Yes. The effect was a great palpability and suppleness to the music. I put it on the breaker, and both ends of the 10 guage wire connecting it to a Wattgate receptacle. It's still breaking in, though. Be careful, and always turn off the main breaker when working.
Isn't this going too far ?
People are gonna start applying contact enhancer to their listening chair legs to feel more bass....
Going to far ! Think about the air gap between the wire and the lug of the breaker. Yes it is ever so small, but the current has to jump from one to the other. Think of your current as a steady stream of water, or your current at the bottom of a waterfall, jumping, churning ect. I would pefer the steady stream as to preserve the current to the purest form from the start. Yes I understand what is being feed into my breaker box isn't to pure to start with, which is somewhat out of my control. But if I can improve, or preserve it to be its best, which is in my control, why not. Sometimes the little things make a big diffrents. Thanks, Brian
Than what's up with the Eichmann plugs and the new WTB RCA's. They go for a very small contact area.
BTW - I am not being antagonistic. I know nothing about this stuff and am curious.
Dave, as I understand the theory behind the Eichmann plugs and the new WTB RCAs, it's about reducing the amount of metal (and dielectric) in the connection more than reducing the contact area per se. There's a discussion of the design philosophy in a an article in Issue 71 of UHF Magazine
I haven't looked at your link yet, but how does that differ from what is being done by people using this stuff at the breaker box?
Is it because a lot of current can be asked for at the power connections whereas that is not the case for signal wires (spcifically ICs)?
I'm sorry, Dave. Your question lost me. The point of the small contact on the Eichmann and new WBT plugs is to reduce the amount of metal in the connectors, not simply reduce the surface area of the point of contact. It's the mass of metal they're trying to reduce, not the surface area per se.
As to using a contact enhancer, anytime there is a connection point, the electrical current has to make a jump across a physical junction: there will always be some amount of resistance and some amount of interference. Lloyd Walker talks about this from his experience with fine tuning control systems in nuclear power plants and chemical plants: wherever there is a connection, you can see on a scope the spike of spurious energy created at that junction point. That spurious energy is going somewhere, often as some form of distortion feedback back into the system. The contact enhancer will help reduce that, whether at the low signal level of an interconnect, or the higher power level of a circuit breaker in your junction box. From an article about Lloyd by Srajan Ebaen published at EnjoyTheMusic.com:
"One of his standard test procedures of the day involved the use of time domain reflectometers to test the integrity of critical wiring, say to the core of a nuclear reactor. Despite super-expensive connectors in the $1-3K per range that make our audiophile WBT jewelry look like candy box treats, Walker recalls that each such juncture and connection still caused very obvious signal spikes and noise reflections on his test gear. This constituted but one of many hands-on insights that would later find expression in his audio design work even though not all phenomena in the industrial arena translate directly into ours." http://www.enjoythemusic.com/magazine/earwax/1201/
Thanks for the info. As I said, I don't know anything about this stuff and am curious.
Do you believe in the Nexgen and Eichmann theory?
FWIW - I used the Mapleshade contact enhancer (similar to SST) and found that it created more problems and a bigger mess than it was worth. After plugging and unplugging the ICs a couple of times, the paste ended up getting everywhere as well as holding any dirt it may have come in contact with. My result was noise due to a tiny contact on one of my RCAs. Very difficult to diagnose since it kept changing as I tried to narrow it down to a single component by changing interconnects and the paste kept exchanging itself with ICs and smearing on the RCA. Only a slight film of paste was used too. It took hours to diagnose, then hours to clean-up too.
But, maybe it would be good on the breaker...where I'll never have to see it again.
Hi Dave, I think the philosophy of reducing the amount of metal in a connector has some solid theoretical foundation (as best I can understand it since I'm just a lay person), and I think the theory is being substantiated in some applications (for example, 47Labs has been doing this in their designs for years).
As to the Mapleshade Silclear, I think you'd have a different and more positive experience with the Walker Audio SST and Extreme SST. It also is highly conductive so you have to be careful with it as well, but it does not migrate (even under high heat) and it dries to a soft texture rather than remaining a paste. This makes it much more resistent to going places you would never want it to travel. Some people have noted a concern about the dried SST flaking, so again there is still room for good caution. In my system, I found the Extreme SST to make such a significant positive improvement that I consider it a necessary part of my system setup, with all the appropriate considerations for use duly noted.
Rushton, I've applied the Extreme SST stuff to most of the IC's and power cords in my system since receiving it last week and have to agree with you. It is really startling the difference it has made. Eventually I will get around to putting on the pins of my tubes but that will take a while!
Thanks for the follow-up, Mem916. Glad to hear its making a positive difference for you. Keep in mind that the break in will be most rapid on those contacts that have a larger electrical flow (power cords and speaker cables) and will require longer on connections like phono cables and phono cartridge pins. On phono cartridge pins, allow for about 20-hours of break-in versus approx. 5-hours for speaker cables. Applying E-SST on tube pins (particularly phono stage tubes) was worth the effort here.
I use Lloyd's SST in my system and recently Lloyd sent me a bottle of his new Extreme SST at 2x the price. I must admit that in my system there was a sonic improvement with the most noticeable at the volume which seemed much louder. All in all a good product HOWEVER when I switched to the Extreme SST I truly could not appreciate any sonic difference
