawed gear in min - typically dynamic drivers driven by fairly high-power class AB power amps. So I think the attack envelop with a bit of overshoot on the 500Hz, 1.5kHz, and 4.8kHz matters a bit. Note that the Utopia has these qualities on its attack burst envelope measurement.

    The other aspect to "dynamic" range could be compression. I haven't attempted to do this with headphones. I know with big woofers, this is easily measurable (and audible) after they are powered for a period of time where the voice-coils heat up. Anyone who was worked in live audio and been dealt inadequate wooferage knows this. JBL use to provide compression vs. sustained power in their woofer datasheets.

    OI and "damping factor" (electrical not physical) have an inverse relationship, but is it 1 to 1? In other words, damping factor does not simply = (inversely) OI correct?

    Damping factor takes impedance of transducers into account.

    Df = Zin / Zout.

    Last I looked at transient behavior, damping factor does make a difference. However the test scenario I ran considered a wide difference with Zout (1.5-ohms vs 50-ohms) with a 30-ohm Grado.

    upload_2021-4-7_15-25-35.png

    Now the big question is whether a smaller difference in Df (say between a 4-ohm and 8-ohm transformer tap), where I claim I can hear the difference, will yield notable differences in transient type measurements. Then there's always the question of how much to "zoom-in", because many times, plotting these things out so we can see things visually, at least on a coarse level, will necessarily reflect how sensitive our ears can be. And then again, different ears, different training, different sensitivities. As I love so much to point about, Amir couldn't hear the 50db 35db SINAD plate amps in the JBL LSR305s which he described as "smooth, very realistic sound impression, beating many "hi-fi"
