But you wrote this: > XLR connectors........they really are 110 ohms. But, like he > said..........they don't stay that way. (Hint: look at how far apart > the pins are, and how long they are. Look at a BNC. See why now?) So I did and failed to find any clue. When I write about my thoughts and ask you to explain it, you react like in the first quote. This tell me that you either can't explain it by distance and length of pins of xlr compared to bnc or you can't handle anyone who actually tries to understand what you mean and asks questions. Fine by me, but you should understand that posting bold statements in an audiophile forum leads to replies like mine and when you don't care to explain your statements, what's the use of making them? I did try to find measurement results on the web but failed (AES has some but it costs $20 to find out if the wanted info is actually in their docs). But when you did this yourself, you could tell me your findings! I did find interesting TDR tests about using 50 Ohm BNC connectors on 75 Ohm cables which leads me to think that for S/PDIF there should not be a problem. The link is: http://www.extron.com/company/article.aspx?id=demystifyingcables1 Figures 6-8 are these measurements. > As for making a 75 ohm RCA: > Give me a break. it is not possible.

Well, I tried and run into trouble where the center pin exits the shielded part (any match ends there) and possibly (but frequency of the signal is a variable here) the center pin is too thick. So, I agree. cheers, Nick. -- DeVerm ------------------------------------------------------------------------ DeVerm's Profile: http://forums.slimdevices.com/member.php?userid=18104 View this thread: http://forums.slimdevices.com/showthread.php?t=52817 _______________________________________________ audiophiles mailing list [email protected] http://lists.slimdevices.com/lists/listinfo/audiophiles
