Noriyuki Miyajima has had a love of music forever, first as a hobby, then as a specialist dealer and more recently as a manufacturer.  Using real wood, diamonds and delicate coils, Noriyuki prides himself on honesty.  With several patents and a passion that is most clear, Miyajima cartridges have had rave reviews all over the world and deservedly so.  Unlike some cartridge brands Miyajima are made in-house with six dedicated full-time people.  The cartridge bodies are milled using three Roland Camm-3 CNC milling machines; the cartridges are assembled by hand.  Microscopic inspection and full electrical tests are carried out to ensure every cartridge meets or exceeds its published specification.

What Makes Miyajima Mono Cartridges Special?

Miyajima mono cartridges are true mono designs, which means they have only one coil that operates in the lateral plane only.  They have no vertical compliance and cannot therefore be used to play stereo records (to do so will cause damage to a stereo groove).   Asking the stylus to do only one thing, eg wiggle from side to side, means that it is totally insensitive to vertical movement in the groove, and that manifests as very low groove noise, as well as very faithful tracking of the groove modulations.  Most mono cartridges are actually modified stereo designs that have some vertical compliance, and which will pick up vertical groove modulations which are almost certainly noise, dust, damage etc, so in reality a compromise but still probably better than playing a mono LP with a stereo cartridge.  Miyajima mono cartridges don’t have any such compromises and are characterised by very low distortion and very low surface noise, whether we are talking about the Kotetu mono or the (truly astonishing) Zero models.

Why Does a Mono Cartridge Make Any Difference?

Stereo cartridges will make a good fist of playing mono records, but it’s a compromise.  A good mono cartridge does one thing – play mono records – better than a stereo one.  Paul Rigby wrote a very good piece titled “Is It Time For Mono?” explaining this far better than I can, and you can read it HERE.  He summarised the piece by stating “A good quality mono recording makes stereo pressings sound rather gimmicky and toy-like in comparison. I now wonder what I’ve been missing all these years. More than that, at these prices, a steal…a complete steal, the relative improvement in performance is quite astounding.”  Miyajima mono cartridges give you that mono magic, just like their stereo brethren do for stereo records.  Truly magical stuff

Miyajima cartridges are just as likely as any other cartridge to wear out over time, or to suffer accidental damage, so buyers need to be assured that the manufacturer offers an efficient and good value repair and servicing service.  This is most important in the case of Miyajima stereo cartridges because the unique way that the generator system is designed and built means that only Miyajima themselves are able to undertake proper servicing, adjustment and repairs.  While a third part cartridge re-tipper may be able to fit a new tip to a Miyajima stereo cartridge, they cannot adjust the coils and suspension to suit the new tip, so you as the customer will most likely not get a satisfactory result.  We therefore recommend that all Miyajima servicing is done by Miyajima in Japan.

All new Miyajima cartridges supplied in the UK are warranted for 2 years from the date of purchase, against manufacturing defects, and that UK warranty is transferable so not restricted to the original buyer.  Miyajima only honour the warranty in the country that a cartridge was originally supplied in, in our case the UK, so any ‘grey imports’ are not covered by any warranty at all and Miyajima do keep records of serial numbers to enforce this policy.

Miyajima’s 2 year warranty does not cover wear and tear, nor accidental damage, so Miyajima UK have come up with what we believe is a very fair offer for customers requiring cartridge servicing, as follows:

  • Examination, testing and simple adjustment – just a nominal charge to cover actual postage costs  between Miyajima UK and Miyajima in Japan and return.  We will confirm that cost in each instance and if the cartridge return coincides with a regular shipment from Japan, then we won’t charge for that postal leg.
  • Full service/repair – where a cartridge is worn out or damaged (outside the terms of the warranty) and cannot simply be adjusted back to the manufacturer’s specifications, Miyajima UK will offer a new replacement cartridge at 50% of the current UK retail price.  This offer is available only to the original purchaser and not to any subsequent owners.
  • In all cases, we send cartridges back to Miyajima in Japan for examination and testing.

If any of that is not clear, or if you have any questions, please get in touch using the contact details at the top of this page.
