Cartridge inductance


I am considering using a Hagerman Piccolo Zero as a headlamp for the mm input of the Trumpet mc.  Cartridge will be the new Mutech Hayate.  Hayate output is.45 mV and impedance is 1.75 ohm.  Inductance not listed.  I am concerned that this could result in clipping and could damage my amp or speakers.

Does anyone know how to find inductance for this or any other Japanese cartridge?  Piccolo impedance is listed as .06 ohm.

Thanks, I realize that.  The issue is not having specific information “To determine if your cartridge is suitable for transimpedance operation, it's inductance (in uH) divided by it's resistance (in Ohms) should be less than five. This ratio determines resulting bandwidth. ”

 

No, Jason. A typical LOMC has inductance at MICRO-Henry levels, typically less than 50uH, which is about 10,000-fold lower than any MM (typically about 500mH).

Oceanica, I am not sure what they are getting at but let's say the typical LOMC has an inductance of 10uH and an internal R of 2 ohms. That would qualify because the ratio is 5, but I guess they are trying to get across the idea that for a low output MI cartridge, where the inductance is quite a bit higher, mating it with the Zero is not advised.  I don't know why they wouldn't just say that outright. It is easy to imagine that some specific LOMCs also would not qualify, if one took the rule completely rigidly. Like the ratio might be 6 or 7 in some individual case, and I would not see a problem. Maybe ask Hagerman.

The Mutech Hayate is a very new Cartridge Launch.

The use of Gold to dampen is off interest, AT was doing this Coating on Boron Cantilevers many years past. 

It is also interesting how the Company has flagged up Sound Quality differences being produced from Rhodium in use, not that I have been demo'd to support what I have been informed, but cable producers I know, who put a lot of attention into Connectors have rejected Rhodium as a costing substance many many years ago.

I have avoided Rhodium as I trusted their findings from experiences had.

It also looks like they have gone to an leading industry specialist to supply other metals that will impact on the signal path.

Again AT were using Pure Copper OCC Lead Out Pins in certain cartridge models and now the Hayate has Pure Copper OFC as the Lead Out Pins.

A Friend who has been investigation a selection of Cartridges has informed me, expensive Cart's looked at have a Brass Pin with Gold Plating.

It is nice to see R&D that has been seen as methodology to eke optimisation at other eras in Cartridge Design have found a purpose in the most recent era, what's missing is the Boron with Gold Plating used on the Hayate.

From another forum, I am a follower of a forum member who has used most Japanese Cart' Brands and has models compared from the ranges from Brands.

The Hayabusa was made known to compare very favourably to Brands models costing 3 x the cost of the Hayabusa. I will keep a look out to see if the Hayate is added to comparisons.

I think you might be referring to shakti?  I have read his comparisons and have found them very helpful.

 I am mainly concerned about overloading the phono stage due to the additive gain that might occur.  I think @lewm might have the most practical solution, just start at very low volume and listen for distortion.  
worst case, I end up using the trumpet mc without the piccolo zero for that cartridge.

 

The Hayate is even more on my radar now as I have known the Hayabusa as a £3Kish cart' for numerous years and had the this with MSL as a Brand of Interest.

The Hayate is not found at £3250 ($4400), as an import model, this knowledge keeps the Mutech Brand as a interest.
