Lacee,
OK - that is helpful. I get what you are trying to say, but still think the "Wall Plugger" concept as you articulate it doesn't exactly fit to world of audiophile AC management.
1. Direct "wall plugging" is not necessarily a low tech or "anti-audiophile" approach if your electricity is fairly clean at the outlet. Many HiFi enthusiasts purposely bypass very expensive conditioners for some or all of their gear because they think it sounds more "alive" and "detailed" at the possible expense of some smoothness and slightly "noiser" signal. In the extreme this may mean drawing juice through high end circuit breakers, cryo-treated 10 gauge Teflon coated Romex wire in the wall to cryo-treated Rhodium outlets... but "wall plugging" never-the-less.
2. In addition to cleaning up unacceptably noisy AC, a GOOD power conditioner's best purpose may be to protect your other gear from polluted AC coming from your digital sources instead of from the wall or the room. Cheap "power conditioners" typically add or subtract more than they should by clipping transient peaks and limiting musical dynamics.
3. Better power cords may act as "filters" to some small degree, altering or organizing current as it passes from the wall or conditioner to your gear. But their main purposes are to both reject EMF/RFI from the room and your gear from affecting the AC traveling in your power cord, and (most importantly) contain EMF/RFI around your high current AC cables from affecting low current signals coursing through the circuits in your electronics and interconnects. Whether plugged into the wall or your power conditioner, the major benefits to system sound resulting from better designed power cords would be the same.
So there are several kinds of "Wall Pluggers" - "audio-neo-phile-ytes", who don't think about AC until they blow a fuse, audiophiles who know about and actively reject all forms of AC management as so much fairy dust, and audiophiles who heavily manage AC but reject power conditioners for some or any applications.
There are at least two kinds of "Non-Wall Pluggers" - "audio-neo-phile-ytes", who believe power management is achieved by using power conditioners they bought from a rack at Best Buy, and Audiophiles who have thousands invested in AC management, including complex and expensive power conditioners.
So I think the real difference you are trying to identify is between the "AC Tweakers" and the "Stock Corders", not "Wall Pluggers" and "Non-Wall Pluggers".
