Miyabi 47 cartridge: How many hours does it last ?


I have an opportunity to buy a used Miyabi47 cartridge. What is the typical life expectancy of this cart, considering it is well maintained ? How many hours does it really sing without any significant deterioration ?

I remember reading somewhere it only does 1000 hours before starting to lose its magic :(. Is it true ?

I bought a levinson mlc-1 in 1997 re tipped by Van den Hull for cheap.Since that time it has worked perfectly ,last year a new re tipping from Van den Hull again (around 1000 hours since the last time). No problem with suspension...
In an interview read on dagogo, Takeda said that levinson give him the idea for the shape of the cartridge.
I use it on a big plinthed lenco with high end bearing...OL conqueror mk II and am totally amazed by the sound of a 32 years old cartridge.
Nearly all "information" here is about Miyabi Standard Design, but that one has nothing to do or in common with the 47labs cartridge.
Hi Gilles, I heard about this MLC-1 but was confused because of Levinsons involment. So I thought that 'Cello' is the same as MLC-1. To add to the confusion there seems to be also the Klipsch version of 'the same' cart. To comfort or reassure my friend Syntax I need to mention that there are some differences between 'his' and 'my' Miyabi Standard : 0,2 versus 0,25 mV and 2 Ohm versus 4 Ohm in the 'his'- 'my' order. The 47 labs I would never buy because of the (plastic)looks, not to mention the performance.

Takeda

Maybe one could think of the "duck" that quacks in a different way. It is similar in that it is a persona that is representative, but not true to the underlying flow of energy. As it has been said elsewhere, this master designer Takeda did something very unique and special for his favorite child, Standard.

The rest of these ducks, nice ones; however, that is marketing.

Mostly Fun,

Dear Stich, I wish that I invented this different 'quacks'.
But the basic proposition was that they 'quack' in the same way as they look. I thought about to promote Syntax specimen to a better looking duck but was confronted with the same 'logical' problem because they are 'per definition' looking the same. So I give up verbal diferentiation and used numerical kind. But, alas, those are never funny. BTW who cares about difference between 0,2 and 0,25 mV or 2 Ohm versus 4 Ohm? However the price difference may still hurt.
