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.

Wow! I can certainly understand why you’re disappointed. One solution would be a system (conditioner/uninterrupted power supply) which employs a battery such that the AC for your system is generated from the battery’s DC power. Another item you might try is an isolation transformer which will cut down on a lot of the EMI, line noise and spikes/ surges just by virtue of its being a large inductor. Just some thoughts off the top of my head. I know such devices exist, but I can’t recommend specific products.

Good Luck, mean it.

The idea would be to run several dedicated lines one for each or similar pieces of equipment. Dedicate for digital and so on. 

No need for a dedicated box this just adds another break in the line.

Some have told me that stranded wire works best.

I am not a fan of conditioners or similar as they always, in my experience, took away as much as they gave. I do have very good power however.

need to look at your panel, you want if possible to have the dedicated line on the opposite LEG of the panel from motors; AC, Freezer, Fridge…. Start there….

Laynes, in my previous home, I had a 20 amp dedicated line for my 2.1 system amp and a 15 amp dedicated line for my front line equipment and surround amp. I used a Running springs audio power conditioner for the 2.1 amp. I recommend line conditioning. I also had upgraded, audiophile electrical sockets and upgraded power cables. It blackens your backgrounds. That was the main difference i heard. My audiophile pro recommended the Running Springs Audio because it does not limit the flow of electricity—it just corrects it as it flows through it. Many “power purifiers” tend to limit the flow of peak power, causing clipping of dynamics. So read up on HOW your line conditioner works. I would definitely not put two powerful amps on the same conditioner as well, even if it has two plugs, or 8 plugs or whatever.. And don’t put your frontline equipment on the same conditioner as your amp. My two cents, passed along from my trusted pro.
