Like you said 75-Ohm RCA conenctors don't exist but everyone including Meridian uses them. So why bother switching to BNC just here.
Indeed, I agree, why bother. The reason I even thought about it, because my intention is to use the modified Ocatava in a set-up that will exclude the Meridian, - hence my 568 is for sale now if anyone wants it.
So, I was thinking of using the BNCs on Octava because the unit the Octava is going to be plugged in to could also use BNC connectors. In the context whereby the Meridian gear is used, the use of BNC connectors makes little sense.
In any event, at this time I have the Octava box and I just received Shawn`s 4x SPDI/F board. I will take pictures of the process and when I am done, hopefully soon, I shall post them.
The Octava circuit board is all surface mount components and they are rather tiny. So my feeling is that unless you have experience with soldering and working with surface mount parts, this mod is not for you. Shawn provided me with pictures of the mod that he did, and I intend to use it as a guide, but there is one complication so far as I see it, - the Octava`s board has a re-work in the area where the wires must go. This complicates things, so we will see how it goes. In the end I will most likely drill new holes and install plain vanilla RCA plugs, just like Shawn did.
