As you know, in my case I’m going Oppo>Yggy via **RCA** coax out from Oppo and in to Yggy. Shame on me perhaps, but other than optical this is my only option. Or is it? :)
The other option is to use a BNC-BNC cable with 75 ohm RCA adapters. This is better than a cable terminated with RCA's. Like anything there are cables and then there are great cables. You get what you pay for.
Technically I could go RCA coax out from Oppo and terminate with BNC coax in to Yggy. So is RCA>BNC coax "better" than RCA>RCA coax? (same coax and all else equal)
Yes, anywhere you can use BNC you should do it.
