Hi,
I did tests with RCA to AES/EBU with semi coupled (on the XLR side) 75 ohm cable and also with a 75/110 ohm transformer and to me there was no difference (between master and companion), however just using the AES/EBU input had welcome gains. I think the Audioprana cable used by Confused has a built in 75/110 ohm 'converter'.
In a way my own results from testing indicated that Thierry was right when he told me that the digital RCA output is not to std SPDIF 75 ohms anyway so using a 75 or 110 ohm cable does not matter as well as transformer, even if he recommended 110 ohm cable. He just concluded that AES/EBU is superior with its transformer driven input.
Still has to test with a 110 ohm cable which I will at some point.
The situation is though different when it comes to my streamer (Unitiserve) there I have a real 75 ohm output (BNC) and there I noticed a real effect from 75/110 ohm transformation ie same as without transformer but more analogue sound, less stressed performance, details, but specially better timing of the music.
