slwiser PE: -24db @ 60 Hz - 75 MHzPE II: -24db @ 60 Hz -50db @ 120 KHz - 1.5 GHz.....

Would you elaborate as to the test conditions, so your data actually has some meaning? What instruments did you use for the measurements?
Since the Power Enhancer plugs straight into the socket, it can be problematic plugging it in, if the socket is right in the corner, blocked by furniture or otherwise restricted.A good solution is to use a standard power cord into the socket, with a "PC burn-in adaptor", and plug the PE into that.http://www.vhaudio.com/acplugadapters.htmlHope this helps someone.
WOW,,, $2.59 each. They just don't come any cheaper that this, about 1/2 less than I paid. Nice find Alan. Cheers,Robin
I'm so impressed with the overall naturalness, wide soundstage and relaxing vocal ease that I went ahead and hardwired one Power Enhancer to the IEC inside my Cambridge Audio 840C CD player(making sure neutral and hot were wire correctly).
Quote from: Huck on 3 Dec 2007, 10:48 pmJust wondering if the PE's need to be "de-energized" when moving from one place (outlet) to the next?. Thanks, Huck Supposidly, yes but only as a safety precaution as the capactors store a charge that could cause a shock. I don't bother discharging them and I haven't had any problems but I'm also not going out of my way to touch both pins. If it's a concern, simply plug them into an unplugged power strip that has a lighted on/off switch being left on. The bulb will discharge anything there.Cheers,Robin

snip........ Some PLC manufactures roll capacitors in ERS, this is considered a big no no, all that does is roll off the natural ringing frequency of the capacitor. It is the ringing frequency that creates the crossover effect to naturally filter out noise in that particular frequency band. The same is true when transformers are wrapped and the phase is shifted by increased magnetic fields. Damping the frequency shifts the operational band of the part. All of these components are designed to work within a certain parameter, changing the frequency renders the part useless for it's original intention. The choke effect creates harmonic notches (peak and dip odd harmonic frequencies) all over the place and it's very difficult to bring the harmonic balance back. Basically once the frequency is shifted it's gone forever, all we can do is install tweaks as a band-aid and hope for the best. The PE can help by removing the stray inductance created by these magnetic products. As soon as the choke effect/inductance is removed the attached component will respond more efficiently. The amount of PE's required will depend on the level of damage that has been done to the odd harmonic frequencies.
