@taylorro Interesting.
Currently, I own both the X260.8 and the JC1+ and have A/B’ed them several times.
Conclusion: Pass is more musical / euphonic.
I currently have two sets of speakers at home: Focal Scala Utopia (sold to someone, awaiting delivery) and Focal Maestro Utopia III.
The Pass sounds better with the Focal Scala Utopia (and I expect it would sounde better with a majority of speakers). However, the Maestro III are notoriously hard to drive - and with these, I prefer the JC1+.
So, my X260.8 shall be put up for sale soon.
