I think the Rockna can perform preamp duties as well, but it would probably come down to how many sources you have as to whether or not that helps justify or offset any of its cost. I’m following Mike Powell on YouTube and his comparisons between Vermeer, Rockna, and Terminator are a lot of fun to watch, even if the format limits its ultimate effectiveness.
I wish they would settle on an i2s via HDMI standard, because as it stands I think there are some proprietary pinouts for sources and DACs so a custom cable may be necessary if the pinout on the CDT-2 isn’t exactly matching the DAC you end up with.
That said, and realize a LOT of variables have changed since this time, but I ran i2s from an audio PC to an Aqua DAC several years ago and just IMO, the Jay’s --> DH Labs Silver Sonic BNC --> Yggdrasil, which at least costwise is very equivalent to my old setup, is not just on another plane, it’s in another dimension for resolution and musicality. I say that just to make the point that i2s while theoretically better, it has its own limitations. Cable length used to be absolutely critical for it to work well. I used a 6" Cat6 cable back then, with the DAC stacked on top of the audio PC. Maybe it’s different now but just some food for thought.
