![]() I'm not sure the Blusound node has an spidf rca inputt, it has a toslink imho, the opposit for the Asus stx dac headphone card for computer. ![]() ![]() The only good think I could see in the MAudio connectors adaptator is to use the rca to a short toslink ability to break noise from the ground if a big personal computer is at the party. I'm also more worried by what are between the active part signal source and the connector in the same board and the same on the receiver side on the board of the other gears. I may be wrong as I'm not a specialist but the op should not worry buf if it's simplier to use Bnc for him because interconnects and gears move often and stay away from the MAudio connectors adaptator BNC is good as said for HF, contacts are better and thiner for sure and I also believe it helps as aboos and Jean-Paul said. I don't believe trully in data loss with short spidf coax length and ths 0,5 V mostly used for spidf in coax signal transport and with HF below the Ghz AES/EBU being a different story for spidf in the professional uses. And there is a chance jitter not to be important as modern soundcard and dacs buffer this signal and often now reclock it before to send it in the modern dac chips. Ifnthe spidf cqble is less than 1 to 2 meter I will not bother. I mean there is a chance that the tweak towards bnc makes it worse by extra soldering, ads of micro coax between the bnc and the pcb if mandatory due to pcb holes and socket feet mismatching. I'm not sure what the most important here is the impedance break due to the rca socket (indeed few are 75 ohms while it exists) because it works as said by J-P enough with any non 75 ohms rca(while it doesn't hurt to stay 75 ohms if your bnc are true 75 ohms, as 50 or 110 ohms exist as said already). Less hassle indeed if it's the goal to make it plug n' play and simple and also less loss. to avoid active connectors adaptators as the M-Audio. I'm not sure the impedance mismatch of the connectors to be very important nowadays with modern dacs qnd in your conf, but more the type of connectors to make simple and more direct links and also shorter (less capacitive), i.e. Then this cable should be the less capacitive to reduce high frequencies filter effect due to dielectric loss. Imho the important facfor is the cable, indeed it should be 75 ohms if gears manufactors has followed the spidf standard. Same by the way is also true for RJ45 network stuff - this system was designed for RF signal transmission (which is the case for Ethernet LAN) via twisted pair cables with 110 to 120 Ohm impedance. (be aware that BNC normally is a 50 Ohm system while most TV stuff is 75 Ohm) The reason for sound differences between digital cables are simply differences resulting from RF signal distortions introduced by RF signal reflections due to impedance mismatches between board, cable and connectors imho.īNC has been designed with RF stuff in mind and using 50 Ohm coax cable with BNC connectors ensures good impedance matching. And the typical RCA cables used are undefined on top. But SPDIF is an RF signal (and not an audio signal) and clean and distortion free signals are a must for the receiver to extract and recover the clock signal with lowest possible jitter. RCA connectors were and are not designed nor characterized for their chracteristic RF impedance.
