master / slave digital cable for 440Pro

[daniel.avasilichioaei]

Changed mine from RCA (digital) on master to RCA (digital) on companion, to...

RCA (digital) on master to AES on companion, leaving out the earth connection, instead



There is an improvement in clarity and detail.  This did not become immediately obvious, but the reproduction, especially on good classical music recordings, is worthwhile

Especially since a vdHul RCA plug and a silver-plated XLR plug, plus a 150mm piece of 110 ohm cable cost under €3,00 and took 30 mins to make

Did the sound improvement appear only in the speaker connected to the companion (the one to which you changed the input) or did you also feel an improvement in the sound of the speaker connected to the master?
I ask you because the master only sends the signal and then it should not have been affected by the change in the input from the companion.
After you made this change, did you notice any difference in sound quality between the two speakers?
