| Why do digital cables sound different? Whether different digital cables sound different is very dependent on the DAC design. Digital cables will typically NOT drop bits. Any degradation has to do with jitter that is introduced due to the cable losses. DAC's that completely re-clock the... | |
| Longer speaker cables or phono cables? Even if you use low-capacitance interconnects, the longer speaker cable is still preferred. I did an extensive study of this. The results are independent of actual failure criteria, but I needed to choose an arbitrary one. The simulation results a... | |
| interconnect help How low is the capacitance on these "pro" interconnects? | |
| Energy, Environment & High End Audio Why dont you try a class-D switching amplifier, like those from Linn or Spectron? Thye burn very little power unless the signal is large. | |
| AC Power cords, which components 1st...? Definitely put a low-inductance cord directly to the wall outlet for your power amps first. Also, upgrade the outlet to a 15-amp with no steel in it - only brass. IF you want a really low-resistance connection, use the silver-plated Acme audio out... | |
| Why Expensive power Cables when Romex behind Wall? It's true that some components are designed to be invariant of the power-line voltage. Some Linn equipment is like this, particularly when switching power supplies are used. However, in most amps, the linear power supply is not even regulated, and... | |
| Why Expensive power Cables when Romex behind Wall? Even though the cord is short, it still contributes to the overall inductance. ROMEX has up to 10 times the inductance of good after market power cords. If the the last 6 feet of a 20 foot run to the panel is an after-market cord, it will add very... | |
| What's better: RCA or XLR? Depends on your components. The designs of balanced outputs can vary greatly.Balanced connections have two signals, a positive and a negative signal, which are inverted versions of each other. They carry the signal currents. At the destination, th... | |
| Do power cords really matter? There are certainly a class of cables that do have various types of filtering. However many just attempt to minimize resistance and inductance. These tend to be optimum for power amplifiers. | |
| How does length affect power cable sound quality? In systems like the power feed or amplifier feeds, the output impedance of the power source is very low. Because of this, the capacitance between the two conductors is not important. The series inductance is important because current transients th... |
