Best kept secret in AC line filtering conditioning


How many of you guys truly know of Puritan Audio Labs ? Not many yet ,these are made in the U.K 
I have 3 friends in Europe that own them , and found a guy at our audio club just  an hour away 
I will check out next week , and against the much more costly AQ niagra  this removes hum,noise 
like nobodies business .model 136, and  better still model 156 all under $2k check out the video.

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.

"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."

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.
Both can.  I also used it on a A/B Coda #8 powerhouse amp.  No loss of dynamics. 
I don't know enough about electrical/electronic engineering to look at the inner workings of a unit and know what's going on there, but there are plenty of photos of the 156 on-line.

All I know is this.  A while ago I tried a range of power conditioning products in-home, ranging from around $500 to $3500.  Ten or twelve in all.  Most of them just sat there, didn't notice anything with them in or out of the system.  Amps (monoblocks) were always plugged into them, when those kinds of outlets were available.  A couple of them added their own physical hum to the mix.  The only unit that immediately, audibly, improved the overall sonic presentation was the 156.

The one other product that I would have liked to have tried, but didn't, is the Inakustik 3500.  One member here (wig) had both, and kept the Puritan.

It's pretty simple: find a dealer that will let you try it at home, and give it an audition.  If you don't like it, or it does nothing for you, send it back.

There are plenty of products promoted on this site about which I am deeply skeptical.  But this one, in my own, personal, subjective experience, worked, and worked well. That is all.
