Master/slave link

[aerki]

I fully agree with you guillaume

This sync link is a serious issue for those having been investing a bunch of bucks, kiwis or whatever in the 2 amps.

I am currently busy evaluating vqrious cables.

Moreover i don't know so far what's the best option to go for: rca/rca or rca/aesebu.

The rca/aesebu is a tricky one, since on one side you have to comply with the 75 ohm impedance, versus 110ohm on the opposite side.
And when you know a bit of the basic physics for coax cable (impedance depending on diameter, thickness and type of the insulation material), this is simply not possible to obtain this just by soldering the wires on the right pins of a rca or xlr connector.
(As adviced on the devialet website )
To do it properly, it requires an impedance adaptation, with a large bandwidth

I will be testing this option next week. I ve ordered such a special cable from a french cable manufacturer, fyi see audioprana website. They call it symetriseur.

Canare is providing an impedance adapter for those who like diy...
