best power conditioners under 4k

The best power conditioner we know of isn't a power conditioner. At least not in the normal sense of the word. It doesn't filter. It unfilters.

Hey millercarbon you forgot to supply a link to your virtual system.  I'm sure there's one or two posters who haven't seen it yet.  

Sorry. Didn't think it was relevant seeing as mine is custom but good point, OP may not have seen it yet. Here ya go.

OP,

Look into QRT products from Nordost, start with QB8. With their modular approach, you can start building SOTA AC distribution for your audio system. 

OP only thinks he needs a power conditioner.  In reality we've all learned that he really just needs a smattering of inexpensive tweaks from SR and others.  In fact ....anyone who thinks they need any new piece of gear should really focus on tweaks.  In the bigger scheme of things a $150 fuse is really going to make a more meaningful sonic improvement over a new amp, source or speakers....let's just be clear on this up front.  If you are in any way shape or form basically pleased with your system, DO NOT even think about upgrading equipment when you can tweak your way to sonic bliss.
