Experience with power conditioners?


Recommended Posts

Quite right @fas42. If there is a problem, then use an engineered solution to overcome. 

 

The choice of a 'power conditioner' does not fully relate to how that device will work in an audio system. For one, the impedance drops like a stone, and the caps in power conditioners can create resonances that cause more problems. Caps are unforgiving as to filter harmonics unless they are tuned with the correct inductors, at worst they keep harmonics locked in the system.

To estimation of impact power conditioner, us need to learn primary goal - analog output of DAC: what power conditioner change there?

A single point power supply will give all the audio devices the same reference. This means reducing the risk of unequipotential grounds that causes further SCIN in the signal leads. 

Further the conditioner, and can be anything that provides a single source, still means leakage currents can travel to and fro via AC power.  

To stop these,  for USB anyway is to use isolation in the signal path, or super shielding, xlr cabling, and bonding cables.

By no means is there a method to isolate Dacs from AC power without severely creating a high impedance where we want everything common to the one source.

That depends on where you are, I guess. My friend Sergio lives in Rome. He says that his mains is very noisy and he uses a mains filter. Another audiophile friend, Geoff, lives in Silicon Valley these days , but he used to live in London, He said that his mains was very dirty (and I've seen letters to the editor in several British Hi-Fi rags ask what they could do about the dirty mains supply. Also, keep in mind that while British receptacles are very robust and three pronged, most of mainland Europe uses a rather flimsy, two round-pronged receptacle without a ground connection.

The schuko plug has an earth connection built in for many, many years now. It is also not flimsy unless your hands are like hammers?
