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.

I have 2 dedicated 20 amp 14ga copper lines to my audio equipment.  Transparent Audio power conditioning, Furutech duplex outlets in our new home. A giant difference to me.

My electrical contractor also paid attention to the number of motors on the circuit and box and don't underestimate the value a good ground. BIG FACTOR.

Those are my experiences FWIW

 

@lowrider57   I think the grounding issue has assumed a life of its own, per the above comments.  I used 1/2 or 5/8 solid copper pipe (not an iron/copper grounding rod., 6 feet long. We drilled straight down, hammered the rod in and then filled the hole with a high-clay content soil. Was told this clay compound would help with grounding and conductivity. I was skeptical, but for the additional $15, I wasn't going to argue that point.  

My point really is there are many factors to consider with stable, clean power to the audio room. I didn't want to inadvertently omit one thing that might render all the other work wasted.  And as pointed out, we are still at the mercy of the grid.
