Arrows on cables.

It’s always going to.. So from out to in.. make sense?

Output of the turntable and onto the phono preamp input. ------->

Output of the phono preamp and into preamp input. -------->

OR

Output from ANY source and into the preamp input. ------>

Out of the preamp output and into power amps input. ------->

Output of the power amp (s) and into the speaker terminals. ------>

Arrows point always from the outs and into the ins.

Clear as mud..

The arrow always points to the next piece of equipment in the chain. (Source to pre, pre to amp, source to to DAC to pre and so on).

Follow the electrons.

Flip a coin! Wire directionality is complete NONSENSE!

I guess I have it easy - my turntable connections are not removable, the rest of my interconnects are balanced cables and my speakers are internally biwired.
