Direct lines and adding a power conditioner


I have 5 direct lines with audiophile receptacles - Maestro, Oyaide R1 and Teslaplex. The direct lines come from a secondary electrical panel on the other side of the wall as the receptacles, so the 10 gauge romex wire is only a few feet long for each run.
I have tried a couple of power conditioners between the direct lines and equipment, but they have suppressed the dynamics. I was wondering has anyone used any type of power conditioner that would help the articulation and naturalness of the sound without any negative effects to the overall presentation?
thanks.

@ Jwpstayman, Hi, If you have a dedicated circuit breaker box with this scheme, It meets code nation wide!, This scheme drops the noise floor hugely in any circumstance no matter where you live or what grade of power you get from the power company!, Done right, all breakers work as designed!
Audiolabyrinth - not to belabor the point, but if you check the electrical code for residences, ALL circuits must have a single point of ground, which is the panel ground at the service entrance.
Jwpstayman, that is not true if you have a dedicated breaker box just for your audio recepticles, I can also add, there is no federal code!, what might not be code in your state, does not mean its not code in my state of alabama!, my set-up has been approved!, thus no need for some over priced multi-thousands of dollars line conditioner!, I will also add, It is very cheap to have an in wall surge protector for the lower power componets, LOL!, there is no sure protection that can handle a Krell 700cx amp!, I unplug the amp when It is not being listened to, thats the best cheapest protection,LOL!
