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


Is it better to route these digital noise polluters through a conditioner, isolation transformer or both in series?  Is a "digital" power cord sufficient by itself or could it be used with any of the above without negative side effects?  There are a lot of anecdotal observations in many old threads.  Can anyone help clarify based on what they have found?  I'm getting ready to add a dedicated circuit for my audio system and will be reconfiguring power cable connections.

@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
