I have almost never found that to be the case when listening to a live orchestra in a good hall. I remember last summer, sitting in the National Arts Center in Ottawa, listening to the NAC Orchestra. There was a woman playing bass who was in my line of sight, and not very far away. Her appearance, her instrument, and her attitude all caught my attention, and I wondered what her playing sounded like. I found it quite impossible to separate the sound of her instrument from the sound of the orchestra, even though I could see her hand movements.
Now, it is possible that if I had the opportunity to listen to the same passage over and over again, like in a really good recording, I might have eventually been able to separate out the sound of just her bass (as opposed to the other basses, so maybe would need a video with really good sound). Focus, as Jann said. But there was really no way to do what you described above while listening to the orchestra live.
Heck, I have listened to duos where it was hard to tell which was making what sound! (And that's live, not amplified, no electronics to blame.)
Qusp, "I have you now". Show me a 25W resistor that is the SAME SIZE as the one in the picture. To give you a reference: The MAXIMUM length must be less that 2 inches and diameter perhaps around 1/3 inch.
Just give me the device # from the catalog that you referenced or any other source.

you said anywhere, but.. well given what hes charging, it would be pretty easy to get something custom but here's something close, so i'm sure they would have no problem supplying it

model NKNP
again, a minute searching
John, not to be impolite, but you said the shell of the resistor had a coating which is what makes it a quantum device.
If I may inquire, does the shell have a coating, whether on the inside diameter, the outside diameter or in between, that is or contains a pn junction?

dont be silly, you could very easily get them to make you a batch 10mm shorter than their 61mm x 8mm 25W part, as if 25W was actually needed. you could get this custom batch, quite possibly, with the cost of a couple BBs. to claim that is a special feature somehow is ridiculous
kelticwizard: its nanocarbon filler apparently
In the sense you describe it, where one particular instance of a number of instruments which are playing in unison, physically very close together, yes, it would be very difficult. I was using the term 'instrument' in the context of sources of musical sound which are in at least some sense individual, different, either via tone or the score, from that which is nearby, acoustically.
Interestingly enough, on recordings often it actually seems to be easier to separate, because of the use of multiple microphones, or layering of tracks: each captures its own little sound world, its own little 'pocket' of echos, etc, which is then possible to 'see' in a well recreated soundscape.
A good example of this in the pop world is Michael Jackson's "Bad" - at one particular moment there can be something like up to, say, 20 separate sound elements in the mix - these can all be discerned as having a separate existence, a place on the stage so to speak.
The ceramic 'shell' covers the resistor entirely, and seals the resistor inside with its end caps. It is the outside of the ceramic shell where the action is.
Pano, no I don't think so. Once your system gets enough resolution that you can actually separate the diverse strains, you can then focus on a certain set and the others sort of drift away. Similar, but not identical, to the 'cocktail effect'. It is not limited to separating the music from extraneous noises; you can also focus on a specific instrument or voice and then the others 'drift away'.
Surely you're not suggesting that your stereo system separates out the various strains and somehow steers one to the forefront and the other to the background 😉

That would be skin effect then?
The higher the frequency the more effect.
Its a filter. Still not secret technology.
So the Idea<<probably completely wrong is to slice off the signal in the outer edge which is probably hash it HF.
Ie you or should I say I am saying that you are using skin effect to "try" to separate the frequencies.
For this "Dream" to be true the ceramic would have to be conductive in some form.
Think I'll give it a miss!
Link,
Skin effect - Wikipedia, the free encyclopedia
So lets put lots of tubes inside each other with a semiconductor coating and split the frequencies based upon skin effect! then short the one's we don't want through a resistor and dissipate as heat.
Just a guess of course! Where are the Grays..😱

Admiring the performance art. And, of course, smiling as they realize how easy it will be to take over Earth, if people really are stupid enough to take this stuff seriously. I guess now the pointless excuse is that the surplus resistors bought for one of the batches have a 25W rating (if even that isn't a tall tale as well).
But this is off the topic of the thread, which is Measurements and Double Blind Tests. John, do I take it that you still have no data to present?
The resistor shown is I believe a beryllium oxide resistor, used for high temp stuff, we discussed it in an earlier thread.
This is why I love diyaudio! There are people who are knowledgeable to debunk myths and are willing to show data with it. Not to mention the double blind tests, et al. In most forums, people just simply "follow" and believe what is said when someone "credible" says something (or anything) sounds great. And the followers simply believe this person just because. I really appreciate this kind of discussion and just wanted to salute SY, DF96, Cal Weldon, Fas42, BR2600, et al! Thank you!

If I may be allowed to ask:
1. What kind of ceramic is used in the "shell"?
2. Is it the same material all the way through the tubular shell, or are there other substances on the outside circumference of that shell-I'm not talking about the nanotube packing material, I mean other substances being part of the solid tube?
As you should be. I would think substantial (your words) is quantifyable and measurable. OTOH being a quantum device trying to measure it might destroy the effect.
Ed how are those measurements coming?
Actually, yes - it is very akin to that. A surprising effect! The systems I've head it on tended to place noise and music in different sonic spaces, sometimes even distortion. It's amazingly cool. But it makes sense when you stop and think about it. Tape hiss, pops and clicks, surface noise and even some distortions are all in their own space, they don't have the same spacial cues as each other or the recorded sounds. Once a system is clean enough to resolve that - you hear it. (it is rare, tho).
Exactly. What you have been describing is "hi-fi" sound. It is very nice, but it is not what live music sounds like. Don't get me wrong, I would not like to hear an orchestra in my living room. I like the sound of a good recording of an orchestra in my living room. Audio types often go on about "air" and "space" and "precision", for example being able to hear each individual note of a guitar, each individual plucked string, the tiniest details of the sound of the guitarists fingers interacting with the strings and frets. And that is all good and really cool, and I like it too, but it is not even remotely like what it sounds like to listen to a person playing a guitar in a room. Unless maybe you are sitting with your ear against the instrument. But it's what a good hi-fi can sound like, assuming a good, close-miked recording.
And of course, pop recordings like the one by the late Mr. Jackson have no acoustical analog -- there never was a live performance that sounded like what is on the record.
