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.

@clearthinker those pre and phono amps used batteries build into the units or connected to a DC power inlet. That is different from using a cheap AC inverter running from batteries. I could word that differently. A cheap, high powered switch mode power supply.

The conversation has degraded to burning in AC power outlets. I think we have lost the plot on the conversation already. The op has not even verified there is a problem yet, but everyone is rushing to solve it without even knowing if there is a problem, or what it is.

This is what the inside of one of those low cost inverters looks like:  http://www.kerrywong.com/2017/10/01/teardown-and-testing-of-an-800w-puresine-inverter/  It is a high frequency switch mode power supply that generates the high voltage (~170V) and then a PWM stage, and then a filter. I don't see a lot of capacitors or filtering on the DC side, so there could be RF coming out. I don't see any FCC on most of these. YMMV

Old school ones with the big huge transformers are probably not as noisy.

 

I have battery storage device I tried on various components, prefer sound from dedicated lines and transformer based power conditioner. The cheap inverters in these devices is the problem, create their own noise/distortions. I assume those built specifically for audio, like the Stromtank have paid much attention to inverter produced noise.

It is this kind of audiophile sh-t that drives me nuts. All you have to do is buy equipment that has audiophile nut proof power supplies and you do not have to worry about anything except maybe lightening storms.

As for running components with battery supplies. I had NEW (Nirvana Electronic Works) DCA66 class a ss amp way back in 90's, early 2000's, ran off four wheelchair batteries, also have Merlin VSM-MM which has BAM that runs off 4 9V batteries.

 

Point is technology and implementation has been around for some time. Is it game changer? Based on my experience, no, and wouldn't you think audio manufacturers would have caught onto this if it was. Perhaps more battery storage devices with audiophile quality inverters will come to market in coming years, we'll see.
