Robert, Do you have a clue as to what these guys mean when then mean "small signal" ? Solar flares probably disrupt their measurements... do you have a problem with solar flares adversely affecting your hi-fi? When Middius farts... you may be experiencing power ripple for days. George...try to contain yourself as Robert is contemplating his hi-fi performance, and don't even think about lighting one off again...poor Robert will be toast. His relays will oscillate indefinitely. ScottW |

When the contact is closed there is a damped oscillation with a frequency of between 2 and 3kHz, corresponding to the inherent resonant frequency of the tongues. "However a typical level for standard contacts can be extremely significant on very low-level signal switching circuits." Once again, Arny and his amphibian sidekick are caught in the quagmire of unscientific thought and sloppy design. The unscientific thought here would be assuming that if something could happen (which is all the article says) it did happen and adversely affected the performance of the equipment. The article says: "A further noise variable that can..." "However a typical level for standard contacts can..." And it also says that: "When the contact is closed there is a damped oscillation with a frequency of between 2 and 3kHz..." The potential logical problem with the word "can" is illustated by the following true statement: "At almost any time a car's tire can spontaneously deflate rapidly ("Blown tire") and throw the car out of control." This is of course a true statement. However tires don't blow and cars don't out of control every time we drive them. These days blown tires are rare. Just because something can happen, doesn't mean that it always happens. So, as usual Robert Morien is using bad logic to attack the ABX RM-2 Compartor which I partially designed. His bad logic involves trating an article about things that can happen, as if it describes something that always happen.s Why the indicated problem did not impact the ABX RM-2 comparator is hinted at in the article Robvert citted. That article says: "When the contact is closed there is a damped oscillation with a frequency of between 2 and 3kHz..." In response to one of Robert's earlier attacks, I pointed out that in accordance with Clark's JAES article about the ABX comparator (which Robert should be familiar with) each switch-over involved a complex sequence of contact openings and closings. Had Robert actually done his homework and become familiar with the AES ABX article he would know the details of those contact openings and closings. It trurns out that the last step of the complex series of relay contact openings and closing was in fact a set of contacts opening. Therefore, problems with contacts closing were obviated by the fact that thoughout the witchover operation there was always one critical set of relay contacts that had been closed for quite some time, that shorted out any and all signals whether internal or external, and that opened, not closed during the last step in the operation. |

Is there anything you CAN prove? I mean aside from the fact that you are an idiot. IN FULL: ---------------------------------------------------------------------------- ----------------------------------------------------- The choice of an electromechanical relay to be included in a low-level signal circuit can be a crucial factor in determining the levels of electrical noise within an application. In basic terms, the electromechanical relay is a comparatively simple component and when included in an application, it is somewhat governed by its inherent operating characteristics. When small DC or AC voltages are switched with electromechanical relays, noise can be generated, causing possible corruption of the signals to be switched due to heating and material effects. Specific constructional techniques during the circuit design, along with a careful selection of materials by manufacturers, can be employed in order for such noise generation to be significantly lowered, if not completely eliminated. Electrical noise levels occur because of the unavoidability of transition points between materials along the paths travelled by the signal. The transition points are always a compromise between the practicalities of the relay design, compared against an ideal electrical characteristic. This is due to manufacturing requirements that dictate that the metal connections are routed into the interior of the relay via sealed or moulded glass entry points moulded into the metal casing. To prevent mechanical stress between the glass insulation and the PIN passing through it when the temperature changes, the coefficients of thermal expansion of the two materials must be matched. Unfortunately, this results in the use of contact materials that produce noise voltages if heated. The effective temperature differences largely depend on temperature distribution within the relay and thereby on the relay construction and the geometry of the connections. Moreover, the manufacturers' datasheets only very rarely give information on the thermo electromotive force of relays. |

Is there anything you CAN prove? I mean aside from the fact that you are an idiot. IN FULL: ---------------------------------------------------------------------------- ----------------------------------------------------- The choice of an electromechanical relay to be included in a low-level signal circuit can be a crucial factor in determining the levels of electrical noise within an application. In basic terms, the electromechanical relay is a comparatively simple component and when included in an application, it is somewhat governed by its inherent operating characteristics. When small DC or AC voltages are switched with electromechanical relays, noise can be generated, causing possible corruption of the signals to be switched due to heating and material effects. Specific constructional techniques during the circuit design, along with a careful selection of materials by manufacturers, can be employed in order for such noise generation to be significantly lowered, if not completely eliminated. Electrical noise levels occur because of the unavoidability of transition points between materials along the paths travelled by the signal. The transition points are always a compromise between the practicalities of the relay design, compared against an ideal electrical characteristic. This is due to manufacturing requirements that dictate that the metal connections are routed into the interior of the relay via sealed or moulded glass entry points moulded into the metal casing. To prevent mechanical stress between the glass insulation and the PIN passing through it when the temperature changes, the coefficients of thermal expansion of the two materials must be matched. Unfortunately, this results in the use of contact materials that produce noise voltages if heated. The effective temperature differences largely depend on temperature distribution within the relay and thereby on the relay construction and the geometry of the connections. Moreover, the manufacturers' datasheets only very rarely give information on the thermo electromotive force of relays. Desperation time for the audiophools, now they're forging posts in order to deceive. The simple facts are these: Wire is wire. Amplifiers contribute nothing to imaging, that's a funtion of teh recording and the speakers. ABX is the accepted standard for audio research into subtle differences. It is a simple matter thse days to build auio equipment that is sonically neutral, that is neither adds nor subtracts from the input signal. An ABX box does not mask any differences. Vinyl LP's are an iferior medium and have several orders of magnitude more distortion than CD's, which is not to say that there are not some really awfull sounding CD's. Global feedback is not something that makes amps inferior, but if to much is used it will affect the way an amp clips. Stereophile has some of the most incredibly idiotic and hearing impaired reviewers on the planet working for them and they frequently endorse snake oil. |
