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

two lines are fine, i would swap the Hydra and the Transformer and see which sounds better.

on the post above, maybe...but first get your audio clean circuit off the dirty leg of the AC panel, that is the one with refrig compressor and motors.

also good to tighten your panel connections including grounds on a periodic basis - dont do any of the work i mentioned in this post if unqualified.

@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
