Shunyata acutally recommends more current draw in order that its PLC work properly. I have experience with the Hydra (8). Pluigging just the front end gear made little difference. It needed a larger amp plugged in in order to maximize the PLC.

Hello my friend: interesting what you comment about plugging more current draw into the Hydra so it works better. Now, regarding to plugging the amplifier into the Hydra, I respectfully disagree: the power amplifiers works better when plugged directly into the wall outlet (or equivalent), so bypassing any Power Line Conditioner, either the Hydra or any other p.l.c.; I have tried several times my McCormack DNA225 "Platinum Edition" into the Hydra and something is missing, specially clarity and "slam" and dynamic authority. When plugged directly into the outlet of the Richard Gray Power Company 240 Volts Sub Station it works much better, with more air and room to breathe. By the way, although the RGPC Sub Station is fed with 240 volts, it is actually a step down transformer and it has four Industrial 120 volts outlets. Best, Antonio Machado.
You are welcome to disagree. I am simply stating my experience. The Hydra has been the only PLC I use on my power amps. While I haven't tried them all, it has been the only unit which noticeably increases the detail and control. I do admit my unit had 200 hours on it, it took another 3 months of fairly continuous use for it to fully break in. I use a variety of amplifiers, including QS tube monoblocks, the smaller McCormick's, the CJ premier 350. It has performed well with all of the amps.
Again YMMV.Stu
PS. I use dedicated lines with premium duplex outlets and extensive PLC and RGPCs on my front end gear. I am, like you, a definite advocate of high current capability for all my power sources. In fact I rewire my RGPC with larger gauge wire for a nice improvement in sound quality.
The Q of a multipole filter is dependant on the effective load. Lightly loaded filters can actually peak and increase noise at a pole. Larger loads eliminate those peaks and increase the slople of filtering. I assume this is why Jon Risch suggests loading his filter with a incandesant lightbulb.A simple test would be to plug a lamp with a 100watt incandescant bulb into the conditioner. See if you subjectively prefer the filter's benefits with the light on or off.
My mistake. I believe the Shunyata conditioners are not multipole, but first order filters, simply caps accross the line, and hence not subject to Q peaking.
That's likely due to the large solid-core buss used inside. Low voltage and low current gear will *never* fully condition the buss....it's hardly getting stressed. Ergo, little "break-in", no matter how many months of use.
