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.

Interesting product. I have a question If I may please. If the noise in the mains supply is so low that you can "cancel" it with compact and lightweight solution that can be fit into a cable, why should I worry about it in the first place?

does this cable have the same features as the ifi ground defender built in?

Thanks for asking! Our SupaQuasar doesn't have our Ground Defender built in. Instead it detects whether there's something off with grounding and polarity.

Thanks for your response,

Would installing both products together in series or purchasing one make sense?

The more noise is incoming from your mains to your setup, the more a cable like SupaQuasar will do for you, but fundamentally that noise degrades sound. SupaQuasar provides a compact active way of addressing it no matter the amount, which may (...and in most cases will) make an audible difference. Hope this helps, thanks!

Thank you for the response. This audible difference you mention, is it audible only to humans or can it also be detected and measured with measurement equipment?

Not sure whether animals hear it, but many humans do

That difference is the result of active noise suppression (> 40dB), which is measurable.

Great! Do you have any measurements you can share?

We have our internal measurements, but these aren't for public consumption

You are selling a product that is supposed to decrease noise, you have measurements to demonstrate that it does, but you decided not to share it with the public? That is an interesting marketing decision. Usually when companies have data to prove their claims about the capabilities of the product, they tend to put it on the first page of their marketing material. In an age where it is exceedingly easy to get accurate measurements, may I ask why you decided not to publish these data?

It's easy to get some measurements, but whether they're accurate and/or any telling is a different and rather complex subject.

may I ask why you decided not to publish these data?

Sure. We publish measurements when they're actually needed to address a specific problem, i.e. here:

https://ifi-audio.com/wp-content/uploads/2018/07/iPOWER-Much-Ado-About-Nothing.pdf

In case of SupaQuasar we don't see any problem to address and that's why we'll keep our homework internal. Besides, customers who purchase such products already know what they can do. Hope this helps, thanks!

 

[IAtaman]

It's easy to get some measurements, but whether they're accurate and/or any telling is a different and rather complex subject.

Is it really? As a person who is literate on the topic, I'd say its rather elementary. Cable in less noise. Cable out more noise. But maybe you could help us understand how is it complex to measure whether your product is reducing audible noise by 40db so we make better informed judgements when measurements about it eventually surface.

Speaking of which, if it was a rather complex subject as you claimed, would you rather not get ahead of the potential damage inaccurate measurements can cause to your valuable brand, and publish them in advance? Another odd marketing decision I'd say.

Sure. We publish measurements when they're actually needed to address a specific problem, i.e. here:

I don't know, all of that sounds a bit iffy to me

Besides, customers who purchase such products already know what they can do.

Know is a strong word, but I get what you mean.

 

[iFi audio]

It's fine, I hear you and we can't please everyone

Know is a strong word, but I get what you mean.

We're on the same page then.

Speaking of which, if it was a rather complex subject as you claimed, would you rather not get ahead of the potential damage inaccurate measurements can cause to your valuable brand, and publish them in advance?

No, not at all. We publish specs as the reference point. Some folks into measurements meet that goal and others don't, but at the end of the day it's all good really
