Best kept secret in AC line filtering conditioning

I tried a number of power conditioners.....they all had issues I couldn't live with.   Im using Furutech carbon fiber plugs on Acrolink cable  right into the wall. Carbon Fiber face plates.....Maestro plugs.   seems good to me.

If I may ask, what were the issues with your power conditioners.

After watching a Caelin Gabriel video, I began to question having any surge suppression at the component rack. My issue with the Richard Gray’s 1200 I had was that it had sacrificial MOV’s and you would never know at what state the MOV’s were at.

Also, MOV’s can limit the peak current as the MOV’s don’t know whether a peak current is for musical needs or a current spike. So I believe the MOV’s were a bit of a current limiter.

So I made the decision to pull out the Gray, have an electrician install a Seimens FS140 whole house surge suppressor at the breaker box and get a power conditioner wit no surge suppression that does not limit current. The FS140 can surge suppress up to 140,000 amps. The Puritan? 9,000 amps. Plus the possible current limiting.
The PI Audio UberBuss has unlimited current abilities which I read is 40+ amps. It has a power factor correction of 1 which is very good. I don’t see any other power conditioner that even mentions the power factor correction of their conditioners.
The UberBuss has a non metal box to eliminate Eddy currents and has independant outlets.

It is considerably less expensive, and I feel superior to, the 156 so the UB was an easy decision.

The Puritan does not limit current. This has been my actual experience with large SS, pure class A amps which are very high current designs.  

Ok. Good to know.

I am under the impression that MOV's are a net negative to the current. Maybe in a minor way, but still are.

I'm not saying that Caelin Gabriel is 100% right about everything but that was part of his rationale for keeping surge suppression away from the component room. Maybe adds slight noise?

But even if we get away from that, 9000A surge suppression doesn't seem like much when you can get 140,000A protection from a Seimens FS140.

Direct lightning strikes are 5,000A-50,000A but can get up to 100,000A+. I live in S. Fl and have had close lightning but thankfully never a strike.

Class A amps have a relatively constant current draw, so series-mode filters (inductors) do not pose a problem.The dynamic (changing) current demand of Class A/B amps, however, is a problem. Inductors oppose changes in current flow which results in "current-starving" of the amp.
