Digital Coax 1.5m

Personally ,I don't hear any (unbalanced ) sound ,just a change in signature  .

What you hear should only be applicable to one channel, the one that does not have the input directly but through the link cable.

That's very strange what you're saying,as it means DEVIALET as a company designed  these didn't wanted left and right channel  sounds different,  we're they?

Anyway from myself I can only confirm the better linking cable ,the better sound quality (without any obvious imbalance) between left and right channel I can hear.

It's very simple, the Devialet monoblock setup uses the master unit as the "preamp" if you compare it to a traditional dual mono setup which has one physical preamp and two monoblock power amps. Since the master unit works as both a preamp for whole signal and a power amp for one channel, whatever is carried by the link cable only applies to the other channel. Someone here says that the sound quality changes depending on which link cable is the sound quality of the companion unit. (or vice versa in case an input of the companion is used)
