@thiefoflight With the Connex/DH Labs BL-Ag bulk wire I use KLEI solid silver RCAs and Neutrik XLRs. I have a hankering to try some boutique XLRs with this wire, but have not gotten around to it. My thought is that to obtain top performance from a fancy XLR plug, it would be a good idea to also upgrade the panel-mounted XLRs in the chassis-- which is a PITA.
BL-Ag wire also makes a good low-capacitance phono IC.
