How to get my power cord priorities right system wise

While I totally agree with the posts made by the three very knowledgable audiophiles posted above my post I'm going to mention what I've experienced with several of my systems. This is the order that I found to work best for me, your mileage will obviously vary.
Conditioner
Dac
Transport
Preamp
Amp
The reason I like that order is that I did exactly what was described above, moving one high-end power cord from one component to another and the order I listed gave me the most notable improvement. There are way too many variables to explain why.

Thanks all for your input. 

Just to clarify, I do have the Isotek Evo3 Syncro II from wall outlet to a Isotek Aquarius Evo 3 conditioner and then components connected from there.
Started with one Isotek EVO3 Elite PC and found most notable improvement when connected between conditioner and Pre/DAC!

Continued with yet another Isotek PC at hand and found most notable improvement when connected between conditioner and CD/SACD!

Have now 3 high-end PC's in the system.

So, here's my findings so far (in ordet of notable improvements);
1) PC from wall outlet to conditioner - Isotek Evo3 Syncro II
2) PC from conditioner to Pre/DAC - Isotek EVO3 Elite
3) PC from conditioner to CD/SACD - Isotek EVO3 Premiere

Cheers,
Martin

New power cables get these inexpensive ends added and then put inline with any of three power distribution devices supplying 24/7 current to the TV/Audio systems.  They stay for a month minimum before finding their way into the audio system.  I tend to agree with others above and usually begin the trial with sources and pre amp first then onto power amp.

I agree, try them everywhere, but note that some are designed for digital and might have advantage there. I've noticed that gauge matters even for low power components, especially for dynamics. Are you using a preamp? I'm not, and have found dynamics to be very important i.e. more is better to make up for the missing gain stage.

I'm currently using Cardas Clear on amp and SR Atmosphere level3 digital on DAC. Those tuning bullets really do work and add flexibility to tune the sound. Don't forget the wall outlet! SR just came out with new and improved Orange fuses, I wonder if Orange outlets are next. I have Furutech GTX-R now. I wouldn't bother with an expensive PC for your sub, just play with some midpriced ones.

Edit, Paradigm reached out and said Personas do have Grills as a special build option for a little extra.
