| 192 from usb/spdif to NOS dac to amp Matt, the difference between traditional converter and sigma-delta is pretty much the same as the difference between CD and SACD. Instead of creating many discrete voltage levels, corresponding to input code, Sigma-Delta creates bitstream of varyi... | |
| Directional speaker cables - switching direction Al, link works if you remove last characters after "9".Their test proves what you just said - digital cable is not exactly symmetrical presenting slightly different characteristic impedance on both ends. This is very different from directional pro... | |
| How to protect my amp without changing the sound? Audiolabyrinth, I live in Chicago suburb. My part of the neighborhood has power lines underground. We have rarely any power disruption. | |
| Directional speaker cables - switching direction Electric current is a very slow flow of charges, while energy flows fastI'm not sure where you got it. Electric current is a flow of charge. Charge moves in the wire in speed close to speed of light. It has nothing to do with slow motion of electr... | |
| Directional speaker cables - switching direction As fate would have it the audio signal is not the current. The near light speed refers to the signal not current.Electric current is flow of electric charge, that moves near light speed in the wire. Electromagnetic wave on the outside of the cable... | |
| 192 from usb/spdif to NOS dac to amp If your D/A converter operates straight from 192kHz than it might get even worse since converter's THD is higher at 192kHz than 96kHz. My Benchmark DAC1 upsamples to very high frequency but then down-converts to drive DAC at only 110kHz (in spite ... | |
| How to protect my amp without changing the sound? No, I could not detect any difference with arrester. Furman with its tight, strong, non-sacrificial under/overvoltage protection and build in circuit breaker is probably enough but double protection sounds better. In addition I've already lost gar... | |
| Directional speaker cables - switching direction Jea48, I don't know if conductor can be directional but copper oxides are semiconductors. Their orientation might be related to grain orientation - a question for metallurgist.AFAIK dielectric affects speed of current. This speed is not a light sp... | |
| How to protect my amp without changing the sound? Audiolabyrinth, Furman doesn't change the sound or at least I cannot detect it (i don't listen very loud)/ If anything, bass got more even/musical. Strange thing is that TV plugged into video outlet got better colors, cleaner and more saturated. I... | |
| Directional speaker cables - switching direction So if energy flows in one direction, which direction does it flow?+ to - or - to + ?From source to load independently of polarity. | |
| How to protect my amp without changing the sound? Linear power supplies take current in narrow spikes of high amplitude. Any impedance in the path causes proportionally high voltage drop and the loss of dynamics. I use Furman Elite 20PFi and cannot tell the difference. Perhaps power factor correc... | |
| Would vinyl even be invented today? If I cover 3/4 of my 55" HDTV I will get even less pixels than my old Sony Triniton, but picture is still far, far superior. It is not amounts of dots but quality of the picture/process. HDTV uses the same amount of bandwidth as analog TV but deli... | |
| Do you always keep the Amplifier powered on My espresso is about 1500W for 20min (minimum to warmup machine) making 0.5kWh per day (for just one coffee) while my amp and the DAC take together 20W for 24hrs = 0.48kWh. Landscape lighting takes much more, not to mention driving SUV, watching p... | |

| Directional speaker cables - switching direction But power is delivered only one direction thru electromagnetic field. Who said anything about displacement of electrons? |
