I've not looked up the specs, but as one who is slightly familiar with real flamethrowers, (and I doubt this is one), then you have to be really careful...if not, you're just as likely to cover yourself with flaming liquid as you are to "have fun"...or whatever the hell you're trying to do with it.
This. Real flamethrowers spray burning oil on stuff. Think napalm. This really is "not a flamethrower", it is a glorified tiger torch.
I'll let you in a little secret: cars are *recycled*. There's thousands of pounds of metal and materials in every vehicle - did you think that would just go into a landfill? Of course not.
Indeed. We have big fenced lots full of cars as far as the eye can see that you can go take parts off of if you need something to replace on a running one.
True. The way they are supposed to work is the money disappears up some executives ass when the majority of the workers that paid into it their entire career reach retirement age.
used helium gas to assist his patients who wanted to commit suicide. I believe it is still used by organizations such as Dignitas for the same purpose.
Tell me, what of my personal data beyond billing and shipping data for my most recent order would a Mom and Pop shop need?
I don't collect any data from anyone, but I use Google Analytics on some websites and ostensibly it can collect enough data that Google sends out emails to admins telling them all to check their settings to make sure they are compliant with GDPR.
Usually the changes have been gradual such that life had time to adjust.
Well except for the fact that the 1.2C rise in the last ~150 years has just happened to coincide with the greatest global improvements in life expectancies and standards of living the world has ever seen.
When those metrics start declining I'll worry. I doubt that will be anytime soon, doomsayers notwithstanding.
There's also a bit of a ritual involved with pulling it off the shelf, out of the giant sleeve, and setting it on the turntable and setting the stylus and all that.
Rolling a splif on the album cover also. Don't forget that.
I don't think we even got into the differences between 1-bit (like SACD uses) and multibit D/As. They both have their pluses and minuses (sorry!); but if you crank the sample-rate of the single-bit (Delta-Sigma) converters up high enough, they are essentially the same (until you try to start EDITING in the Digital Domain. But that's another story!).
But I agree: The "Perfect Copy" ONLY applies to Sine Waves, and is ONLY in theory, depending on how "close" you want to look...
No argument here. I personally prefer the sound of a good multibit DA for 16/44 but find delta sigma better for hi-def 24/96 and above. My budget certainly factors in as well........
But I'm talking about the DAC chip itself; not all the stuff around it that audiopiles lump together and call a "DAC".
Burr-Brown, ESS, Wolfson and many others make DAC chips, often with a range of quality and price. DAC device makers take those chips and add their own filters, output stages, etc. People pay huge dollars for hand trimmed discrete resistor ladder DACs. I understand the theory behind digital sampling, but the actual functional implementations of that yield vastly different analog waveforms in the real world.
But they are not insignificant, as you can hear a very audible difference between the same source on the same system with different DA converters. It may well be you get closer to perfect the more you pay, I would not know, but I know there are big differences even in high end gear.
And I would not be surprised if those same subtle sort of differences were manifested in the original A/D conversion as well, though of course would have no real way to know.
If you use a DAC that creates discrete steps, and feed the output through a perfect 0-22kHz lowpass filter, you get the original signal back.
Because it is impossible to create such perfect filter, a common method is to convert the 44 kHz sample rate to a much higher one, say 1 MHz. Feed that through a DAC, and then use a much simpler lowpass filter to get rid of anything above 500 kHz.
As far as higher harmonics: if you can't hear a pure sine at 30 kHz, you cannot hear the harmonics of a 15 kHz fundamental either.
That would be a Delta-Sigma D/A converter, which is most common nowadays and quite different from the original multibit type (see http://www.rane.com/note137.ht...). I think the point is there is a whole lot of filtering going on, and that is where the subtle differences emerge. That perfect copy is in theory only.
You can demonstrate this by taking an analog waveform, feeding it into a digital sampler, then converting that digital sample back into an analog waveform. The beginning and ending waveforms will be identical despite the latter one having been converted to digital and back to analog..
Funny then that you can hear such a huge difference between different DA converters then.
Simple in theory, but maybe not so much in actual practice.
Most "audiophiles" don't possess the necessary acoustic environment.....
Yes, indeed - THIS!!!!
I have a pretty decent system, but a while back I purchased a calibrated microphone (UMIK-1) and learned to use the REW software - https://www.roomeqwizard.com/ - and started down the path of treating my listening room. With the simple addition of some homemade bass traps in the corners and some wide range absorption at the first reflection points, the audible difference is absolutely huge (and I can also objectively confirm that with impulse and waterfall graphs). Much larger than could be had by spending that money (which was not really much) on hardware.
If you are listening in an untreated room, you really are missing out on a whole lot.
Listen to an analog mastered recording from the early 70s, and compare it to one from the early 80s, right around when CDs came out, but before digital recording was the norm, and the quality difference is huge. I would expect a modern analog recording to sound really, really good if the technology continued along that path, and it probably sounds great on vinyl without any DA/AD steps in between.
I grew up with vinyl, and then transitioned to CD audio, and for the most part I am happy with the sound (on a good system, with a good DAC). I've started to dabble in 24/96> but really don't find the improvement that huge. I still have a high end turntable and cartridge, but so far have felt no need to hook it back up. A true complete analog signal path created with the most modern technology might give me a reason to revisit that idea.

They have had worse.
You need us more than we need you.
Yeah, you just keep thinking that.

Indeed. We have big fenced lots full of cars as far as the eye can see that you can go take parts off of if you need something to replace on a running one.
Aren't the German automakers highly unionized as well? Blaming GMs woes exclusively on the UAW seems a bit narrow sighted.
Indeed. Another reason I prefer German cars, as if there were not enough already.
Speaking of tracks, what is its time around the Nurburgring?
True. The way they are supposed to work is the money disappears up some executives ass when the majority of the workers that paid into it their entire career reach retirement age.
I'd mod the AC insightful if I had points.

Trump will one day be gone, but the USA's untrustworthiness will take much long to repair.
I also was taught in typing class to single space after a comma and double space after a period, and I have continued to do that to this day.
Have to say I gave up on that whole indenting of paragraphs long ago though.

Just pointing out that CO2 has not been a significant detriment to the welfare of the human species up until today, May 7.

Apart from the fact America is not global, I don't see the connection to climate change.
I suppose it is possible that some people are so worried about it they become heroin addicts.

If it was up to me I would just say "no ICAAN for you". We don't do business there.
