The 'tube-transistor' enigma by MC carts?

By accident I got to know an guy from Swizerland who has
worked for years as technician (R&D,testing,manuf.etc) by
Benz. I made some joke about 'Zelle',the expresion he used
to refer to carts,by asking if the carts are made by
prisoners? ('zelle' is 'the box' in the prison) He appreciated my joke and explaned to me in 2 sentences
something I never thought about. There are 2 kinds of
'bobins': iron and the other kind. The 'classical example'
of 'iron' is the Ortofon SPU. The advantage: stronger signal and some kind of 'pleasing warm sound.the disadvantage:(more)distortion.
The 'ruby-cross' bobin has (much?) less distortion but can
sound 'thin' depending on the rest of 'the chain'.
This is obviously the so-called 'Holistic' approach ;
aka Rauls 'it depends...'. Me? Because I can't cope with
more then 2 variables at the same time I am for 'simplicity' approch. The best 'definition' of this
approch is from O.Wilde:'I have the simplest tastes. I am
alwys satisfid with the best'. So I am still seaching.
Raul will you please bring (more) light to this issue?

@bimasta  it's nice to run into somebody with an FRMC201.  I have had one for a while when I picked it up on a curiosity. I absolutely love it, it is fantastic Mounted on an ET2.   It is an air core  design with I believe .17 mV output.

Addition, I don't know why exactly Lukatschek dislike ''iron''

(core) but he stated '' I don't like iron anywhere in the signal path''

(see above). I now remember his comment on Fremer's

review of his LP s. He blamed Fremer for using SUT by

his listening tests. One can see this as one more argument

against SUT's ( see Raul) but he used more wire for the

coils to get output at an ''reasonable level'' of 3.6 mV.

That is to say that one can avoid SUT's with this kind of

output.  I have no idea if SUT's can be made without iron

core . I am very fond with my Denon AU-S1 and don't

believe that this SUT uses any iron. But I also know that

''believing'' is not an strong argument.

Last month i have opened my headamp designed by Nakatsuka-San. The reason to unscrew it was expired batteries. It was a first time when i saw input resistors like that. Those resistors looks like an MC cartridge coil and made by winding the wire to a coil that has no inductance in a special process. Those resistors made by ZYX to transfer the output signals with no noise and no inductance at all. They are made of pure coil wire of MC cartridges, cryogenically purified. Signal from LOMC cartridge should go into ZYX CPP-1 Headamp’s resistor wihtout any influences from resistor noise and inductance. Nakatsuka-San decided to use his own resistors made of pure copper wire, same material as a copper wire of MC carts. In order to playback the sound info of LOMC carts in 100% fidelity, CPP-1 headamp has special circuit in the simplest amplification circuit.

Great device to avoid SUT !

Dear chakster, ''Great device to avoid SUT'' is obviously meant

to ''belittle'' your Slavic brother. But if I am well informed you just

bought some cheap Italian phono-pre dismissing this way your

technical praise about ZYX CPP-1. The other possible reason is

 your  effort  to sell this ZYX to me. I am sorry but I am happy

with my Basis Exclusive as well with my Klyne 7PX 3.5 + Denon

AU-S1.
