Anyone tried a Furman conditioner

Hi all,

Has anyone tried a Furman power conditioner?

They make some for very reasonable prices.

looks good, where do you get them from ?

Here looks like the place:

It would be interesting to see how they compare the the very popular Belkin units.

I know some will scoff at this question, but is there a large difference from something as cheap as this to say a top end Iso-tek unit, anyone have any experience?

Hi Martin, a friend of mine has an Isotek & I have a few Belkin PF40s & a PF30. Ok, so it's not one of these but in reality there won't be a huge difference as long as they are properly designed ;)

All these filters are are effectively made up of differential mode & common mode filters, which are simply windings of wire on some form of core to create an inductor. These are followed by capacitors to increase the rolloff characteristics of the filter itself.

While they could all be implemented in a different way, the end result should be similar, again assuming they are well designed.

The problem is is you need to determine the maximum impedance that you are willing to put between the mains line & the equipment. Ideally it'd be zero, but that is physically impossible :eyebrows: So the chokes have certain impedance which increases at higher frequency & decreases at lower frequency. Most interference is pretty high in frequency so a high impedance will prevent this getting to your kit.

The more powerful your kit is the lower the impedance the supply needs to be to prevent the mains voltage from dropping due to the load. So in reality you need to use pretty thick wire on the inductor to keep the impedance low, you also need to design the thing so it doesn't filter at too low a frequency or current pulses charging the power supply capacitors of your amplifier will be affected - thus altering the sound.


As an example the PF40 when new was more than a few hundred pounds & works as well as my friends Isotek (can't remember the model right now). But the Isotek is made of nice thick slabs of laser cut aluminium. The money on them has really gone to the fancy casework, where as the PF40 isn't as fancy but does the job just as well.

Can't comment on these things as I have never used one. But if they are well designed I'd expect them to do what it says on the tin :D

So the consensus is that it should work just fine? Im tempted - Furman M-10x E is now available for 88 pounds delivered so I guess its worth a shot?

Can someone explain to me what "protect all your equipment up to a 10-amp load" means? How much I can actually plug in?

cheers :)

EDIT: I think this is more or less same stuff but cheaper?

What are you going to be using I would tend to avoid power amps and bug integrated amps as will do the opposite off what you want but other equipment should work fine

I was looking for an upgrade to Tacima CS929 Im using at the moment.

I would rather an APC my H110 has cleans up power nicely and is high current.

Just plug in your gear and listen, what more is there to do? As for a PF40 or PF30 working as well as an IsoTek, be serious young man! :) On the end of what sort of system?

thx

I dont think that those are available in UK?

I was thinking about it - heres one of the IsoTeks - GII Solus:

upgraded to "minisub"

Furmans Elite something

My impression is that once those products are marketed as "hifi" one can witness fascinating process of upgraded looks mixed with increased amount of audiophile air inside:)

Here's Belkin PF40

Im being slightly cheeky here of course. However I quite like the no nonsense attitude of products designed for "pro" market. After all, if something works inside recording studio - surely its quality will be sufficient for home use as well?
