Cartridges in general

Dear Jcarr, You are as always kind, polite and helpful.
But your 'help' is a mixed blessing. First of all I started
this thread to help you with YOUR idea to extend the MM
thread to more kinds of carts than MM and MC kinds only.
At high shool my best friend was , in my opinion, an
mathematical genius. But he was not able to imagine my
problems with math. He kept repeating: 'it is so easy,
you know'. I still have no idea how I passed math at high
school but my guess is that this had something to do with
my dad who was a bank director.
So many years later I am confronted with, uh, similar problem.
I see that my understanding of electronics is simialr to
my understanding of math. I hope you will not state:
'it is so easy, you know'.
I think that for us the mortals the best method of explication
is the comparison of what is known to us and
then from there lead us to the unknown (for us). After so
many years of participation in the MM and the MC 'subject
matter' we may be assumed to understand something about
those two kinds not only thanks to our better 'equiped'
co-members but also thanks to our own extended experience
with the mentioned kinds.
But I am sure that all our members are curious to learn
from you about and eventual try those for us 'exotic kinds'.

Kind regards,
Nikola

My friend Dertonarm try to convince me to use a SUT 10 years ago. I was
scared by their complexity as well by my own perspective with my + 40 MC
carts because I thought that ech of them would need an special SUT.
The ''pudding methaphor'' crossed my mind recently so I started with the FRT-4
which can be used with the most MC carts . The price which was lower than any
of my MC carts was an added argument. I was so surprised with the result
of  proof ( aka ''the pudding'') that I asked myself what the result would be with
an more expensive SUT? This kind of questions ''explain'' my + 40 MC carts
btw. So I bought the Denon AU-S1. Build like a German tank but with the minimal wire connections possible. A kind of simplicity added to complexity.
There is no way back to exotic and expansive MC phono-pres. I should listen
to my friend Dertonarm 10 years ago.

Hi analogluvr, Yes much better but I need to confess that I am a novice in
this domain with limited experience . I own only two SUT's  which I mentioned
while I started with the FRT-4 only 4 months ago. There are many members with
more extended knowledge and experince than me. They should provide better
information about comparisson between those two. The more expensive FR SUT's are made for specific impedance while the FRT-4 is made for ''all purposes'' with 3 , 10, 30 and 100 Ohm as well 3 input possibilities and bypass.
This imply many wire (aka ''soldering points'') and cheap (aluminum) switches.
The transformers by the Denon are direct connected with the output and input
connectors reducing '''soldering points'' to a minimum.

Hi dear Thuchan,we missed your contributions for some time. I am glad to see
that I provoked you to react. Alas only a part of your statement is true. The one
about my carts(+ 50). I own since recently just two SUT's : FRT-4 and Denon AU-S1 . But I should listen to our genius friend Daniel 10 years ago. I forget
his argument but , if I am right, this has someting to do with 'mutal' relationship
between impedance and inductance of both components. This argument scared me to dead because in my interpreation this meant separat SUT for each of
my MC carts. You should be thankful because in this case I would need to lend
the money from you (grin).
