Our quest was not for better spec, but “Dense sound.”

n this digital century, music experience has been all digitized. We buy CDs, download and stream music even in Hi-Res format from the Internet, You can access to your favorite music with one finger operation wherever you are.
In such a world, you dare to listen to vinyl records?

Records are troublesome. They require careful handling and large space for storage.

You must be weird… No, you are not. You want to experience something significant that you cannot from digital sound.

We know exactly what is the “something.”  Because I myself had the same feeling.

What you want must be

Thick, dense and pleasant sound that you can only enjoy from analog sound.

Something that cannot be brought from a digital source.

In fact, I had the desire for such sound experience when I started to take the road of vinyl and tried out whatever cartridge in the market came in my way. But nothing was truly satisfactory.

If you want simply “thick” sound, MM cartridges will do the job.

But a cartridge that can carry as much information as an MC type, and at the same time, “thick and dense” sound quality was really hard to find.

No wonder.

Most cartridges out there recently have very stereotypical specs, low impedance, line contact stylus, boron cantilever… all aiming to produce “digital-like” sound.

Yes, they are capable of flat frequency response, hi-res sound, but are in the first place, not made for “thick and dense, pleasant” sound peculiar to analog music.

Such cartridges do a good job when you play a newly pressed flat and flawless disc.

But when you try any old original disc, the cartridge would faithfully reproduce all the irritating rustling noises on the groove. The sound is far from dense and heavy, as you are too disturbed.

I went through the same experience.

Then I reached the idea of making up my own cartridge that realizes the dense and thick and pleasant sound of my desire. Long collaboration with the excellent craftsmen in Japan created this “KOI-OTOcartridge.”

 

Time to stop listening to the records with theories and specs. “KOI-OTO” is the only cartridge that delivers unprecedented sound experience without any difficulty.

Keys to “dense, thick and pleasant sound” are

ultra strong magnetic power × carefully selected solid wooden body

Ultra-strong magnetic power is generated from Neodymium plurally allocated inside, based on careful calculations of optimal magnetic flux

We used Neodymium magnet, one of the strongest in the market, so that the tiniest move of the cantilever through the stylus can be clearly sensed and promptly transformed into the sound.

The powerful magnetic force yields outstanding dense and solid sound, marking 0.45mv, strikingly high output as an MC cartridge. 

 

Carefully selected solid wooden body signalizes “KOI-OTO’s” unique design.

After examining all kinds of materials to make desirable dense sound, we have reached the answer to use wood for the housing (body).

We tired several dozens of different species of wood. It is generally said that hard materials like ebony are suitable for audio devices. But after the numerous test auditions we found that such materials would just make the sound ordinary.

Flexible material is more suitable for the case to reproduce deep elegance of the sound that comes from the stylus.

Our craftsmen carefully hand-picked solid material, and created the special shape by delicate handwork.  

 

Make this cartridge your daily basic

Just play KOI-OTO once and you never want to return to other cartridges. More and more users have this experience.

You would also start pulling out the discs in your library and try them all with this cartridge.

Indulge yourself in the pure sound of the records.

Technology and affection of cartridge artisan left in Japan

Major manufacturers withdrew from the analog audio business when the vinyl market dwindled, with just a handful of craftsmen in Japan remaining in the field. They have managed the superb traditional analog technology and preserved the record culture. The cartridge technology in particular has been the country’s stronghold.

It is well known that many of the high-end cartridges out there now are by the hands of such Japanese artisan. We got their cooperation to create this KOI-OTO , and they enjoyed the new challenge to realize “dense, thick and pleasant sound.”

KOI-OTO Advanced

 

It is dark, and clear everywhere.
KOI-OTO Adopted an advanced grade needle tip like the KOI-OTO Silver, using a stable copper wire coil, it is an advance model that raised the resolution of the sound more.
In addition to the sound pressure of the middle and low tone, the high resolution which separates each instrument firmly reproduces the pleasantness of music.

Although it corresponds to every music genre, it is inevitable to “annoy” without thinking about its resolution and power when you apply a record such as pops, AOR, fusion etc. since the 70’s.
If you are confused as to which way to do in the KOI-OTO series … Please select this advanced model.
