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?

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.

No, ZYX CPP-1 is a keeper, i like it a lot with some of the MC cartridges, particulary with my Klipsch MCZ. I thought someone can comment about ZYX unique input resistors made of a cartridge coil wire. It's a know how. I think it's a compliment to a LOMC cartridge to amplify signal like that. It's like external cartridge coil with more wire not inside the cartridge, but outside the cartridge in a separate box.

@bimasta, Your prose reads like a poem.  I was really

moved by your loyalty to FR-201.  I have similar feeling for

FR-7fz.

@nandric — A poem? From a mutli-leveled literary stylist like you, that’s high praise!
@analogluvr — One brief vignette how cool that meet was. I approached a table laden with goodies. I saw a clear plastic bag stuffed with, bursting with, cartridge-mounting nuts, bolts, washers, gold cartridge clips, 1000s of them, for $3. My hand was an inch away from it when my eye caught something less than a foot away — still-sealed new Shure V15 IV-MR for $40. "You're Next!" I thought as I turned back to the $3 bag – but someone was buying it. Too late! I reached for the Shure and someone was buying it too. Damn! "But I saw it first!" didn’t work there, I didn’t bother trying. Two great things lost in half a second. Never again! I moved to the next table ready to pounce...

Chakster, To create a "resistor" using copper wire is folly, don't you think?  Even fine copper wire has very low resistance per foot, because it is.... a great conductor.  You'd need miles of good copper wire to create a 47K ohm resistance, for example.  I suspect there is some other kind of wire used in there, like nichrome, which is popular for resistors because it is a bad conductor.  As to the lack of inductance, there are very fine non-inductive wirewound resistors, made by Mills and probably others. But even those are not totally without inductance; the wire is wound so as to minimize inductance, but I think there will always be a tiny amount of inductance in any wirewound resistor.
I looked it up for fun:  1000 feet of 30 gauge solid core copper wire has a resistance of about 100 ohms.  So you'd need ~470,000 feet of it to create a 47K ohm resistor.  I don't think that would fit into the ZYX chassis.
