Doug Schroeder Method, Double ic

Will this method work between a DAC and the Line Magnetic 508IA integrated tube amplifier?

For those who have experienced improvements by doubling up, what was the gauge of the original single interconnect in your situation?

@douglas_schroeder Do you know if this method would work with ICs connecting a DAC to a tube integrated amp?

Also clarification on how to implement it, it's simply soldering two sets of interconnects to the same terminal on the connectors correct?

Thanks in advance.

@douglas_schroeder Thanks for the reply. Do you know if the popular R2R DACs from Denafrips (Terminator, Venus) are compatible with this method?
