At about the same time I discovered that the importer of the KR Audio amp I had for review refurbishes SME arms as well as Thorens and Oracle tables.

So I sent him the arm.

Now it's back with 6 feet of Cardas wire that runs in one piece up through the arm to the headshell and terminated with Cardas RCA's.
I don't know about the "golden section" part of the wire alchemy but it's double shielded like Belden 1505 and I'm hearing a better defined soundstage with quieter backgrounds.

Pretty reasonable cost, $175, for me who can't see to thread the fishing line through the bias weight!
