Paul, thank you for your input!

I think with the SUT the "dynamic" loading the cartridge "sees" may swamp the choice of wire metal.  Once the loading is dialed in, silver might be nice. 


Yes Paul, absolutely agree--the electrical parameters must be dialed in first. What I'd see ideally is a SUT custom designed
for the cart--FR7f. The idea of silve comes loosely from the fact that the Bavarian seller  was comparing my cart with his
own special FR7 with silver coils and reported a slightly more, as he has put it "soul", to the Sound. This is of course a very
shitty "motivation", as this was a 2nd hand opinion of someone whose system I do not know and moreover
a cart's coil and a SUT (ass-u-ming all other factors equal) are very different coils, but...who knows...

Slagle can make a custom silver SUT but he uses mumetal. From the reports in the net (no 1st hand exp. on my side),
mumetal is said to be more "relaxed", amo more "clear, fast" to put it simplistically. I'm more on the "clear" side...at least in my
imagination. I also remember talking with a magnetic metallurgist, who claimed cobalt amo and nanocrystalines are the
most linear magnetics known and he laughed at mumetal...well, weather this guarantees anything is of course disputable,
but an intellectual picture has formed in  my mind: a clean, fast, "harder reading" core + supposedly "detaily relaxed" silver,
then luxuriously soft-but-fast EAR834RtC...I'd like to check it.

The Silvercore guy replied that his 1000Eu/piece more expensive SUT uses bigger core and more silver...I know the prices of
amo/nanocores, I still have an insanely huge Tribute prototypes, I also know how much Pieter pays for his large cores
and I can't justify +1000Eu/trannie at the moment. Let's hope I'm able to convince Pieter to wind in silver....

Another option is a silver Lundahl LL1941Ag. 

Cheers,
N-set
