RCA to XLR ground lift

[Bertie]

Inspired by another forum post, I’m looking to ground lift my Neutrik RCA socket to XLR male adapter. It currently has the red wire soldered to pin 2 and the black wire soldered to pin 1 with a connection joining 1 to 3. I’m thinking the black wire should be soldered to pin 3 only and pin 1 should be redundant. Correct?

Hello, i´m curious   has the tuning brought an improvement for you? 

Not that I’m aware of. Maybe I’d be better served pursuing a hobby less reliant on the acute auditory prowess our other tweakers have. Either that or I’ll have to resign myself to replacing major components to get my hit.
