The Mutech RM Kanda Hyabusa

What they say suggests that the input impedance of the Channel D L20 (odd name for a very expensive phono stage) must be less than 25 ohms, but to work well iin current mode with cartridges like the Mustek or the Haniwa would require a phono input impedance of less than 1 ohm.  The field of choice is quite narrow at that specification, but like I said, these cartridges can drive in voltage mode, providing there is enough gain available.  Same old problem.  Didn't mean to side track your discussion.  One of these days I will have to buy a current drive phono stage to satisfy my own fascination with the idea.

It's full name is the Seta L20. But this is the one getting the very positive reviews http://www.channld.com/seta/linoC2.html  
If you go to the specification section in the manual they list the input impedance as less than one ohm. I was also mistaken. It will only work with cartridges <10 ohms not 25. The lower the cartridge impedance the higher the gain. Up to 85 dB if you use the highest gain setting. Inputs are only balanced so people might have to rewire their tonearms, no problem for you. There is also an RIAA bypass so you can use it with Channel D's software RIAA correction. I already have Pure Vinyl and I am dying to give it a try. 

"<10 ohms", makes more sense to me, especially if input Z is <1 ohm.  You'd be surprised to find that most of the phono stages that claim current drive operation actually have much higher input Z, which means they cannot really operate fully on current drive with some of the cartridges that have very low internal resistance.

It certainly seems to be the way to go with very low impedance low output cartridges. I'm psyched to try it.  

A Lino C 2.0 + ZYX Ultimate 100 ( impedance 4 ohm ) is my current setup. The adjustable gain is set at +12db which achieves approximately 75 db with the 4 ohm input. Rob at Channel D had cautioned that using the highest gain may cause distortion due to overload margin. However, as I am also using a Lightspeed Passive Attenuator, I need all the help I can get in the gain department. My sense is that with my setup, an impedance of 4 ohm is really the upper limit of MC cartridge choices. 

I have therefore been extremely interested in low impedance MC's, My Sonic Labs, Transfiguration, Lyra.... and of course Mutech. I think Mutech makes part for Transfiguration and it uses parts from My Sonic Labs. While I am not in a position to upgrade or acquire a new cartridge right now,  I am especially interested in Mutech. It seems that the RM-Kanda Hyabusa is an export model, while the RM-Kanda is the top of the line retailing at $6,000. But with impedance or 2 ohm, it should work very with the Lino C.
