| Why Expensive power Cables when Romex behind Wall? "I intend to purchase a couple of plates next time I visit Home Depot. Worse case I return them a few weeks later."I cannot believe that you guys are inventing your own "snake-oil". Best of luck.I have tried my best to actually do the science to p... | |
| Why Expensive power Cables when Romex behind Wall? "Shielding the cables as they near this big rack of electronics may make all the difference. Perhaps the worst dirt is the dirt generated by your own system feeding back into itself. This could explain why shielding may help."Sorry, but this is te... | |

Bwhite wrote:"Here are quotes from Audioengr's "Technical Papers" - seems he is contradicting himself in claiming that resonance is for the most part not audible"No contradiction. If you take the time to read the paper, you will see that I am talk... | |

Nikkidanjo wrote:"Basically, I don’t by the filter part unless some form of RF filter was deliberately added."Agree 100%, power cords should not be filters, particularly on power amps.The best analogy is that the pressure in the outlet of the pipe... | |
| Cable vs. Electronics: biggest bang for the buck Bwhite wrote:"So... then please explain how inserting a good cable into a system reveals the problems of the system as you have stated repeatedly. Its the chicken and the egg isn't it?"Answer: Hshapiro is 100% on the mark and I agree with him. It ... | |
| Opinions on this "white paper" The best way to determine whether a particular design is worth trying is to first compare the measurements, then audition a couple of candidates that measure well. This is necessary because some of the effects, such as dispersion will not show up ... | |
| Opinions on this "white paper" The measurements have been made - i have made them. The real challenge is to correlate these to audible affects. This has not been done by anyone ... yet.Interconnect cables have different phase shifts, different dielectric absorption, different c... | |
| Why Expensive power Cables when Romex behind Wall? Bwhite wrote:"Make sense?"Not to me. In fact, IMO mechanical resonances account for very little that is audible in most systems. Certainly if you put your components on a thin steel shelving unit, you might get some mechanical resonance effects, b... | |
| Why Expensive power Cables when Romex behind Wall? Outlet quality and contact resistance is at least as important as the inductance of the power cord itself. Silver-plated brass outlets can work wonders for dynamics and detail.Back to the question of the last 6 feet. Here are some calculations tha... | |
| Opinions on this "white paper" Their theory that electrical resonance can be a problem with electrostatics has merit. However, there is no proof that it is a significant problem or if so, is audible. They do not show how this resonance can result in "brightness". In general, th... | |
| Cable vs. Electronics: biggest bang for the buck Audioengr is there a difference in sound between Auricaps and Black Gate?Do not know. Probably dependent on the application. If there is, it is a difference in internal resistance or dielectric absorption. Neither affects "tone".Do Caddocks sound ... | |
| Cable vs. Electronics: biggest bang for the buck Bwhite wrote:"But.. what about the other modules?"Let me give some examples, since I have some technical knowledge in this area:1) Film resistors - these are lower inductance and lower noise. They reduce the thermal noise that causes the hiss at l... | |

| Cable vs. Electronics: biggest bang for the buck "Audioengr - you are totally overlooking the fact that each module in a component DOES add a sonic signature - maybe the gain and buffering stages do not but can you honestly say that two different analog output stages on CD players or two differe... | |
| Oxidation and bare silver or silver coated wire??? "Spade's Bannana's just get in the way of the music."I do not agree. If you crimp spade-lugs, you can get a lower resistance contact than with bare wire.As for silver oxidation, there is no anecdotal evidence that oxidized silver sounds worse than... |
