Confused about adapter for RCA to BNC

@stuartk - The analog rca jacks in the X SE are "Furutech rhodium plated low-mass RCAs directly soldered to the PC board." The digital S/PDIF rca jack looks different so I am not sure whether that is a Furutech or not. However, I have never had an adaptor or digital rca cable fit loosely so that is very odd about the Cardas adaptor.

Because I've run into a situation where the barrels on an rca IC pair didn't fit the Jacks on my Hegel H390 (several other cables fit just fine), I'm inclined to give the dac builder the benefit of the doubt but I can't definitively prove whether it's the dac or the adapter that's to blame in this case. 

I'll just have to see how the adapter that I'm expecting to arrive later in the week fits. Hopefully, it won't continue to be be an issue, going forward.

And the cardas adapter fits just fine on the rca outs of this dac? Interesting to try it just to check.
If the new adapter isn’t a tight fit I would reach out to the manufacturer and confirm i looked at a few pictures and I see different connectors are used for coax in and it’s not consistent from dac to dac…this is typical with boutique manufacturers as they would use whatever is available  I’m not excluding the possibility for that being the case even with the parts used inside the chassis as well.

To be honest, it never occurred to me to try it on the analog outputs, as that wasn’t what I would be using.

Note that when @mitch2 looked at his Mojo Mystique XSE, he said "The digital S/PDIF rca jack looks different". I can’t see a discernible difference on mine but it’s entirely possible he’s detecting a difference I’m overlooking. After all, it happens all the time that I can’t find something and my wife points out that it’s right in front of me! ;o)

@stuartk no big deal. I know you wouldn’t be using it on rca outs but thought to have an additional data point to determine the culprit…is it the Mojo rca jack or the cardas adapter that is the culprit. 
 

You don’t want to give up on your Mojo DAC and end up like Austin Powers….
