Best means of isolating digital equipment i.e. DACs, CD transports, wall warts etc.

@jc4659 - the best way I have found to isolate components of any kind is to ensure they are NOT plugged into receptacles that are "daisy chained" together in a parallel configuration.

The daisy chained approach is often used in many power strips and power conditioners - so I avoid using them

I have one outlet providing power to my entire system...

• connected to that outlet is an extension lead with a single dual outlet on the other end
• into that is connected my amp and a second power distribution box
• each outlet in the distribution box is linked via it’s own pieces of wire to common neutral and live connection points
• that, in effect, connects each device directly back to the wall outlet
• so it is as though each device is plugged into it’s own wall outlet

This seems to eliminate any noise pollution issue in my system.

I also use very good power cables that eliminate cable generated noise, so the background of my system is extremely quiet.

@williewonka Thanks for the details.  What power cables are you using?

@tomic601 I did that swap and and my system sounds more clear with the analog going into the hydra.  A few years ago, different equipment and different room, the best I obtained was when the preamp was plugged into the iso tranny by itself with the digital feeding the hydra so totally opposite to how I have it set up now.  You would think having an isolation transformer at the front of everything would be ideal.  Once I have a dedicated line installed with outlets closer to my equipment I will be more judicious about using anything other than the cords themselves initially, then systematically try the conditioner and iso tranny.
@williewonka I would think that your power cords are making more of a difference than avoiding the daisy chain since they are all tied together at the wall but I'm not an EE.

I might have agreed with your statement IF I had implemented everything at the same time, but I developed my distribution box long before I got into building power cables. The distribution box proved beneficial immediately using the stock power cables that came with the components.

@cal3713 - I started by building my own cables using Bulk cable from companies like Furutech and DH Labs, but now I build my own cables - see this link

If you are not into DIY I would recommend power cables from KLE Innovations or Nordost.

Hope that helps - Steve

@williewonka Thanks for the details, they look great.
