Furutech Flux-50 Filter

This thread reminded me that I have one! I used to use it with a Shunyata PC that I own. When used, you can definitely hear the noise floor drop with the FF50 in the chain. A layer of grunge just gets eliminated. A worthwhile investment if using stock PCs, and works really well even with Shunyata's as well!

Jeff AV Solutions sells them I believe, and I think Sunil (recently joined) sells Furutech as well.

HTH.
 
I have a filter between each amp and power cords. Definitely worth the money spent, especially in lieu of plugging the amps into a power conditioner. Got mine from Jeff at AV Solutions.
 
I use them on every component in the network. Swear by them. Couldn't go back without them. :thumbsup:

Do you use the Flux-50 Filters in place of a power conditioner or in conjunction with one?

Pardon me here to butt in:)-- I use one into my PurePower 2000--Tried it on the Poweramp/Phono Stage/CD Player/etc--I found it gave the results with the PP

The only PITA with that way --is the standard F-50 IEC's input and out--you need to use those wobbly Shunyata adaptors that fit poorly and over priced in order to accommodate the 20 IEC's

Highly recommend the Fluxes--- the noise floor is rendered much much lower with them installed

I say money back trial would be the way--if you don't find any improvement--?-fire 'em back!:P

Thanks Bruce! The reason I asked was because my Audience power conditioner made a tremendous improvement with my CD player and preamp but limited current and dynamics somewhat when I plugged my amps into it. I'm thinking a reasonable solution would be to bypass the power conditioner with my amps but add a Flux-50 for each of them. Others have told me the Flux-50 is not current limiting. Has anyone found the Flux-50 to limit current and dynamics to their amps?

Also, do you have to use Furutech power cords with the Flex-50's to maximize their performance? I really really like the sound of my AU-24SE power cords and would hate to change them.

Thanks,
Ken
 
Answers to questions based on my experiences.


  • Flux-50 hang off every component including amplifiers. They are not current limiting.

  • Each power connect utilizing a Flux-50 in my system connects to passive power distribution, either Shunyata Hydra Talos or Shunyata Hydra Cyclops.

  • I use conventional power connects that do not having inbuilt networking or passive electronics which may conflict or compromise performance of either product. The cables I use include Siltech Ruby Mountain II, Furutech PowerFlux and custom lengths of Furutech 3TS20/TechFlex Flexo Conductive/Flux FI-50/52 combinations.
  • I have tried Flux-50 on Shunyata Acanocoda Zitron into the Shunyata Hydra Cyclops. The result was unfavourable in my system. I do not use any Shunyata cables as I have not had positive experiences with their Zitron cables for various reasons.
  • For those considering using the Flux-50 on Shunyata power connects, you may wish to consider their new shielded Sigma cables claiming to do something similar with the updated passive electronics built into the plug.
  • I have heard others having success using the Flux-50 on an active power conditioner/regenerator's input. I would think that adding additional Flux-50s to the components would yield further benefits.
  • I have found that Flux-50 benefits are cumulative as is typical within a power conditioned/distributed network topology.
  • Furutech will factory terminate with an FI-52 option, negating the need to use clunky IEC adaptors that may compromise performance. It is a special order so I am told.
  • Would I buy more as the need arises? Definitely, yes.
  • Should you use more than one in your system? I think so.

YMMV

Alpinist, Great question.

Steve, Allen, Anthony and Bruce, Great responses and thanks very much for your help. That said, what I am really trying to assess (as is Alpinist I think) is how the Flux 50's perform with no other conditioner involved (be it passive or otherwise). Have you ever tried your Flux 50's without your Shunyata or Pure Power gear in the equation? The Talos and Cyclops are much more than just distributors as they both possess the technology of the Triton (but no surge protection in the Cyclops). Of course the Pure Power is an excellent regenerator.

I am contemplating using the Flux 50s exclusively with Furutech Powerflux PC's and GTX receptacles and foregoing a distributing conditioner of any kind. I have blocked noise coming into my system from the outside with my Torus and just want to isolate my components from each other and minimize any negative effects of a conditioner (i.e., minimize loss of instantaneous current and dynamics, high frequency roll off etc.).

