For line levels, for me, nothing else comes into consideration but thoroughly gold-plated, gas filled relays. Wrong. For speaker-level signals, a combination of both silver-plated and gold-plated heavy duty contacts with strong spring action (meaning contact pressure) are a good choice (if one has to switch speaker-level signals at all, something I don't like to do at all). Wrong. Switching an audio signal at microphone- or phono cartridge levels is almost not possible without suffering from signal degradation. Wrong. Keep up the good work, Sander! |

The pressure on those atoms would be gigantic (try working out grams on nanometers squared and they'd be pressed back into the metallic lattice for sure. The 'mountains' are leveled, then some other atoms will make contact, reducing the pressure, etc. etc. Three points would be a mathematical, not a physical maximum, it'd rather be the absolute minimum (say if one has some (metal) surfaces stacked in zero gravity) I guess a springloaded ballbearing transport table with a slab of metal on it would make for an adequate mental model. make that two tables, one overturned, on top of each other for Robert :-) Rudy |

It doesn't appeal to me either, but this is the world we live in. In fact, audio equipment exhibits a well known quantum effect, in the form of background hiss. The purpose of my questions is to illuminate the fact that we have a tiny signal that passes through a complex interface. According to the literature, the interface is composed of "nanowires", a term coined to denote conductors, and the current flow through these is quantized. I do not give much concern to the incorporation of these devices into hifi equipment. But Arny Krueger is pushing his device like the NBS platinum meter. An interesting discovery was made about that bar afew years ago, now that it is a secondary standard to the atomic meter. The bar is shrinking. Either it is evaporating, or internal stresses are causing it to change shape. So what I'm saying is, we cannot bank on relays for ABX comparison. They seem comfortably simple, but they are not. |

I do not give much concern to the incorporation of these devices into hifi equipment. Good idea because reed relays are common signal-handling components in quality equipment for audio production for decades. As I said before, the ruthenium plated reed relays we used had been recently used by a widely-respected manufacturer of studio mixing boards. Morein's vendetta against reed relays is yet another example of his lack of familiarity with audio production equipment, and audio in general. But Arny Krueger is pushing his device like the NBS platinum meter. This is nuts. I'm not pushing the ABC RM-2 relay module at all. RM-2 has been out of production for what, 20 years? However, no matter what Morein says - Stereophile never published a review of the ABX RM-2 relay module. |

I know lots more about him than I know about you, and I don't call you a sockpuppet, because you are not, And he is either someone just pulling people's chains with his anti-scinetific bull ****, or he's a sock puppet who actually believes the crap he says.

Would anyone care to guess how many points of contact can exist between two nonflat surfaces that are not soft enough to conform? Irrelevant to the relay contacts used in the ABX RM2 comparator, because those contacts are not solid ruthenium. Instead, the ruthenium is a thin plated layer desposited over softer copper contacts. Since the question is irrelevant, there is no logical purpose in answering it. Besides, its rhetorical. That would make two good reasons not to answer it. It is very important, because the actual surface area that is in physical contact is extremely small. This makes the bulk conductivity of ruthenium important. Prove it makes an audible difference. Prove it doesn't. Can't prove a negative. You still have the burden of proof. You made the claim, you supply the proof. Mikey, we reject ABX, and we reject Arny's ABX device, until such time as it is proven to be transparent. The rest of the world doing audio research already has done so. We will not permit adoption of this technique by the public until this is done. It's not up to you. It's already been adopted by real audio professionals the world over. As I said, we will not allow it to be adopted by the public. "Real audio professionals" do not use it either. That must be why it is the standard. ABX = A Bull**** Xperimeint |

"Arny Krueger" wrote in message ... "Robert Morein" wrote in message I do not give much concern to the incorporation of these devices into hifi equipment. Good idea because reed relays are common signal-handling components in quality equipment for audio production for decades. As I said before, the ruthenium plated reed relays we used had been recently used by a widely-respected manufacturer of studio mixing boards. Morein's vendetta against reed relays is yet another example of his lack of familiarity with audio production equipment, and audio in general. But Arny Krueger is pushing his device like the NBS platinum meter. This is nuts. I'm not pushing the ABC RM-2 relay module at all. RM-2 has been out of production for what, 20 years? However, no matter what Morein says - Stereophile never published a review of the ABX RM-2 relay module. Arny, permit me to clarify. I would love to have an ABX device. Even if it were one of yours, I would treat it as a treasured resource, unless it obviously contradicted certain observations about amplifiers that have the same certainty of audibility as you have with speakers. You reached conclusions about amplifiers that arouse in a number of us, deep suspicion. Even if someone was incapable of distinguishing the difference between a Pass single ended design and a Yamaha, it has little meaning for us. Speaking for myself, I acknowledge that there may be audible equivalence classes that transcend price and construction. Still, this is not the same as declaring an axiom. Speaking again for myself, it appears that reliance on current methods of measuring amplifier specifications produces the appearance of technical equivalance, or "proper operation", while the latter is not a properly defined term. I know that you are convinced of this through your studies of the audibility of harmonic and IM distortion, but, unfortunately, this contradicts the common experience of a great many people. It does so even when one admits imagined differences. My small club of audio buddies only acknowledge differences in amplification when it hits us on our heads, just like speakers can and do. You are, to me, a tantalizing paradox, because you are a very intelligent person who has succumbed to a personal need for definitive results. Science always benefits when the investigator is detached from the result. It always suffers from personal involvement. A good scientist serves the principal, not the end. Or, as Jobs says, "The journey is the reward." I make a lot of noise about this, because the finer points of hifi are on the verge of extinction. The endeavor is not immune to your influence. By promoting the idea that quality of reproduction is no longer a concern with commercial offerings, you do a disservice to the consumer, who is reliant on this very troubled industry. A possibility to consider is that your ABX design is adequate to the job, yet, in your investigations, you made other errors. I have written in a colorful style, to bring attention to the issue. Because you promote your device, or others like it as a standard, it requires scrutiny far above the norm. In another post, I mentioned that the NBS platinum bar is shrinking. No one expected that either. |

ScottW Answer the question, Scott: Two hard and nonparallel surfaces can have a maximum of how many contact points? Why are you changing the question, Bob? Anyway, it still depends on their shape.....and we're not talking diamond hard here so your inference that there is no conformance is just hogwash. Sander has given the correct answer. You simply didn't have the smarts to figure it out. Show us how spheres fall outside the set of shapes you specified. Show us how spheres can have 3 points of contact. and finally... show us why your assumption of perfect hardness is valid. ScottW |

Never said it was possible, what is possible is demonstrating whethere or not a given individual can hear them. If they can't then for that person, they don't exist. all you can say is that they don't exist under those certain test conditions, given that you have such test results for the given individual. My bet is that the vast majority of people who claim differences in sighted listening, which is the most unrelaible way to try and detect subtle differences, can't hear any in a blind, level matched, comparison. "If" that were the case, then you can say that they hear them sighted, but don't hear them under test conditions. The really interesting thing to see would be this: a) person hears differences sighted (According to you supposedly from expectation effects) b) person does not hear differences during DBT tests c) person is told of his negative test results (therefore removing supposed future expectation effects) d) person listens sighted again, now without expectation effects. Does he still hear differences, or did they go away with removal of the supposed expectation effects? |
