Do tell. I use mains conduit cabling....don't ask me why...it was a mistake..not flexible..at all
I've found a new low in upgrades, the fancy air compressor I purchased is a decidedly underwhelming improvement and very cost ineffective.. LOL Replaced the WISA that came with my recently acquired ET-2 arm with a new Silentaire. Improvements are audible, but debatably a bit beyond the point of diminishing returns. All of that damned plumbing is leaking too, and I am not talking about the big leak, err air bearing either.. LOL
I expected anti-climactic, and that's what I got. I guess I am not good at self delusion or something. It's also to my disappointment not nearly as quiet as I had expected. (30dBA at 3 ft)
The reasoning was that I would get longish run times between compressor kicking in to recharge things, so far that's not been true. Second arm will arrive later in the year, this compressor will provide the air for both.
I've got some quad core hitachi stuff I was given by my local retail emporium for free in 1994. You can't even read the writing on them any more!
Kevin: When I once pondered an air bearing I had a shop compressor in the garage and I did wonder about having just a local tank that you filled with enough air to last an evening then recharged it in the garage. How big a receiver would you need? I assume it's related to how good a regulator you can get (air being a compressible fluid and all that).

Or, get a 20L tank of Nitrogen at 3000psi.
Scratch that. Next we will be hearing "No you need Helium, it improves the highs and gives a deeper bass. No, argon is better. blah, blah, blah".

I would love to DBT a couple of "Golden Ears" that claim they can hear differences in speaker cables to see if they could tell the difference between these two. Difference, 35 years and what I believe to be chlorine from the PVC attacking the copper. It only happens in one of the twin cable wires.

Fixed pressure spring regulators with a constant outflow are plenty stable. And something like a kegerator sized bottle, you can go up a couple thousand psi, if you have the pump. 🙂
SF6 really brings out the low end.

I actually considered a large tank that I could either drag out to the garage or drag an airline to from the garage to recharge. The idea of dealing with this in our climate during the winter months put the kibosh on the whole idea. 🙂
I may have a leak or my grasp of physics is even poorer than I acknowledged.. I figured I would get about 30 minutes of run time on the gallon tank before the compressor needed to run to replenish it, at any pressure I was likely to use. After fixing some leaks I am up to about 6 minutes now.. LOL
In the coming weeks I will investigate further.. It could be that the surge tank is leaking or something else is. My initial thought is to just disconnect the arm temporarily and pressurize the rest of the system and monitor the pressure and see if it is leaking down. The arm of course is a big leak! At 9 psi probably around 3 liters a minute.. It may also be the settings of the compressor's differential pressure switch, widening the range would increase the time between runs, but lengthen the time it runs when it finally does.
Dry nitrogen in a high pressure tank was recommended, but given the nature of the plumbing used, the likelihood of leaks, and the fact that I probably play vinyl for more than 20 hours a week I figured that would be uneconomic at best.
Edit: I also plan to get a second one of these arms later this year so have an overkill air supply no longer looks so crazy as I will need between 5 - 6 liters of air a minute at 8 - 10 psi.

Kevin, just as long as you know to paint all the joints with a cutip soaked in dishwashing soap (e.g. Dawn). Bubbles form at the leaks so it's really easy to tell.
Yup, that's the plan. I talked to someone with one of these compressors and an ET-2 arm, apparently this is normal, but if I can get a bit more run time it would be good..
*in a high pitched voice* "wow your turntable sounds really good!, uh I think we need to open a window..." 😀
No external energy or radiation source is required, just placing the wine on a 'coaster' (as is JC's Cognac experience) or a small glass vial 'depth charge' into the bottle or glass brings about the changes.
In the case of red wines the 'alteration' takes some time and is reversible.
The subjective effect is clearer appearance, smoother fruitier taste and side effect is lack of 'hangover'.
I do not have the answers as to how or why, but do I trust the wine judges findings as absolute evidence and reinforcing 'novice' findings.
Scott, I am still to make an additional alternative 'bad' mixture that I will use to repeat the experiment.
The result I expect will be strong contrast between the two 'treatments' that ought to survive upload/download based on prior experience of normal vs treated files.
When I am good and ready I will perform this experiment to my satisfaction and then post the result to Dropbox.
At the present I have plenty on my plate not the least of which is dealing with a 25yo young punk who does not understand that his workplace bulling toward toward one older than his father is not kosher.
Come Tuesday he will learn the true meaning of 'every bully has their comeuppance'.
Dan.
I understand your thoughts here, but expectation bias is not the driver.
The subjective descriptions from trained/experienced sound engineers preclude any such summary.
Dan.
I very much doubt that, you are having too much fun pretending you have something. Actually putting up evidence would demonstrate the Emperor's nudity, plus it would require you to actually possess what you claim.
But, Dan, virtually everything you post here shows that you are exceptionally susceptible to self-suggestion, much more than average. You also have had direct contact with every "evaluator", and I have no doubt that you are very convincing and infectious in person. None of the anecdotes that you have presented here "preclude" anything at all.
Very good points. I have also suspected Dan is somehow unintentionally influencing his test subjects to report favorable results. It's why double blind testing has to be used in the real world. The experimenter who interacts with the test subjects is not allowed to know or deduce what the test subjects will be listening to. That is true even if the experimenter thinks he or she knows for sure they have not influenced test subject reaction or opinion in any way, usually they think they haven't when they have. All it takes is as little as a brief expression on one's face or an inflection in one's voice that one is not even aware of.

Facts is facts, believe or disbelieve, you takes your choice.
Ferrite split core inductor, same but different.
Dan.
You remember that there's also available litz cable for mains power usage which ist much more flexible 😀?
Best regards!
Yours' are alternative facts supposedly.
Best regards!
These things have been around for decades, in a past life I was peripherally involved in the wine and food trade. We sampled several of these things in the presence of top professionals. None of them did anything ever.
I see now ultrasound and copper bars are being pedaled both of which are well known to alter the taste of wine. Sy and I once scrambled to find some real pennies to drop into a particularly shite bottle.
These devices are being sold into a market of folks spoiled by instant gratification and ignorant of what the normal process produces. The wording of the positive reviews clearly shows that.
Are these what you mean Scott? Neat trick.

Yes, they modify the taste they do not create the flavor profile of a cork finished properly aged and stored wine. The folks that have experienced both are few and far between.
