| 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... | |

| Measure power output without oscilloscope Power can be either peak or average. Relationship between them depends on the shape of the signal. For sinewaves average is a half of the peak power. Knowing peak power (peak voltage squared over speaker impedance) will let you calculate average p... | |
| Future of cables! Bigkidz, AFAIK toroidal transformers have very little magnetic flux leakage and perhaps are quieter under normal conditions, but lack of core gap makes them more sensitive to DC in mains, that can produce noise or even saturation. | |
| i'm having a problem with digital brick wall mastering It doesn't have to be compressed to sound distorted. Brick wall filtering might affect sound negatively but not by compressing the sound. | |
| Future of cables! Knot would introduce inductance for common mode signal and no inductance for normal mode (common mode choke), but I doubt that one turn would make any difference. I would rather put as many turns as possible on large toroidal ferrite core (with ... | |
| i'm having a problem with digital brick wall mastering Delay should not make any difference unless filter does something else to reduce peaks. At this point we don't know what this filter does, but if it works then use it. | |
| Miles Davis tonight on PBS! Fantastic. Even sound wasn't bad (for TV). | |
| i'm having a problem with digital brick wall mastering I'm not sure what you mean by "allpass filter". The function of "allpass filter" is to delay phase without affecting amplitude (flat frequency response). Clipping might be caused by intersample peaks/overs. They happen when filtering of the DAC'... | |
| Miles Davis tonight on PBS! Thanks, I will record it. | |
| Future of cables! You're right, It should be "outside of wire" (and not cable) or "in the space between wires". There is only magnetic and no electric field on the outside of the cable, so energy flux cannot be created there. | |
| Future of cables! You still haven’t explained why is it necessary to connect the copper or banana plug or whatever we use to the speaker since the cable doesn’t carry the energy but it’s carried outside the cable.Without this connection there will be no electric cu... | |
| Future of cables! djones51, I found very nice primer that explains step by step:https://www.researchgate.net/publication/255626544_Understanding_Electricity_and_Circuits_What_the_Text_Books_Don't_Tell_You |
