To any body that may be considering this cables, just got these I was not expecting to hear a difference with my little Iotavx (I bought them for the denon pma sx11 really), I heard a difference immediately I did not want to say nothing (I thought I was just imagining things) but Then my wife walked in the room and said why does it sound different, she had no knowledge of the cables....I did not think that she would notice a difference, but talk about a blind test....and these are the cheap regular ones. My dac is the chord Qutest, spikers Ls50 meta and I do have and upgrade power cord for the Qutest and a clean power supply for all the audio gear man it all adds up really nicely....can wait for my amp to arrive. These cables are cheap but I'm rather impressed thanks for the great review to Tharbamar. Forgot to mention I also have 2 REL Ht subs connected to it That's where I noticed the biggest difference the base.

I am so amazed by the SMSL D300 and the sound (magic feeling) it is pouring into my brain based on your recommendation, that I immediately went to purchase these cables that are almost the same price of the DAC, because the DAC is THAT good and deserves everything I can help it with. Once again, THANK YOU for your recommendation of the SMSL D300 dac.

These power cables are great and, imo, beat out much more expensive cables from Nordost, Isotek & others. There’s something inherently correct about their sound, no emphasized frequencies or focus one one thing. They just flesh out what is already there, make it bolder and more alive. Curiously, the Supanova is technically the better cable yet I prefer the Nova for my solid state Hegel amp. The purifier on the Supanova expands the soundstage and gives incredible tone purity but at the slight expense of dynamics. I prefer using it on my DAC and phono stage. Highly recommend these ifi cables!

I have the ifi Nova and it makes a difference...no interference in or out of cable as to not effect what it's plugged into or other cables

All I changed was to a Pangea 9SE mk2 on my Denon pma a100 plugged direct into wall and Technics TT and Denon dcd a100 into $32 SS6B Furman filtered power strip. No more slight TT hum which was a pain and much darker background. Really everything easily sounds better, even less record surface noise with just those two changes. Hard to believe, I wouldn’t unless I experienced it. I would like to add an IFi power chord to the CD player, just using stock chord now. TT sceptical what that would improve but might anyway.

A while back I bought a Furman Elite 15-DMI power conditioner. I didn't notice much difference, but at least I had better protection. Then I broke down and bought some $30 power cables off Amazon that DMS recommended. I immediately noticed that my solid state gear was closing the gap with my tube amp. The sound stage was more natural and believable. Also, I brought out my oldest amp/DAC and found that it's resolution was now on par with my newer, more expensive stuff. I never thought power cables could make a difference, but I guess they do. I can understand better if you have a conditioner, making sure the power stays clean to the component. I am skeptical about plugging fancy, passive cables right into the wall though. Does ifi suggest the use of their in-line filter cable if you already have surge protection or a power conditioner? Normally, you do not want to stack protection circuits as they can actually cancel each other out by not properly arresting big surges.

Nice demo, I definitely heard the difference. Nova is thicker sound compared to generic cable, while Supanova sounds the clearest among the three, am I right? A question, I have a fairly good dac amp combo Questyle CMA15, do you think Supanova is much better than Nova in all-in-one?

I purchased an audioquest nrg y3 and didn't notice any change after two weeks then I purchased a pangea ac 14se and that one made a difference with my yamaha a s801 it did improve clarity & bass just a bit but noticeable so its a keeper and the build is incredible. So i tried the pangea on my new Sprout 100 and on that I'm not seeing any change. So if diving into power cords buy a few.

Supernova for me!

Thank you for reporting your observations. Please advise how these compare to your Oyaide and other diy PCs. Like me, if you can't hear the difference or don't think the price is worth it, don't buy, just like other equip.

It's a good review and soundtest man! $350 is pretty affordable even for a hobbist is like me considering that there's a noise filter installed. iFi is also selling usb noise filter isilencer+ and switching power supply ipower+ with noise cancellation. I wish there's a chance in the future that you could also do some test on them.

Please try some Wireworld cables…

I would like to ask : DAC, Pre-amp, Amplifier : would component is it the most important to have a good power cord?

Solid gold cable risers make your system sound even better.

I didn't look I think the first one sounded the best

Do you use an external clock in your system? Do you think it would improve upon a Gustard R26 DAC?

Nice sounding cables. The generic cable sounded awful and the two iFi cables sounded much better. Impressive.

Yesterday my Supernova arrives. My Test Equipment: Kef Meta Lexicon RV9 Nvidia Shield modified Power suppy At the begin i change Nvidia Power suppy to Supernova. My wifes First comment: Sound more clear, Pictures have more colour TV. She isnot s Fan of Hifi!! My comment:" This clearness in Bass areas... Many more Details at TrueHD films. More room. Digital interferences are gone... I compare with tertellus 200eu and phonosophie 500eu cables. Audioquest Hurricane > 1000eu. All Power cables are better than normal Product cables. Supernova kills them all with a big advantage. I will change any device to Supernova. I was really confused because one wire on the power supply made that difference. Changing from Denon 6400h to Lexicon RV9 was just as big.. Best Deal for 500eu!!!!!

