Huh, I had the complete opposite result when using BNC-to-RCA adapters. On the exact same cable, I had much better high frequency resolution and results with using BNC connectors on the end of the cable and them BNC-to-RCA adapters. When using the same exact cable with only RCA plugs, I lost high frequency resolution and air in the sound. I used the best RCA plugs as well.
Another s/pdif digital cable thread
When I set up my system and cabling some years back I was blissfully unaware of difference between 75 ohm and 50 ohm BNC connectors. I just thought BNC was BNC. Most of my digital gear already has 75 ohm BNC female connectors for s/pdif inputs & outputs. Some, however, has RCA sockets.
On close inspection
I recently discovered that the cables all have 50 ohm RF connectors. And a couple are 50 ohm BNC at one end and RCA at the other.
IOW, it's a connector and impedance mashup salad and I want to sort it out right. First, the 50 ohm connectors will get scrapped and replaced by proper 75 ohm connectors. Then I'll use 75 ohm BNC => RCS adapters instead of the BNC/RCA frankencables.
So here's the question: how much degradation do all these mismatches create? Seems like there should be a ranking of these scenarios.1. Proper 75 ohm BNC + 75 ohm coax everywhere. The right way, next step.
2. [50 ohm BNC connectors + 75 ohm cable] to [75 ohm equipment connectors]. What I got now.
3. [75 ohm BNC + 75 ohm cable + RCA] to connect "mixed" equipmen. Also what I got now.
4. [75 ohm BNC connectors + 75 ohm cable] + BNC/RCA adapter to [mixed equipment connectors] . Next step.
Any comments or suggestions would be great. I'm hoping for a big improvement - but time will tell. Thanks,
