What Shunyata and Furman (SMP) Have in common - Inductance!

Hi everyone,

I've been doing a little online research. The name that seems to come across here on audiogon regarding power conditioners is Shunyata, while @elizabeth and I talk Furman, especially due to cost.


I wanted to point out that what these two brands have in common is inductance. Coils. Coils in series with the outputs.


Furman and others who have licensed series mode surge protectors use great big coils to slow down surges long enough to let the surge protector react. Furman calls it SMP, but the tech has also been licensed to PS Audio and other makers. Essentially this is a low pass filter, which starts working at 3 kHz. That's way down in the audible range.


It's clear from pics of Shunyata's insides that they are using great big coils too. Why? Well, you can make a coil with high inductance, and low resistance at AC.


Anyway, my point is, these two brands share this basic principle. If you want to supplement a Shunyata by taking digital streaming outside of it (routers, wifi, etc) consider this super inexpensive Furman strip:

It's also a great starter conditioner, and the series surge suppression is unbeatable. Furman also has LiFT which I trust works but I've not investigated it very much. Furman makes a boatload of devices, so check for SMP and LiFT for the best noise suppression.

The PS Audio strip which uses series suppression is here:

Of course, saying these conditioners have the same principle is not the same as saying they work equally well or are best for your application. To your own ears be true!


Best,

E

What specs? There is only one listed, "EVS (Extreme Voltage Shutdown) responds to sustained over voltage conditions (137 V or greater)." The rest is filled with features. The telling one, "VIRTUALLY non-sacrificial." You know, meaning not quite.

Communicate with Garth Powell, or Christos Desalernos at Furman, if you don’t believe SMP uses MOVs. It is very sad that you are totally clueless as to what a MOV looks like.

And Brick Wall doesn’t use Series Multi-stage Protection. They use real series mode technology. That’s okay, I understand that you want your affiliate money, and have no qualms in being a charlatan.

I suggest if you don’t like my blog you go write your own.

That's kind of how the Internet works.

Erik- Are you a dealer? In good faith- can you edit your furman/amazon link which clearly shows affiliate marketing? If such links are tolerated, I am sure dealers can post link to their website for sales of their items.

Trying to keep things honest in a discussion.

I am not a dealer. Unfortunately I cannot edit a discussion once it has been replied to, and being sure I don't use an affiliate link is also complicated, but here it is:

I'll keep that in mind for future posts.

Really need to delete this thread, as the PS Audio units I linked to are no longer the same ones. Those seem to be gone.
