Your definition for wow, flutter, and jitter are too narrow. They are all errors in signal timing.

Who cares if CDs throw out ultrasonics? You keep coming back to this and it is irrelevant. You can not hear ultrasonics. You hear the effects of ultrasonics which are beats and harmonics in the audible range. CDs can capture that perfectly. As I said in the original reply unless we are talking synthetic signals designed to interfere only upon playback the effects of ultrasonics are created in the studio, not your living room. CD delivers this perfectly

No, it does not take cheap turntables to cause noticeable groove wear.

Jitter, wow, flutter, are all the same thing - error in the time domain. Jitter is not unique to CDs.

I'd like to see said square waves, as I implied cutting one is impossible without a theoretically perfect (monopoint) stylus which has no momentum. Forget about even getting close when reading with an elliptical or other stylus of any physical dimension.

You also appear to be confusing where and when the filtering for CDs takes place. I am not arguing 44 is an appropriate sampling rate for recording, but rather distribution. If ultrasonic frequencies causing audible interferences exist in the studio then the audible tones will be recorded and survive downsampling to 44.

As for durability, I can show you the spectrum of a progression of needledrops proving one play decreases HF response measurably and one play with improper (as little as one gram) anti-skate ruins channel balance. Permanently.

They may sound ok to your old ears, but that only proves my point that 44 is plenty for humans.

That's needless speculation. Testing this shit is quick and easy.

A bloody $30 DAP (Sansa Clip for example) can demonstrate better than -90 dB noise floor, better than 90 dB of channel separation, frequency response flat to within a hair of a dB, and distortion numbers which would make an 1990's recording engineer cry.

Fact is competent audio is EASY, and commonly done with the cheapest of components today. I am sure there are examples of failure readily available, for when there are thousands of examples on the marketplace it is no wonder dozens are broken.

Point is your claim of "often" finding broken components is just wrong. Show me some numbers, I can point to hundreds of competent RMAA tests of commodity components and systems to argue my point.

Of course mechanical components are the weak link and always have been. But that's not what you originally said - you proposed that it takes a special amp to enjoy an LP when the amp is far from the weak link.

The frequency response of an LP is grossly overrated. Sure there is 40kHz content possible, the first play, and 40 dB down. Since I rather suspect you can't hear 1/2 that frequency, much less that far down, it is moot.

LP's main disadvantages are:
noise
wow/flutter (jitter)
durability
non-linear frequency response
If noise was the only one most of us would never have upgraded to CDs.

Your description of how aliasing comes into play is simply wrong, as it assumes improper filtering before sampling. A square wave is nothing more than a collection of sin waves. A 15kHz square wave can not exist after filtering content below CD's Nyquest, and more importantly can not exist period on an LP. I'd like to see someone draw just how a square (or even triangle) wave would exist on a record groove. Bonus points for demonstrating how a non-theoretical-point stylus can track said groove.

If audible tones are affected by supersonic harmonics they were affected in the studio and said effects were recorded. End of story unless we are talking artificially created tones intended to cause interference only upon playback (See The Hafler Trio).

If we are talking supersonic harmonics designed to interfere on playback, ones which did not exist during recording, then we also must assume you have some brilliant speakers to be able to produce these tones in a linear fashion and not just create a bunch of HF noise.

I can show you plenty of LPs with content > 22kHz, but I challenge anyone to show needledrops with signal, not noise, that high.

In this day and age when one can order $0.50 DACs with noise floors 90dB down...

In this day and age when even the $10 CD players at Odd Lots oversample (so as to push the filters into ultrasonics)...

You are describing systems defective to the point one needs to go out of their way to design one with such problems.

If we accept that 16/44 PCM is all that is needed for accurate reproduction in sane listening environments (96dB of dynamic range = instant ear damage volumes in all but the most theoretical of rooms) then we must accept that all the "euphoric" distortions of analog/tubes/vinyl can be reproduced with said 16/44 PCM.

Again you are describing mastering preferences not format issues.

An LP on a high end turntable through an amp with less than 1 db of distortion or noise

Yea, because the amp is the weakest link in that chain. LOL

It will sound better than the same record in CD format

This is nothing more than an unsubstantiated claim that LPs are capable of fidelity beyond what 16bits @ 44.1 kHz PCM can deliver.

Where, exactly, do LPs have the advantage?

Except this isn't a problem that needs solved.

Kinematic GPS solves position using the carrier instead of the (time) code. Since the carrier length is ~19cm you're instantly much tighter than is possible solving with the time code.

And, as others above me have said, (regardless if you're carrier or code locked) a 3D solution needs four birds visible because of the receiver's inaccurate clock. At best an atomic clock on the receiver means one less variable to solve for = one less bird needed. Today when we have a full constellation that is just about never a problem unless you're in absolutely horrible terrain with very high horizons, and in that situation your PDOP is going to be so bad as to render moot any positional accuracy gains seen by better clocking.

Not to mention the Russian GLONASS birds up there, and Europe's if they ever get their act together, and the L2C frequency... point is there are lots of inexpensive ways to increase accuracy which don't rely on an expensive clock chip.

The time to short the stock is well past.
One shorts when public information is low and you have special knowledge of the situation, be that insider information, a unique knowledge of the industry, or particular experience.

Shorting Sony at this point in time, when all the smart money (which knows more than you) has already set a rational price based on reasonable odds is nothing more than tying your hands.

Unlike a traditional (long) position you would have locked yourself into a time window, preventing you from a full range of actions based on later information.

I hear what you're saying regarding vision, and while that wasn't the limitation I was thinking about upon further thought perhaps you are right.

I was thinking about the (currently) uniquely human ability to judge range and wind through a combination of complex and subtly visual clues, rules-of-thumb, intuition and experience (the way tall prairie grass responds to a 10mph wind in late dry summer is different than how it responds the day after a rain, etc). There is no reason, though, that a sufficiently complex expert-system paired even with today's camera technology probably couldn't do the same.

In all seriousness; how long until the military just deploys (via parachute drop, or soldier) robots into decent vantage points and then just get them to identify targets and have a remote operator push the button... scary stuff.

The value of a sniper team is not just in their targeted lethality, but also in their scouting, observation abilities, and ability to move. A robosniper limited to a fixed position is just as much a sitting duck as a static artillery tube.

A robot which finds its own cover and provides a remote control gun barrel might be within the limits of modern (or foreseeable) technology, but one which is capable of moving stealthily from spot to spot? One which can climb stairs and over rubble in a bombed out building in the afternoon and craw through a drainage ditch that night? One which is able to read the wind and range passively without giving away their position through the radiation of active sensors? No, I don't think such a robot will be seen in my lifetime, likely not my (unborn) children's.

As it stands now savvy users can simply check out a epub library book to their PC with Adobe Digital Editions, seamlessly remove the DRM with calibre, then convert and upload to their Kindle with one-button via your Kindle's free email address. If Amazon doesn't make their service work without a PC I've gained nothing.

I almost died of the analysis-paralysis suffered looking for an ebook reader, and finally settled on the Kindle as the best bang for the buck today. While I feel epub is the future (especially now that google has weighed in) with calibre I Just Don't Care.
