| Cable vs. Electronics: biggest bang for the buck In my experience, I have seen customers go two ways, depending on their components: In the first case, their components are accurate and have low-impedance output drivers, particularly the source CDP. In this case, cables with lower reactance (cap... | |
| Are Nordost really the Rolls Royce of cables? The Stereophile review found them a bit lean in the midrange as I recall. May have been their system, though. | |
| Is it worth it to buy the Cable Cooker? What cookers do folks have experience with?Which is the best value for the money? | |
| When to bi-wire? No, you cannot measure with an ohmmeter. The way to measure this is to put an audio sinewave generator through a small resistor and drive the speaker directly. Then measure the AC voltage drop across the resistor with an Oscope or true RMS voltmet... | |
| Cable directionality Here are some more tips for you, since I design wires for my company:1) interconnects should be low capacitance - this means spiraled pairs of small gauge wire that are spaced-away form each other. Use Teflon or air-filled dielectrics to separate ... | |
| Cable directionality Bigtee wrote: "As I said before, you have the positive half cycle and then the negative half cycle that "Flows" the opposite direction on the same wire."Correct, the current alternately flows in what I like to call the "forward" wire, but the inve... | |
| Cable directionality "Audioengr, So, lets take a 60HZ signal and run it down the "Signal carrying" wire. Since this would be the same as a 60hz sine wave, are you trying to say that the positive half cycle goes down one wire and the negative half cycle comes back on t... | |
| Cable directionality seandtaylor99 - I have also tried it and found no difference in my particular system. I believe that the results are very system-dependent. In systems with poor grounding, it could make a big difference in theory.BTW - I am also an EE with 26 year... | |
| Cable directionality Bigtree - Here is why your single-wire scenerio worked: The return current for the signal was running through the ground of the power cords of the two components. This is simply batteries and bilbs. The current flowing in the signal wire must retu... | |
| Cable directionality In general, the reason that the shield of a twinaxial cable is grounded at the source is because this is where the signal is being driven. The most accurate ground reference for a driver will be at the driver, not at the destination component. If ... | |
| Why do digital cables sound different? Sean - Transmission-line effects are the main concern with digital cables. Characteristic impedance matching is a big part of this. However, dispersion of the digital signal is also caused by dielectric absorption, which can cause jitter, so just ... | |
| Why do digital cables sound different? Jt25741 - You are dead-on when you say that jitter is the main issue with digital cables. However, with some cables, you get what you pay for. Every cable manufacturer has a digital cable and many of them are not even close to 75 ohms characterist... | |
| Why do digital cables sound different? Zilla - it is impossible for a digital cable to act as a "tone control". What happens is that the jitter caused by the cable losses results in frequency modulation of the analog signal. This can cause lack of clarity and focus. In general, the bet... | |
| DIY speaker: braid vs twist vs straight Twisting is usually a better performer because it locates the forwards and return wires in close proximity and creates some field cancellation. When the forward and return paths are in parallel or twisted, this lowers the inductance substantially ... | |
| Electrostatic speaker cables... Propagation speed????? You must be joking. This is not a common-clock digital system. This is analog audio for kripes sake! Series inductance is the most important parameter, followed by capacitance and dielectric absorption.If you need a low-indu... |