Do you also use these wires in your walls, otherwise how is adding a thick cable after a thin one going to make any difference...

if you have good power condition buy the Nova cable use the extra money buy a ground box to your source will have better result

Thank you very much for the comparison video. I've been listening to the ifi nova model, but I don't have a chance to listen to the supanova. is the improvement clear? I'm also currently testing a silver essentialaudiotools, have you heard? Thank you

Would you recommend using the Supanova on an amplifier? I have read, and heard for myself, reduced performance from the amplifier when plugged into a conditioner.

I was hoping to hear more of a difference between the three sound test at the end. Even though I know it's through KZfaq and not live, I've heard sound samples where power cable swaps made a huge difference but those cables were out of reach for me. These seems to be more accessible and I would buy them immediately if I can hear the difference. I tried to through the Aeon Open X headphones with Topping D70s and Burson Funk but can't seem to make it out. Maybe the last one have 1% more air.

Could it be good for powered tower speakers and subs ?

Will you ever do DAC shootout that would be more interesting to hear the differences between them :)

The graphs look pretty similar to me.

is it also useable for video? for lets say a 4k projector?

Ηi pals .I have not heard these two IFI power cables but IMHO they are not inexpensive and have tough competition .I am using KIMBER PK 10 cables for both amplifier and cd player and i am quite satisfied with them .I 've heard the Pangea ac 9 mkii at 190 euros/1,5 m and liked it.There is also a cheaper alternative that does the job sufficiently = the DIY shielded LAPP olflex 110 cy 3x2,5 mm2 at 6 euros/m for those on a tight budget . P.S . good power cables do really make the difference !!

Hi sir, is it still safe to use even if my supanova reads both red light(missing ground)?

Is there big difference between Nova and Super Nova?

Got a Pegasus DAC, which one do you recommend?

You can achieve same audio difference switching between much cheaper audio cables.The gauge and the length makes the difference here.OCC copper is preferable for power cables .Thats it!

Do you realise that the graph don''t show any noticable differences ?

Gene from audioholics is rolling his eyes right now

Just like others say, I don’t buy that. Audible difference seems just physically impossible here. In my country we call it Audio Voodoo.

Your acoustic panels are placed to high, what are you thinking?

My Amazon Basics Oxygen Free Pure Copper (no aluminium) speaker wire is out for delivery as I'm typing this . . . eat your hearts out Kember clones, hehe

For that price I would get a new pair of iems or something else that actually does something

Does the first "like" win a new power cable? lol

Snake-Oil: Proper sized power cables that are well constructed are all you need. Once you do this, everything else becomes snake-oil. Are you telling your viewers that you can hear the differences in the graphs?

dude, those stalagtites on your graphs ARE THE SAME!!! jeez', smh' . . .

just for the sake of beauty, nothing more.

cmon tharbamar you're better then snakeoil

Sorry but time to unsub, snake oil. Check Audio science review if you need proof.

Snake oil.

By the time you buy all this gear You will be broke...where do stop..

So after all conversions and in lossy youtube format you want to provide difference between cables? Hahaha. So cute. Audifilic tradition do nothing, hear nothing but speak.

boring, boring,

Just imagine how the 1.5mm2 copper lines in your walls are organised... Optimising the last 2m of the whole power line can not make any difference. It just cant; at least not on our planet...

Suggestion, take your noise and performance measurements on your amplifier output before and after using any / all of these power cables. You will measure ZERO difference as your amplifiers power supply is designed to regulate the power and eliminate AC noise. Isn't the primary reason for using these cables to reduce AC noise? Do you really think that a 3 ft power cable (or worthless power conditioner) from your amp to the wall is going to change the sonic quality of your amplifier and alter power characteristics of AC power sent many miles over transmission lines and the 14 gauge wires in your house? If the difference in noise is unmeasurable, can you magically hear a decrease in noise, or the sonic quality of your amplifier??? Plenty of proof this is BS on Audioholics and Audio Science Review. Psychoacoustics can be a powerful placebo. They look great and a person can buy whatever they want, but these cables are worthless. If you "think" they improve the sound great, whatever flips your trigger as they say. How about doing a blind listening test with 5 audiophiles between all cables and see if anyone can actually hear the differences? Pick the "best" of the bunch on a regular basis, or pick specific cables. That would be great video. Now on to speaker cable floor risers...

Lol Snake oil. All physics. And all is known surrounding sending current through em.
