In Reply to: RE: More hyperbolicness for Lew posted by Tweaker456 on May 26, 2017 at 12:21:48
I did accuse you of being hyperbolic in your rave review of the results.
In this case, do you really want to convince people by quoting advice from an "expert" who (1) does not apparently warn his audience to use only capacitors designed for use across an AC line, and (2) actually promotes a dangerous practice (which you point out, yourself)?
Follow Ups:
Yes to your question Lew. He hears what I and others hear, that larger value and better caps sound better across the AC. One can, as I'm sure you know, use way larger caps than .3 and still be safe. The question of safety and sound quality are two different things. It is also rather elementary to point out that a 10uf Type X safety cap will roll of more EMI than a .3uf. I have other peoples empirical experience. science and my own empirical experience on my side of what IMHO shouldn't be an argument. Please don't bother checking it out for yourself. I know it's a lot of work and expense. More EMI bad, less EMI good, farshtayn? I rest my case. Over and out on this issue. T666

But consider also that as you add capacitance, the impedance between the hot and neutral AC line at 60Hz, the mains frequency, will go down in direct proportion. I don't know what bad things might happen as Z gets extremely low, but it might be something you want to consider. For example, the Z of your 10uF capacitor at 60Hz is (only) 265 ohms. And of course, you REALLY don't want to use large value caps between hot and ground or neutral and ground, as I think you know.
Lew,you can call all the capacitor companies that make 10uf Type X EMI filtering capacitors for use across the ac line and explain to their engineers about how bad it is to use their product for what it has been tested and designed for. At least Bullethead is getting some Z's from my advice. Oh, and once again, don't take the yuge effort and expense to actually try this TWEAK. Just worry about Z's. Like why try to make your system sound better when you can nay say until the cows never come home? I'll gladly drop this subject when everyone else does. Hey doctor man, you got anything for a headache?? Tweaker456

In this case, I am only pointing out a potential safety consideration. You can do whatever you want in the privacy of your own home. I would wager that those 10uF, X-rated capacitors were not marketed with the thought that Harry Homeowner needs them for his audio system. And, I did not say the capacitors are inherently un-safe, nor do I think that; I did say that for your application, you might want to consider that there can be a safety issue. Z is an abbreviation symbol for Impedance, by the way.
I can't believe you actually came back! You should change your user name to LOSER456!!!

And what did I lose? I'm not losing out on the benefit of this excellent tweak. I must admit at this point that I have lost my youth. Tweekie

Tweeky's system by his own admission uses a Brick Wall Surge Suppressor, see https://www.brickwall.com/pages/how-it-works
This contains a large inductor. Most of us are not silly enough to add inductance to our power lines like this. Even fairly small inductors have a detrimental effect on SQ in my experience.
But this might explain why he needs these 10uF caps across the line, to try to take away some of the negative effects of the inductive line supply. Kludge upon kludge.
Yo Toxic, if by Tweeky you think you are talking about me you are mistaken. All I use is capacitors across the AC line. I have no brick wall filter and use no inductors. There is at least one other person with a similar name that you may have confused me with. And that's Tweaker456 to you!

> > > In my own DIY AC line filter, I use a Brick Wall surge suppressor ahead of all caps. Unlike MOV's, it will not deteriorate and fail over time at least that's the manufacturer's claim.

You are the same person right?
These were the comments by the person who wrote " The Great Capacitor Shootout" as stated in the Subject and previously discussed. So no, I am not the same person. If you somehow think that the brick wall filter he used before the cap test nullifies mine and others position I do have a suggestion. Try it out for yourself then come and tell me I'm full of crap. Then at least I could then come back and tell you that you are deaf. Game Bo? We could then both die happy. And another thing. I would say that that supports my position. The improved sound even after another filter according to him. Even after a so called brick wall. Looks like those EMIs are like cockroaches. I myself don't like those guys hanging around my ac. Just sayin'. T456

Hard to tell where your quoting ends and your ranting starts.
None of it was my "ranting". It was 100% from "The Great Cap Shootout" except my standard Borg message. So, I guess your last useful comment means that you are going to try it. Great. Let us know what a useless tweak it was. Am I in the Tweaker's Assylum or the Twilight Zone? Soon I think we are going to reach the Outer Limits of stupidity.
