Koetsu cartridges. They must be something special.


It seems that quite a number of Audiogoners have Koetsu, or a few of them. Different tables, different arms, different speakers but Koetsu cartridge.

Why ?

I have never even heard Koetsu.

Thanks a lot mulveling!   Great details!

I heard once Tannoy sound, not that high-end you have, i admit most impressive sound and full body, but never sound like boxed speakers.   My speakers are Maggi's MG-20, i found them middle in full body, but incredible spreading sound.

Interconnect can make significant differences.   I used to have Transparent, its incredible at full body, with my Krell they sound muffle, probably due to un-matching gears.   Now I'm using AQ, razer sharp but thin in comparison. 

Well, based on these descriptions i felt tempt try one Koetsu.

Yes, I saw that video. 

Jonathan Carr was featured in a video where he explained the actual assembly process of Lyra cartridges. The main artisan for Lyra is Mishima-San. However, there are a number of apprentices who do preparation work. And the final adjustment and tuning is always done by Mishima-San, so there is still a division of labor within the Lyra shop. Carr claims that the total annual output is 1200 cartridges. See the following video at around 17:15 min

I suspect that inner workings and actual assembly processes of Koetsu cartridges was closer to the Lyra model where the Suganos’ were more involved in the final phases of the assembly and there are apprentices on site to assist. And these apprentices are now called upon to carry on the Koetsu Mantle. That must be the case, and the lore of Sugano- San as the sole maker is myth.

Looks good to me! If they use the same formula, same parts from the same suppliers (which Koetsu spec'd and cultivated over the decades), and have skilled coil winders / cartridge assemblers - I see no reason why they wouldn't sound the same as before. Some tweaks & changes here and there might also make for an interesting new take on the classic Koetsu sound, and could be appropriate for this Koetsu v2 (v3?) launch. 

Then there was Koetsu's stash of platinum magnets that supposedly can't be had anymore (at least not without a LOT of investment). I wonder if that is still in play / available for future platinum models.
