Who has dumped the power conditioner?

Timztunz, I think that you are right on about most power conditioners lacking headroom. It looks like the Silver Circle Power One 5 is just a very large transformer. I think that others, such as Synergistic Research have found more innovative methods to avoid constriction.

As dismissive as it is, the comment is, at the very least, uninformed. The pure power one 5.0 also contains a proprietary hand-built filter for eliminating common mode and differential mode noise and the finest electrical transmission components available anywhere. I would not be so quick to dismiss something in so quite an offhand manner until I had experienced it. It might be quite surprising.

Tbg should investigate and audition the Silver Circle Audio 5.0 power conditioner. If he did he would soon experience a lowered noise floor, increased dynamics, improved clarity due to better imaging and resolution and in general a bigger and more musical presentation.
My bass extension and increased dynamics were worth the price of the 5.0.
The other improvements realized were the icing on my cake.
This power conditioner simply out-performs every other conditioner on the market, period.

What is "skin"?

Skin, meaning the outer portion of a conductor. I used the word as it is used in the term "skin-effect".