If you have tried these scenarios can you contrast the performance of your system with the Flux 50's alone to the conditioner alone and then to the combination of both? Your thoughts on this approach would be greatly appreciated.

Thanks,
 
Paul, I've only used FF-50 without a PLC, direct to dedicated 20amp lines (with Furutech GTX receptacles as you have). So Furutech GTX -> Shunyata Zitron PC -> FF-50 -> Component (amp, pre, CD player). The biggest difference was with the amp, then the pre, and less so with the CD player (K-03 back then).

HTH.

That is pretty heavy damage! If you need to do that in front of every piece of gear or amplifier as asindc suggests:

I have received some amazing results by trying to tackle the problem before it exists. You might want to take a look at this thread as it might save you some money.

As a conclusion I do believe in noise filtering, isolation, and the Furutech is without doubt doing a good job. But at the same time it is better to prevent a disease than to cure it.

Glareskin, IMO you have addressed part but not all of the problem. I see three goals in a properly designed electrical foundation:

1) Block the system from the outside without limiting instantaneous current or current draw. (You did this one.)
2) Star ground the system to avoid ground loops caused by electrical potential deltas at each component's ground without limiting either instantaneous current or current draw to each component. (I presume you took appropriate measures but your post did not have specifics in this regard.)
3) Isolate each component from the significant other components in the system without limiting instantaneous current or current draw. (it does not appear your system addresses this concern.)

Depending on your incoming power, the third point can often be the most damaging. SMPS's, large amplifiers, digital gear all wreak havoc on fellow components.

Thanks Paul for your reaction.
1) correct, that is done
2) I am not sure if it qualifies for star grounding. I have an extra and dedicated (thick) ground line to the central grounding point where all the ground wires connect. The two power amps share a line and the pre-amp and streamer share a line.
3) Doesn't having a dedicated group (fuse) in the switch box do that? If not I do have room for improvement...
 
Well executed star grounding ensures each component will see the same electrical potential at each ground. This is important because tray voltages in any particular component will leave the overall system through the most attractive grounding route in the system. The problem with audio is we provide intra-system (inter-component) grounding paths through our component interconnects. If a ground at one particular outlet has a higher positive charge (is more attractive) than the others this will cause the voltage to run through the ground on your interconnects from one component to another and exit through the more attractive route. This is called a ground loop which can cause a hum in your system.

Star grounding is the best way to avoid this which involves: 1) a single isolated ground for your entire system; 2) making sure each run to the receptacles is identical (i.e., same type wire, gauge, and most critically the same length); 3) avoiding runs coming close to any magnetic fields or circuits along the way that can cause inductance or parasitic capacitance in the neutral of that line that would vary from the other runs.

The bottom line is if you have no hum, you have no problem; that is why, based on your description, I presumed you are close enough in your execution that your stray voltages are exiting through their respective grounds as opposed to across interconnects causing a ground loop. The good news is you did this while still using multiple outlets which will not limit your current draw. Many accomplish star grounding by using just a single outlet for the entire system. A major compromise IMO. That you didn't is a huge step; great job.

That all said, you might find a bit of improvement by isolating components from each other's noise. If you look at doing this just be extremely carful not to limit instantaneous current (ergo my interest in the Flux50 for this function only as opposed to a more intrusive conditioner).
 
Thanks for the great explanation. Well basically I don't have a hum so probably I am fine. Did you measure the value of your ground cable? Did you install an extra ground pin?

And for the isolation filter did you make a comparison to the alternatives from HMS Energia and Audioplan? Also what about the other Furutech products like Flow-28 and Flow-15?

Anyhow it is amazing what the result of power improvement is. I will definitely extend here.

No I am building out my system now and don't plan to measure just follow rules stated. Did you install an extra ground pin? It is critical, yes I plan to.

And for the isolation filter did you make a comparison to the alternatives from HMS Energia and Audioplan? No but I will look at them. Thanks for the lead. Also what about the other Furutech products like Flow-28 and Flow-15? I would think they are also excellent, just with a little less capability.
