Master/slave link

[aerki]

Hi,

My own tests led me to the conclusion that this link is of the utmost importance. There is here a large room for optimization.
So much more SQ hidden by this cable that I would have believe when starting my test campaign
Straight to the point, I am using now a special cable between RCA (Master) and AES EBU (slave). By special I mean including a transformator on the signal path.

The purpose is to avoid that any reflected wave (due to impedance mismatching on the connector side) comes back to the opposite electronic.

I found such a cable from a small french designer (audioprana, look here at this ugly website http://audioprana.free.fr/catalogue%20ve...0ligne.htm , description in french: Câble de symétrisation sortie source rca/spdif 75 Ohms vers entrée AES/EBU 110 Ohms (fiches bois précieux) 260€). Transfo is done with the same silver signal cable, no interruption, no soldering (otherwise impedance issues...).
There are also some additionnal refined stuff, e.g special wood connectors (vibrations, no metal = no antenna) etc

Again, this type of solution grants that no disturbance will come back to the electronic.
It releases a brand new potential for the D400/ D800, miles away from what you get out of the box (Here that was a crystal cable like some of you).

Hope you'll find something similar in UK

NB: the diy direct wiring solution (RCA to AES/EBU) currently suggested by the manufacturer on their website works but makes eventually no sense. With this you can only get basic sound, which coincidently means that you are throwing away the money of your companion (This is supposed to be bad habits, am I wrong ?)
