I have a phase inverting Cary 98P. I correct this at the speaker terminals.
I also have a Feliks Euphoria head phone amp the is fed from the amplifiers second set of amplifier outputs to the Feliks amps inputs, how can I phase invert this?
Could I swap the + & - soldered connections on one end of the each L &R RCA cable or swap and resolver the output wires inside the amp leading to the rca connections? (This looks like it is easy) ?
