Corelli Corundum Power Conditioner By Akiko Audio

(3 customer reviews)


The Akiko Audio Corelli Power Conditioner is Akiko’s flagship product and it’s a winner! As with all Akiko products the Corelli eliminates distortion and ground noise, without dragging down the dynamics and treble extension…however, this product is substantially more powerful and capable than anything we’ve offered from Akiko thus far.


Product Description

The Akiko Audio Corelli Power Conditioner is the first major high-end product from Akiko and it’s a winner! As with all Akiko products this unit will eliminate distortion and noise, without dragging down the dynamics and treble extension…however, this is by far the most powerful product offered from Akiko thus far.

The Corelli reduces noise without negative side effects such as reduced dynamics or natural quality. A pioneering reference power conditioner that provides your system with clean power, without the use of electrical components and or any active power filtering.

Internally the Corelli contains three chambers made of woven carbon, specifically geared to a unique task. The neutral, phase and grounding signals are separately treated. An extra fourth unit is responsible for the harmonization of the internal high-frequency radiation field. Finally, the device is stabilized with black resin to repress unwanted microphonic effects adequately.

The performance of Akiko products has been shown by measurements. Reducing high-frequency noise leads to music rendering in the audio spectrum that is perceived as a more natural and open experience.

What to expect.

  • A very honest and neutral rendering.
  • Improved timing.
  • Music is experienced as more natural and cleaner.
  • Remarkable improvement of voice rendering and the rendering of acoustic instruments.
  • By lowering the high-frequency noise, listening fatigue is dramatically reduced.
  • Overtones and small details become more audible because of the lower noise floor, making instruments more recognizable.
  • A lower noise floor will submerge deeper into the recording; small details become audible, leading to more emotion while enjoying your music.


Power Cable Option: The Akiko HQ Flex Gold power cable can be added at a moderate increased cost. The HQ Flex Gold is recommended because it is the cable Akiko used to design the Corelli.

Note: This unit is not a power distributor (it does not have outlets).  It simply plugs into one receptacle of your mains outlet, with the rest of the system.


From the new 6Moons Review:

“The Dutch addition can make a very noticeable improvement even in a remote location far away from any big city and commercial industry.”

“Rather than extra body, dynamics and weight, its action is focused on clarity, noise floor, speed and related energy transmission. Consider me sold. The review sample is staying!”


From the Positive Feedback review:

“the Corelli cleans up the power fed to your audio components without using any electrical components or active power filtering in the direct path of the power. The huge advantage of taking this route is that the power is filtered without limiting the current that flows to your components, so the dynamics of the music are not adversely affected in any way.”

“Akiko Audio products are hand made in Holland, and the build quality is impeccable. The Corelli was no exception.”

“The Corelli claim to fame is that it reduces high frequency noise in the power supply, thus allowing your audio components to reproduce music with improved timing, better voice and acoustic instrument rendition, lower noise floor, and less listening fatigue.”

“What became very apparent was the drop in the noise floor, which allowed me to hear subtleties, and nuances, that I had not noticed before. For music tracks, which gradually fade into silence when they end, as the volume diminishes, details tend to disappear. With the Corelli, a lot more of those details were audible right up to the time the music gives way to total silence.”

“What also surprised me is the impact that the Corelli has on the bass. Not only is the bass cleaner and more tuneful now, it is also a lot more impactful. I can now feel the bass on my chest, and in my bones, at much lower volume levels than before. I cannot scientifically explain why a component that reduces high frequency noise in the power supply can influence the bass reproduction like this, but I cannot deny what I can hear and feel so distinctly.”

“I found myself unconsciously bobbing my head and tapping my feet to tracks that before did not compel me to do so sub consciously. The only way to interpret that is to assume that the Corelli has made a positive difference to the way my system delivers pace, rhythm, and timing.”

“it allows my system to deliver music with a lot less effort, and a lot more ease. The music has a more relaxed and effortless feel to it, which in turn reduces the fatigue factor quite a bit.”

