I own it and the Off-ramp 5 (coax + i2s upgrades + TeddyPSU).
The Ciunas is a much better value but has limited connectivity.
The OR5 makes everything sound a bit darker but has better separation and focus. It is not as convenient to use (bigger box, separate PSU), much more expensive... But it is the better converter, so...
The Hydra-X+ looks very interesting feature-wise (i2s + battery) and 6moons rated it's performance up there with the 2-box SOtM solution.
Can you describe more about the OR5 and Ciunus differences? Lets say you were to i2s the Ciunas and run a Teddy PSU with it. Do you think things get a little more evened out or not quite? Trying to figure out where the Ciunus would need to be modded to go neck to neck with the OR5 setup you have.
