@jaybe PartsConnexion is certainly going strong. They are offering a price reduction on the Duelund wire currently...at least they were yesterday when I bought some. They also have a quite favorable price on the KLEI banana connectors, if you were thinking about using those.
@grannyring I agree with you about how good the Furutech spades sound and
on almost all my terminations
I have used either the FP-203 (crimp or solder connection) that I have available for this project or the FP-201 (bigger and with set screws). Both of these spades are pure Alpha copper with gold (my choice) or rhodium plating. I have previously used my hydraulic crimp tool with the FP-203 spades but this time I think I will lightly crimp with a hand tool and then solder. The solder should mix with the tin plating and create a more homogeneous connection.