“I guess if you add up all the differences that the Corelli makes to my audio system, the end result is that I am able to connect emotionally to the artist a lot better than before.”

“the compression and distortion at musical peaks is significantly less while retention of subtle details during the quieter passages is enhanced.”

“given that the Corelli struts its stuff without impacting the current flow in the power supply to your components, and the fact that it is so reasonably priced, compels me to urge every audiophile to give it a try.”


From the 6Moons review:

“Contrary to previous Akiko products, the Corelli is first to address the positive, return and ground legs of the AC. Its fourth filter then absorbs all the high-frequency radiation inside the Corelli. To control resonances, some parts of it are cast in black resin. It took Akiko over two years to develop this product. A lot of time was spent researching and identifying new more effective piezoelectic materials.”

“Mind you, noise is not always volume dependent. If the noise is in the signal, it’s become an environmental constant. It may not be audible as noise but it still affects what we hear (and even how we feel). As we’ve laid out earlier, ultrasonic pollution reaches us through many channels.”

“The difference was immediate, irrefutable and merciless. Before the introduction of the Dutch black box, the sound already had been open, dynamic and detailed with a very nice soundstage illusion that was deep and wide. The Akiko Corelli maintained this notion but now with a vengeance.”

“What happened to the sound even at very low volume was that we felt inducted into a previously shrouded secret musical dimension. You may think this over the top since a few handfuls of crystals jammed into three carbon-fiber tubes couldn’t possibly do this. Right? We thought so too; until we unplugged the Corelli again. Instantly the sound lost its extra-dimensional communion and returned to being just very good. We could live with this sound for years and be very content and proud of it. However, we now had experienced the substance, the instantly addictive potion that not only worked on our ears but also on our full-body perception. Once the Corelli was plugged back in, there was no short temporary rush but the sustained bliss which only untainted music can bring.”

  1. Nick Wilson

    “I did NOT want to like the Corelli. I didn’t even want to listen to the damn thing. …my brain was screaming ‘snake oil…”

    “where the doors of perception are more than subtly altered. This is the effect of the Corelli, you don’t need to ingest anything to get this effect”

    “At the end of the test session, I’m definitely keeping the Corelli around. I still can’t really explain why or how it works, but it does.”

    “Going back to the LP’s I had listened to earlier, it was a night and day difference. Three areas made a major improvement; pace/timing, upper frequency smoothness and the size of the three dimensional sound field painted by the Virtuosos.”

    I initially purchased the Akiko Triple AC line conditioner and found it made a audible reduction in background noise in my system, so naturally, when the Corelli became available, I had to make a comparison. Although the cost difference was substantial, I found the price to be reasonable given its ability to provide a virtually noise free power grid. As a result, the Corelli allowed the full power, dynamics, and clarity of the music to be experienced in a way that was astounding. The music took on a natural timbre, with precise spacial and harmonic detail, as well as, palpable, life-like dynamics and tempo. It has proven to be, without a doubt, one of the best investments in my system to date!

    I already have interesting tweaks from notable audio specialists (including Akiko) in my system, and all of them have absolutely elevated the musicality and my enjoyment of the original recording in different ways. Then came along the freshly released Akiko Corelli…

    The Corelli that is barely a week old now sits elegantly on 3 Nordost BC Sort Kones, and is connected to a QB8 power strip that powers my Arcam audio system, comprising a SACD Player, Pre-Amp and dual Mono Amps.

    The only expression that accurately describes what the Corelli did to my listening experience is… ”Wow!!”

    The music now propels into an abyss of blackness, where even the most intricate details of the recorded work is revealed with a strong sense of authority. The musical stage has expanded in all directions, and draws you in with an almost uncanny intimacy with the performance. Listening to Anita Baker’s soulful sultry rendition in “You’re My Thrill” (Fourplay: ‘Let’s Touch The Sky’) was simply astounding!

    A truly sound investment!
