Dedicated 20 amp circuit - Electrician laughed!


I brought my electrician out to my house today to show him where I would like to install a dedicated 20a circuit for my system.  He laughed and said that's the stupidest thing he's heard and laughs when people talk about it.  It said, if you're going to do it, you have to have it separately grounded (shoving a new 8 foot rod into the ground) but even then, he sees no way there can be an audible improvement.

Now, he's not just an electrician though. He rebuilds tube amps on the side and tears apart amps and such all the time so he's quite well versed in audio electronics and how they operate.

He basically said anyone who thinks they hear a difference is fooling themselves.  

Personally, I'm still not sure, I'm no engineer, my room's not perfect, and I can't spend hours on end critical listening...  But, he does kinda pull me farther to the "snake oil" side and the "suggestive hearing" side (aka, you hear an improvement because you want to hear it).

I'm not taking a side here but I thought it was interesting how definitive he was that this not only WILL not make a difference but ALMOST CANNOT make a difference.

millercarbon, your system is sick to say the least. Mind if I ask about your background or career? What allowed you to get so ingenius with the advanced and quite expensive tweaks??

Thanks. Appreciate the compliment. And the question.

The first book I remember reading, not counting the Encyclopedia Britannica (never quite read all of that) was Red Giants and White Dwarfs by NASA scientist Robert Jastrow. Since I had started with the Encyclopedia and since A is for Atom, etc, it was fascinating to learn where stars came from, how they formed and how mass is destiny. Stars fuse hydrogen into helium releasing energy and the rate at which this happens, how long it lasts, and what happens in the end is all determined by the initial mass of the star. https://www.amazon.com/Red-Giants-White-Dwarfs-Third/dp/0393850048 The school library had just gotten it in, it was 1969, and so I would have been 12 years old.

The next year I built a 6" reflecting telescope and started hanging around with Al George and the Tacoma Astronomical Society. Around this time I was riding my bicycle to Radio Shack listening to everything and learning about audio. By Jr high I had a pretty good stereo and a room with DIY acoustic panels and some time in high school built a Dynaco ST400 amp.

After college I built Roger Sanders ESL/transmission line speakers from his design in Speaker Builder. This was 1980. Then around the 90's, prime of life and with good income came a pretty decent period of time in which I went from tournament racquetballer to USCF Cat 3 criterium racer and RAMROD rider to accomplished marine aquarist, Porsche Club President and Driving Instructor, and builder/remodeler. That last part included designing and building my current listening room.  

The listening room was my dream of a lifetime. Originally sucked into all the same vortex as everyone else I wanted a 5.1 HT system and so the room was designed around that. Only when I went shopping and listening turned out HT stuff is all crap. Absolute dreck. Not that I didn't try. Put a good couple years into the effort.

Then came Stewart Marcantoni, the best dealer I ever met. I took Stewart in when he first moved out here to the PNW and introduced him to the area. Stewart took me in and mentored me in high end audio. Thanks to Stewart I was able to experience more outstanding gear than most guys can ever dream of, and was introduced to Ted Denney (Synergistic), Caelin Gabriel (Shunyata), and was even able to attend CES as a vendor one year. I knew DJ Casser and was the Washington State dealer for Black Diamond Racing for several years. More or less obsessed with audio I demo'd BDR Cones in probably 50 to 100 different peoples systems, and auditioned systems at just about every decent stereo store along the I5 corridor from Portland to north of Seattle.

All during this time thanks to my extensive and wide ranging background in science and technology it was easy to separate the wheat from the chaff and the science from the bull. Or so I thought. Sometimes the scientific explanation really does make sense and work. But then again often times not. Stewart helped me greatly in this. Time and again he would play me some insanely good sounding cable and I would ask how in the world? And he would reply very blase, "Oh he puts some dust or something in there, I don't know..." Which honestly one time was true- Caelin really did put some dust inside a conditioner! I have a bag of it at home still!

So that is my experience, Cliff Notes version. All I care about is the sound- and since I'm not made of money, how to get the very best sound for the money. When I say in my System description that its based on the philosophy that everything matters and no one component matters more than any other, that's not hyperbole or cliche. I mean every word of it. Only my understanding of what is a component drills down to every diode, cap and inch of wire.

Dont waste your breath here too much.  Too many know it alls but very few real engineers.  Cheers!!
Hi Dtx

I had a dedicated line with 14 AWG wire that I recently upgraded with a 8 AWG line and noticed very positive differences.  I followed the advice of Vince Galbo of MSB (see the article here: https://www.msbtechnology.com/faq/how-to-wire-your-house-for-good-power/).  He seems to know what he is talking about. I was using  a Synergistic Research PC 12 SE conditioner and an Active Ground Block SE and still was able to improve on the sound.  His article is very comprehensive and I can confirm his findings.  The only thing I did differently is using Perfect Path Technology Total Contact instead of his recommended Silver Paste.  Hope that helps.
