content: It is the whole web site like that. I guess the guy just making fun.Or may be not"Imagine a resistor that passes on the full dynamic range of the signal, while being completely transparent itself. Completely "invisible". That's Invisistor"

content: there is some value in it, even in good electronic (esp. for audio) commercial devices the larger electrolytes are glued or kitted together to prevent acoustical resonance. But to take it this far is a bit whacko IMO.

content: Quote from: ludzinc on October 13, 2014, 09:17:01 amI also find it a bit puzzling. You read about this on less scientific sites , esp audio sites and you can see inside expensive audio equipment strange mechanical contraptions around the large elco's, i have seen bitumen, lead and copper mechanical fasteners. Those can not be seen from the outside so just for optical effect is not the reason.I will not make a statement here that it exists on larger electrolytics since I would like to have some scientific proof but I do know it is a well documented phenomenon with ceramic capacitors1,2.1http://www.murata.com/en-global/products/capacitor/mlcc/solution/naki2http://www.edn.com/design/components-and-packaging/4364020/Reduce-acoustic-noise-from-capacitors

content: I like how we never even proposes any possible reasons for an improvement, other than a generic "companies are evil" jab. He's just like "Of COURSE its better, because its 'natural!'"Look at the size of the VNM and VMP caps! How could they NOT pick up a bunch of noise?

content: "The treble became brilliantly sparkling, with no trace of sibilance...""Sibilance" is a not very often used form of the word "sibilant" - making an "SH" sound or a "sssss" sound. So the mod removes the high frequency content of your audio so you can't hear the "sh" or "sss" in words? How can that be good?Or, is he throwing terms around at will without the bother of having to really express any real meaning?
