iFi audio SupaQuasar - Active power at its finest!

Welcome the SupaQuasar
Geometrically balanced endgame active power cable.

Endgame
The SupaQuasar is an endgame power cable for your audio setup.

It has no shielding to minimise capacitance, extremely low resistance to maximum current delivery, and is specifically designed for large amplifiers.



Featuring our Active Noise Cancellation 2 technology, it actively eliminates noise across all frequency ranges across live, neutral and earth. Plus the SupaQuasar active power cable is truly geometrically balanced, a first in the world of power cables.

Ground Zero
Using iFi’s unique Ground Zero design technology, the SupaQuasar active power cable creates a central core that is free of any magnetic fields.



The non-twisted central ground wire is surrounded by the live and the neutral conductors as a geometrically-balanced pair double helix which protects the ground wire from any magnetic field. No induction voltage is created in the ground wire and therefore system ground noise is vastly reduced.

Balanced
Each individual power line has concurrent shielding, so both internal and external RFI noises are minimised.

Low inductance, low capacitance and constant impedance are achieved for the entire cable by the use of the double helix power lines. Constant impedance is achieved regardless of whether the cable is bent or angled, thanks to the fully symmetric and balanced geometric design.



The cable is insulated using a polymer matrix, which is comprised of a high-performing thermoplastic that is moisture-resistant and is RoHS compliant.

Continuing the true balanced theme, the cable uses air-dielectric delineation to give the best separation possible between the two balanced pairs of live & neutral.

Leading the way…

• Heavy OFHC continuous cast copper
• Polymer casing for lasting durability for excellent conductivity
• Concurrent shield for each power line for minimization of internal and external RFI noise
• Polymer matrix is unaffected by moisture, amorphous, dimensional accuracy, low dielectric constant
• Air-dielectric delineator, best separation between balanced pairs of live and neutral
• Shotgun ground line non-twisting design significantly reduce ground loop noises

Copper. Gold.
iFi uses the purest copper core to ensure excellent conductivity and our plugs are gold-plated with copper connectors to guarantee the best possible connection.



Finally, the SupaQuasar active power cable is finished in an impact resistant polymer casing for long-lasting durability.

Active Noise Cancellation
Most power-conditioning products engage passive noise reduction through a selection of filters and regulators. While this can be effective, it has inherent disadvantages. Passive noise reduction systems are effective at the top end of the frequency spectrum but often less so at lower frequencies. In addition, passive systems need large capacitors to be truly effective, which make the best such products bulky and expensive.



iFi’s active system uses inverse noise current to cancel out the noise in the mains signal. Noise in the mains supply occurs at different frequencies, depending on the cause. Active Noise Cancellation II technology enables a power-conditioning device that is highly effective at reducing noise consistently across the entire frequency spectrum yet sufficiently compact and lightweight to position within the mains cable itself.

 

It's good that it conducts electricity.

 

I went to zero inductance and capacitance by taking the transformer and smoothing caps out of my power amp, but I wasn't entirely happy with the results. FWIW, it did give me a fantastically black background after about 1/4 second of "burn-in"....

 

Should the last graphic be waveform + inverse waveform = flat?

 

Is it Mac compatible?

 

You make great stuff, iFi, but I think you might have reached the edge of the Overton window with this one.

 

I think there are no more bounds to the Overton window. “Make power cables great again!”

 

iFi's motto is "let's see how much bullshit marketing terms we can throw in". Luckily, it is backed by (usually) good engineering

 

I checked the price, so "you" wouldn't have to, and its a heart stopping 899€.

 

You'd have to double helix my arm to pay that for a power cable.

 

Yes. Fully. But only this kind...



(Expose Yourself To Art)

 

So wait a sec, the active cable is more than a power code, right? It’s effectively a power filter? How much does a decent power filter/power regenerator cost?

 

I know nothing about this ifi product, but my experience with about half a dozen reputable power conditioners leads me to say that you need to spend $400-$700 new for ones that sound good and don't strangle the music.

NOW- Ask me which one I use?

None.

 

Sorry, ifi, but it isn't going well.

As I have said before, and I think you guys agreed, you should target your selling. SBAF may not be as earthy as it once was, but it still has its limits. I'm glad to say.
