More hyperbolicness for Lew

"A Do-it yourself approach to AC line filtering

This is only for the EXPERIENCED HOBBYIST who is familiar with a soldering iron and basic house electrical wiring practices. [Please note that Positive Feedback assumes no responsibility for injury, damage, or loss sustained by the DIYer — the reader proceeds AT HIS OR HER OWN RISK.] Inexpensive and simple AC filter adapters can be made using large-value metallized polypropylene film capacitors. There are no commercially available units equivalent to the designs suggested here. If correctly utilized, such hand-made plug-in filters have a huge, almost unbelievable effect in improving the sound of digital, an order of magnitude more than the commercially available units mentioned previously. Multiple plug-in capacitors are required for best performance improvement. About half of them should be connected from AC line to neutral, and the other half connected from neutral to earth ground. The more the total capacitance, the better the sound. The 120 VAC line to neutral capacitor adapters should of course be carefully insulated using tape and/or shrink tubing to thoroughly insulate the caps and wiring to the 2-prong plugs." This is a excerpt from "Recommended Audio System Tweaks Part 1" by David Magnan. No one should be using large caps from neutral to ground as it can be dangerous so he is wrong to be recommending that. This is more corroboration for the idea that large caps for an ac filter can be heard and well like as a easy, cheap tweak, safe when done properly. T456
