Phil,

Getting a dedicated line doesn't isolate your gear from anything, in fact one could argue that it makes it easier to couple the noise to your system.  I certainly wouldn't agree that a dedicated line had the same affect as the "Felicia" on my system.  It did provide a nice benefit, but nothing substantial IMO.  If you had your system on the same circuit as your fridge or microwave then yeah it probably did help a lot, mine wasn't.

Dejan,

Great to see you back around here my man!  BTW, the "Felicia" project outlined in the lab is a direct inspiration from having read your notes on filtering.  I pestered Occam (Paul) enough until he had me build and test some of his ideas.

Josh,

The non-dedicated line in my living room only had the 3 outlets in that room, plus the ceiling lights.  The dedicated line is, obviously, dedicated with nothing else on it.  And the voltage swings I see are noticeably less.  Are you saying that the dedicated line did not isolate my system from the other outlets/lights in my room?  Yes, I understand that they all share ground at the breaker box.

(I'll also note in my system that the break box and my listening room are on exact opposite sides of the house, so the line is very long (80ft+)...

No, I am not saying that. I'll forward you the paper by Dejan if I can find it easier.  It is straight forward to read, not super technical.  He raises some well known and except ideas on why noise gets into your AC in the first place and why dedicated lines won't fix it.  

Basically the line coming into your house is polluted because it is part of the grid of all of the US.  Everyone's hairdryer, microwave, AC, fridge, etc pollutes it, so your own fridge, etc are only a tiny fraction of the problem.  Dedicated lines only provide a more direct (less serial resistance) path for the external (if you will) noise to your system.  So you still must deal with it, but your Audience it seems does a damn fine job!

[Edit] This thread is now unlocked. Hopefully the message is clear this time. My apologies for interrupting the discussion
