Nordost Thor &State of the ART: Power conditioners

Have not tried the Thor but I would recommend you consider the line put out by Sound Applications. I tried a few and the moment that one went in my system, my search was done. I know another line to look up is another choice to consider. but give it at least a check out and go from there

Owl, what makes you think that the PLC can fix that problem? Just curious. Because with power conditioners you usually get improved imaging, focusing and soundstaging. Tighter bass and less grain on vocals. All results of a lowered noise floor. PLC will most likely not cure the sibilance. Not to a degree you are looking for. What are the components in your system? May be if you list them, you would get a valuable advise on what can be looked at to address this problem properly. Just my opinion.

Update: Tried the outstanding Oyaide AC outlets and it fixed the problem, BIG time to my shocked surprise. I'm not swapping these out for anything. I got the GX and XXX models and settled on the GX (gold over gold) for my EMM's stack. Things are crazy good now! The only problem I have now is trying to get some sleep. I may still look into conditioners as I like what they do with dimensionality and staging. AC is a funny thing and I think much underemphasized component of the reproduction chain. Amazing.

That's great. I was planning on trying these Oyaide outlets as well. As far as PLCs go, I really like Shunyata Hydra2. It's got only 2 outlets in the back and you can separate digital and analog this way. These things definitely work. And they are reasonably priced.
