Sonore opticalRendu

Hello everyone, I am having the opportunity to change my Ultrarendu into an Opticalrendu.  
 

I know that these comparisons have already been made, but I didn't see a unanimity favoring opticalrendu.  

 

My network is already via optical cable separating the dirty side (room where the Core Roon + HQPLAYER is) in the sound room this fiber reaches a Sotm Switch and from there it goes to the Ultrarendu via network cable (CAT-7 Sotm with filter) after - Matrix - Directstream DAC.

 

 I would like to know if in a scenario like mine this upgrade would be consistent or not, if you opt for Optical I would dispense with the Sotm switch.

 

 Optical prices are pretty steep here in Brazil, costing more than twice as much as Ultra, this upgrade would have to be consistent and unambiguous to be worth it.

I return to report my experiences.

I tested OpticalRendu on my set and I liked the results so much, I ended up buying it.

I already used the UltraRendu with optical fiber isolation (on the dirty side, a Ubiquiti with fiber output that in the sound room reached a Sotm switch) and even in this scenario the OR is better in every way, the most obscure details of the music become even clearer, the detailing is incredible and the bass gains body and presence.

 

The fiber that I use from the living room to the sound room runs 20 meters inside the wall and is multimode, I did a test with double conversion (Ubiquiti - switch Sotm - OM - OR) and in the last segment the fiber it is of the monomode type but the result was not pleasing, it was worse than just optical direct to multimode fiber.

 

The “o cing on the cake” was adding a Sotm CAT7 cable with a Core filter to the Ubiquiti, this ended any trace of digital artifacts in the sound and the musicality was incredible.

Next step will be to put a linear source in the Core, if it responded so well to the cable I believe that with the source it can respond even more.

 

This was a doubt I always had and I didn't find unanimity, if the "dirty" side of the network could influence the sound, my experiences unequivocally indicated that yes!!!
