| A cable question, sort of... I would just coil it neatly. For power cables coiling is beneficial (as many turns as possible). | |
| A cable question, sort of... When you "coil" up the wire, you affectively create a parasitic inductorNo, you don't. You're not coiling the wire. You are coiling the cable (big difference). Look at the link at my previous post.In addition increase in reactive impedance, ev... | |

| Oscilloscopes - what specs to look for? Ground on a scope is normally chassis ground (on all except fully isolated). Careful when you connect ground both for potential for a short and noise you didn't expect.Even when scope is fully isolated there will be always some very small capacita... | |
| Why not underhung voice coil? @rodman99999 Thank you. As shorting ring they must work as short turn, reducing leakage flux. | |
| Why not underhung voice coil? @audiokinesis Thank you. I can understand it better now. I will try to find out more on Faraday rings. AFAIK they are used to lower influence of magnetic field produced by the coil, but I have no idea what they look like. I cannot find any pi... | |
| Would a wireless volume knob for home theaters be worth it? I cannot imagine big knob on my remote control, so perhaps either small knob or a slider. Buttons on my remote have just right authority/speed and anything else would be just strange (unnecessary). On the other hand I enjoy knob on my DAC/Preamp... | |
| Oscilloscopes - what specs to look for? @jaytor , I noticed that Siglent SDS1202X-E, sold and shipped by Amazon for $359 is identical to LeCroy T3DSO1102 sold for $725.I read that LeCroy relabels Siglent scopes. That would suggest that Siglent is a quality brand. Perhaps one day I wil... | |
| Oscilloscopes - what specs to look for? eyrepm, As Eric said 20MHz is an overkill for audio, but I would buy scope for any possible future adventure in electronics. The basic decision is how much you’re willing to pay. You can buy unknown brand for 30% of the established brand. What you... | |
| Group Challenge - Home lighting, who is in? Erik, perhaps later hour would be better? I know that radio stations have to reduce output power at night, per FCC regulation (better propagation at night), around 6PM. It can be even 7PM or 8PM, taking into consideration time zones and daylight... | |
| Coiling excess Speaker cable, is this a problem? Thank you Al. I just tried to explain why, knowing it is against common belief. | |
| Coiling excess Speaker cable, is this a problem? Inductance of a single straight wire is already reduced in the cable by bringing return wire close (cancelling magnetic fields). Twisting wires in the cable together reduces inductance even further. Coiling speaker cable will do very little to c... | |
| Do speaker enclosures need furniture polish or oil? Spraying Pledge Furniture (wax) on my black gloss piano finish speakers helped to reduce fingerprint problem. | |
| Coiling excess Speaker cable, is this a problem? Coiling would have negative effect for single wire, by adding inductance. Coiling cable is different - it creates common mode choke that has inductance only for common mode signals. For normal mode (differential) signals current in both conducto... | |
