Power Supply Quirks

I am continually amazed at how sound and performance of individual components are affected by interactions of their power supply.I found that where you plug in each component makes ALL the difference.
I was plagued by a recurring problem with my CD player, where the circuits would suddenly quit and put out loud noise.I had to reset it by unplugging. After trying every grounding trick to no avail,I finally cured it by separating the power supply to the tube buffer in my system, from the digital section of my Equi=Tech. It also smoothed out the sound of my CD's significantly.
The lesson there is that the digital power supply must be uncontaminated. I'm sure this is true for all front-end components.With a few other plug-in changes and some passive noise eliminators, I am amazed at the sound improvement. I kick myself for not thinking of this a few years ago.

Re: Power Supply Quirks

Instead of kicking yourself, we should be kicking the equipment manufacturers for not properly designing their power supplies and their input filters.

All digital equipment generate noise and what you should do is to prevent this noise from getting into the power supply of other components via the digital equipment's power cord. Many power conditioners have sections to isolate digital and analog equipment for this reason.

Re: Power Supply Quirks

I use the JPS Digital AC power cord, and my Equi=tech does have an isolated digital section. As soon as I replugged the buffer power supply into the analog section, the problem disappeared.
I posted my experience to alert others who might be contaminating their digital power supply and degrading their sound. I can only imagine how many audiophiles just plug everything into one circuit.
