New Dedicated Line - Almost No improvement

Hello,

Newbie here and electrical idiot. Just moved to a new to us house in Tampa. Before we moved in I had an electrician put in a dedicated line (has it's own breaker switch) which is 10 gauge and two Furutech GTX-D outlets - Rhodium.

When I hooked up the EMI meter in my old house, which didn't have a dedicated line, the reading was usually around 26 or so IIRC. At the new house the outlets are 89 usually and the dedicated line is usually around 82 - so not much help for the cost of the "project" and pretty noisy.

Also, when the ac /hvac is running the meter reads about 100 points higher (!) for both the regular outlets and the dedicated Furutechs. Not good.

Thoughts? Does the dedicated line need it's own breaker box? 

I'm also considering a line conditioner but wanted to see what could be done here. Thanks.

So I keep trying to share around this and few people want to listen. :D

The heavy gauge and tight connections will reduce voltage drop but also puts you closer to all the noise. They don’t do a thing about that, whatever comes in, and even a great deal of house noise, stays in. The last thing I want really is a perfect conductor.  I don't know why people think the power that comes off the transformers is necessarily ideal... but nope, can't stop them.

But also please keep in mind those EMI meters are as far as I can tell no more than snake oil. No idea if the frequencies they measure have anything to do with hearing.

In any event what I can say is that I won’t plug anything I care about into a wall without Furman and LiFT and SMP. The SMP filters starting around 3kHz, which is a lot better than most EMI/RFI filters.
