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 ?

Is this Miyabi 47 really a cartridge made from Takeda??? Some say, it is not.
Takeda himself does no more repairs, when you find out who made it, Service
shouldn't be a problem. Btw. the Miyabi Standard works very will with all kind of
Arms and is really outstanding from sonics. Takeda used that body for a few
manufacturers, Cello, Krell, Mark Levinson, Red Rose ... but he said, the
Standard was his own voicing, he sold it for his own and it was sonically his
best design...
Dear Syntax,'it looks like a duck, swims like a duck and quacks (sounds) like a duck, it probable is a duck'. But I understand when 'someone' pay the full price for his
Miyabi Standard this 'someone' does not like to hear that someone else got the same 'duck' for 1/4 of the price. I am grateful for your advice to look for this 'duck' but
we from the Balkans enjoy in particular such kind of coincidence. Some of us need to 'enjoy' such a 'pleasure' for the rest of our life. I bought this Krell KC 100 a la Raul: 'one never knows'. Beside with the (metal) box I was staggered by the looks: 'looks like a duck'...etc.
I was even more flabbergasted by the sound by my first test in my second system which function as my labaratory. After 20 min. this cart was the first to make the promotion to my main system. 'It' (the duck) got the company of my Reed 2A and substituted the previous occupant the Phase Tech P-3G. If I only can find the Cello which looks to me like a real beauty.

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.

Regards,
