  • Dedicated AC Line vs. Choice of Receptacle

    So the biggest downside of moving to our new apartment (other than having to walk down 17 as opposed to two flights to the lobby) was the inability to install dedicated AC lines for my audio system. It looks like the electrical lines start at the breaker box in the entrance foyer and then are routed through the ceiling to the outlets in the different rooms. Sadly, there’s simply no way the building would allow the addition of new electrical lines and doing it without telling them (and them not knowing virtually impossible) would certainly give them grounds to terminate our lease.

    So I decided to instead go all out and change the receptacles to:

    Furutech GTX-DR NCF AC receptacles (latest version)
    Furutech GTX Wall Frames
    Furutech 06D NCF damped outlet cover

    Well all I can say is that so far I haven’t missed the dedicated lines and the system definitely sounds even quieter and more transparent than in the old place (course some may be speaker setup and room too). This shows up the most particularly in the back of the soundstage and how instruments pop out of the ether. So how much of the improvement when adding lines is the separate electrical lines vs changing the receptacle? After all anyone adding electrical lines installs new duplexes. Could audiophiles save money and just change their receptacles (that is something all should do if using what your home came with).

    So at this point I’m just letting the duplexes break in (I reckon they take around three weeks to settle in) and enjoying listening to the system.

    It seems you've answered your own question. If given the choice wouldn't you have run the dedicated lines?
    For me, it would be dedicated lines when given a choice.

    Here's the thing, you could change out any wall receptacle with a new receptacle which will grip the plug better because it's new and you will have made an improvement in your electrical connection.

        Ask any electrician or fire inspector what one of the leading causes of electrical failures is- poor mechanical connections.

        A good receptacle - not the 99cent Home Depot variety will make a world of difference because of good tension, proper materials and smooth surfaces. This is a good part of the equation.

        Most builder grade receptacles degrade from micro arcing over time and loose their tension because of poor materials. They should be changed in a home on a regular routine basis as maintenance. No one ever does it though.

        Adding a home run of wire to your audio equipment can be advantageous because you loose the multiple connections of other receptacles along the way with their bad connections. If you're force to share a line I would change the receptacles , light switches and tighten the Marr connectors + check the grounds on that line anyway. You will notice a difference.

        Good tight quality connections along the way are a great pathway to good sound and safety.

          A better option is to use an iRobot Roomba in an audio room. No plugging and unplugging.

          I think high-quality (1500 watts and above) hair dryers are the most power hungry home portable appliances

          I've seen the ceiling lights flicker on a 20amp circuit when turning on the hoover, they do suck a lot of juice upon initial switch on.

        We just had an extensive kitchen and living room remodel done. I did put in PSAudio receptacles for the home theater, but even the "standard" Leviton designer-grade outlets are far better quality (in terms of gripping the plug and quality of connection to house wiring) than what was common 20 years ago.
